Enter your project requirements for accurate delivery planning
A concrete truck load calculator determines how many ready-mix concrete trucks are required to deliver sufficient concrete for a construction project. Ready-mix concrete is delivered in specialized mixer trucks that maintain concrete workability during transport through continuous drum rotation. The Concrete Truck Load Calculator helps contractors, builders, and project managers estimate delivery requirements, coordinate schedules, and calculate costs for efficient concrete placement operations in 2026.
Truck capacities in cubic metres - actual payload varies by jurisdiction and road regulations
Proper load calculation prevents both concrete shortage (requiring emergency orders with premium pricing) and excess concrete (wastage costs plus disposal fees). Modern ready-mix suppliers offer various truck sizes to match project requirements. The calculator accounts for placement efficiency, wastage allowances, and delivery logistics to provide realistic truck quantity estimates supporting successful concrete operations.
Concrete remains workable 90-120 minutes from batching. Coordinate truck arrivals to maintain continuous placement without gaps (cold joints) or excessive wait times (premature stiffening). Proper scheduling prevents waste and quality issues.
In 2026, concrete costs $150-250 per cubic metre depending on strength, location, and additives. Delivery fees add $50-150 per truck. Ordering the right amount minimizes material waste (typically $500-1000 for excess concrete on small projects).
Calculate exact concrete volume using length × width × depth for slabs, or use specialty calculators for complex shapes. Add 3-10% wastage depending on project complexity, formwork quality, and placement method used.
Visual comparison of typical mixer truck capacities
Standard ready-mix trucks carry 6-7 cubic metres (6-7 m³) and represent the most common delivery size for residential and light commercial work. These trucks balance capacity with manoeuvrability, fitting through standard suburban streets and residential driveways. For a typical residential driveway slab (30-50 m²), expect 4-8 standard truck loads. The Concrete Truck Load Calculator helps determine optimal truck size based on project requirements and site constraints.
Mini-mixers (2-3 m³) and small trucks (4-5 m³) serve projects with restricted access, small concrete volumes, or specialized applications. These compact vehicles navigate narrow lanes, steep driveways, and backyard access where larger trucks cannot reach. Trade-offs include higher per-cubic-metre costs (10-25% premium) and more frequent deliveries requiring extended coordination. Ideal for small shed slabs, pathway construction, post holes, and renovation work where access matters more than cost efficiency.
Large mixers delivering 8-10 cubic metres suit high-volume commercial projects, infrastructure work, and situations where minimizing truck numbers reduces traffic disruption or site congestion. These trucks offer best value per cubic metre (5-15% discount) but require wide street access, substantial turning radius, and appropriate ground bearing capacity. Not suitable for residential settings with overhead powerlines, narrow entries, or weight-sensitive access routes. For large concrete pours, consider an aggregate quantity calculator for complete mix planning.
Round up to nearest whole number - you cannot order partial truck loads. Always verify with supplier regarding exact truck capacities and minimum order requirements.
Start by calculating concrete volume: For slabs, multiply length × width × depth (all in metres) to get volume in cubic metres. For example, a 10m × 5m slab at 100mm (0.1m) thick = 10 × 5 × 0.1 = 5 m³. For complex shapes, break into simple geometric sections, calculate each, and sum the results. Wall volume = length × height × thickness. Column volume = πr²h for circular, or length × width × height for rectangular. Footings often require trapezoidal calculations.
Always add wastage allowance to base volume calculations. Standard slabs with good formwork: 3-5% wastage. Complex formwork or irregular shapes: 5-8% wastage. Difficult access or pumping: 8-10% wastage. Multiple pours or intricate details: 10-15% wastage. Wastage accounts for spillage, concrete left in mixer drum, formwork imperfections, uneven subgrade, and placing inefficiencies. Under-ordering causes expensive short-load charges ($200-500) and project delays. Over-ordering by 10-20% provides safety margin without excessive waste.
Divide total adjusted volume by truck capacity, rounding up to nearest whole number. Example: 32 m³ project + 5% wastage = 33.6 m³ adjusted. Using 7 m³ trucks: 33.6 ÷ 7 = 4.8, round up to 5 trucks needed. The partial sixth truck prevents shortfall. Most suppliers charge full truck rate even for partial loads. Consider alternative truck sizes to minimize partial loads: switching to 6 m³ trucks yields 33.6 ÷ 6 = 5.6, requiring 6 trucks, but may offer better value depending on pricing structure.
| Project Volume | Mini Trucks (3m³) | Small Trucks (5m³) | Standard Trucks (7m³) | Large Trucks (10m³) |
|---|---|---|---|---|
| 5 m³ | 2 trucks | 1 truck | 1 truck | 1 truck |
| 10 m³ | 4 trucks | 2 trucks | 2 trucks | 1 truck |
| 20 m³ | 7 trucks | 4 trucks | 3 trucks | 2 trucks |
| 35 m³ | 12 trucks | 7 trucks | 5 trucks | 4 trucks |
| 50 m³ | 17 trucks | 10 trucks | 8 trucks | 5 trucks |
| 100 m³ | 34 trucks | 20 trucks | 15 trucks | 10 trucks |
Coordinate truck arrivals to maintain continuous concrete placement without excessive gaps or waiting. Optimal load spacing: 15-20 minutes for direct chute discharge with experienced crew, 20-30 minutes for wheelbarrow or manual distribution, 10-15 minutes with concrete pump (faster discharge), 25-35 minutes for difficult access or complex placement. Calculate total pour duration: (Number of trucks × discharge time) + (setup time). Example: 5 trucks at 20 minutes each = 100 minutes (1.7 hours) plus 30 minutes setup = 2.2 hours total.
Adequate crew size ensures efficient concrete handling before initial set. Small crew (2-3 workers): Suitable for 1-2 m³ per hour, simple slabs, direct discharge. Medium crew (4-6 workers): Handles 3-5 m³ per hour, standard residential projects. Large crew (7-10 workers): Required for 6-10 m³ per hour, commercial work, complex formwork. Insufficient crew causes truck waiting charges ($50-100 per hour), concrete stiffening in trucks requiring water addition (compromising strength), and rushed placement producing poor quality. For projects requiring precise calculations, use tools like a balcony slab calculator for specific area requirements.
Temperature affects concrete workability and placement timing. Hot weather (above 30°C): Reduced workability time, schedule early morning pours (6-9 AM), increase crew size, consider retarder admixtures, plan for 90-minute maximum workability. Cold weather (below 5°C): Extended setting times, insulation/heating may be needed, schedule midday pours (10 AM-2 PM) for warmer conditions, protect fresh concrete from freezing. Wet weather risks washing out fresh concrete; always have tarpaulins ready and avoid pouring during heavy rain forecasts.
In 2026, ready-mix concrete prices vary by strength, region, and specifications: Standard 25 MPa: $150-180 per m³. Medium strength 32 MPa: $170-200 per m³. High strength 40 MPa: $190-230 per m³. Specialized mixes (coloured, exposed aggregate): $220-300 per m³. Prices include batching, mixing, and quality control but not delivery charges. Remote locations or difficult access may incur additional fees. Volume discounts apply: orders above 50 m³ often receive 5-10% discount. Minimum order charges (typically $150-250) apply to very small orders under 2 m³.
Under-ordering requires emergency short-load delivery at 20-40% premium pricing plus $200-500 short-load fee. Over-ordering excess concrete incurs disposal costs ($50-150 per m³) plus environmental fees. Use the Concrete Truck Load Calculator to optimize ordering and minimize expensive mistakes.
Delivery charges depend on distance from batch plant to site. Within 10 km: $50-80 per truck. 10-20 km: $80-120 per truck. 20-35 km: $120-180 per truck. Above 35 km: $180-250+ per truck. Many suppliers include free delivery within 5-10 km radius with minimum order (typically 3-5 m³). Saturday deliveries often carry surcharges ($50-100 per truck). Sunday and public holiday deliveries (where available) incur premium charges ($150-300 per truck). Difficult site access may add $50-100 per truck for increased risk and time.
Concrete trucks require adequate access for safe delivery. Standard truck dimensions: 8-10m length, 2.5m width, 3.5-4m height (check for overhead powerlines, trees, or structures). Turning radius: minimum 12-15m diameter for large trucks, 8-10m for standard, 6-8m for small mixers. Ground bearing capacity: fully loaded trucks weigh 20-30 tonnes, requiring stable ground, temporary trackway over soft soil, or concrete placement via pump if direct access impossible. Verify no overhead obstructions along access route.
Plan concrete discharge location and method before ordering. Direct chute discharge: Truck can reach 3-4 meters from rear, requires firm ground positioning, fastest and cheapest method. Wheelbarrow distribution: Labor-intensive, suitable for small volumes or restricted areas, slows discharge significantly. Concrete pump: Extends reach 30-100+ meters depending on pump type, essential for multi-story, rear yard access, or long-distance placement. Crane bucket: Used for elevated pours, suspended slabs, or locations inaccessible to trucks and pumps. For specialized applications like equipment pads, reference an air conditioner pad calculator for dimension specifications.
Organize site before first truck arrives. Complete all formwork, reinforcement, and inspection requirements. Position adequate workforce at strategic locations. Prepare discharge points with clear access paths. Have screeds, floats, and finishing tools ready. Ensure vibrator equipment (if needed) is operational. Clear site of obstacles and tripping hazards. Protect adjacent areas from concrete splatter. Brief crew on placement sequence and finishing requirements. Verify concrete strength, slump, and admixtures ordered match specifications. Have site supervisor or experienced person authorized to sign delivery tickets confirming quality acceptance.
The most common error in concrete ordering is underestimating required volume. Causes include: calculation errors (forgetting unit conversions, using wrong dimensions), insufficient wastage allowance, uneven or poorly compacted subgrade adding hidden volume, formwork deflection or imperfections, last-minute design changes. Consequences of under-ordering: expensive short-load charges, project delays, cold joints reducing structural integrity, rushed placement producing poor quality, potential rework costs. Always add minimum 5% wastage allowance and verify calculations with the Concrete Truck Load Calculator before finalizing orders.
Order concrete 24-48 hours in advance with confirmed delivery time. Verify truck capacity and load spacing with supplier. Prepare site completely before first truck arrives. Have backup plan for excess concrete (paths, garden borders). Ensure adequate crew size for continuous placement. Communicate any access restrictions or site challenges when ordering. Keep supplier phone number handy for day-of coordination.
Inefficient scheduling causes multiple problems: Trucks arriving before site ready result in waiting charges and stiffened concrete. Excessive gaps between trucks create cold joints and finishing difficulties. Inadequate crew causes placement delays and rushed finishing. Starting too late in hot weather reduces working time. Never order concrete without confirmed site readiness, adequate crew availability, and appropriate tools/equipment prepared. Coordinate with ready-mix supplier regarding any special requirements, access challenges, or timing considerations. For complex projects requiring multiple concrete elements, consider tools like a basement access ramp calculator to plan different pours separately.
Site access problems discovered on delivery day cause expensive complications. Verify truck access route well in advance, checking for: overhead clearances (powerlines, tree branches), adequate turning radius at entry and on-site, ground stability supporting 20-30 tonne vehicle weight, neighbor parking or obstruction issues. Equipment failures include: inoperable concrete pump on pump day, vibrator malfunction during placement, insufficient wheelbarrows or labor for manual distribution. Always test critical equipment day before pour and have contingency plans for mechanical failures. Inform suppliers immediately of any access challenges so appropriate truck size can be dispatched.

CCAA Resources →Standard ready-mix concrete trucks in Australia typically carry 6-7 cubic metres (m³) of concrete. This is the most common size for residential and light commercial work. Mini-mixers hold 2-3 m³ for small jobs or restricted access. Small trucks carry 4-5 m³ for moderate projects. Large commercial trucks deliver 8-10 m³ for high-volume work. Actual capacity depends on specific truck model, local regulations, and road weight limits. Always confirm exact capacity with your ready-mix supplier when ordering, as capacities vary between suppliers and regions.
Calculate trucks needed by dividing your total concrete volume (including wastage) by truck capacity. Example: For a 25 m³ project with 5% wastage = 26.25 m³ total. Using 7 m³ trucks: 26.25 ÷ 7 = 3.75, round up to 4 trucks needed. Always round up because you cannot order partial loads. Add 3-10% wastage allowance depending on project complexity. Use the Concrete Truck Load Calculator to determine exact requirements based on your specific project volume, truck size preference, and wastage factors.
In 2026, concrete material costs $150-230 per m³ depending on strength grade and specifications. Delivery fees add $50-150 per truck depending on distance from batch plant: within 10 km typically $50-80, 10-20 km costs $80-120, 20-35 km ranges $120-180. Many suppliers include free delivery within 5-10 km for minimum orders. Saturday deliveries incur $50-100 surcharge per truck. Waiting time beyond 15-20 minutes costs $50-100 per hour. Short-load fees (emergency additional trucks) add $200-500 premium. Always get detailed quote including all charges before ordering.
Discharge time depends on placement method and concrete volume: Direct chute discharge typically takes 10-15 minutes for standard truck with experienced crew ready. Wheelbarrow distribution requires 20-30 minutes depending on distance and crew size. Concrete pump discharge completes in 8-12 minutes due to faster flow rate. Difficult access or complex formwork extends discharge to 25-35 minutes per truck. Always have adequate crew ready when truck arrives to minimize waiting charges. Suppliers typically allow 15-20 minutes free time, then charge $50-100 per hour for delays. Efficient site preparation and crew coordination prevent expensive waiting time charges.
Under-ordering requires expensive short-load delivery: additional trucks cost 20-40% premium plus $200-500 short-load fee, project delays while waiting for emergency delivery, potential cold joints affecting structural integrity. Over-ordering creates waste disposal problems: excess concrete costs $50-150 per m³ to dispose, environmental fees apply, supplier may charge for return concrete. Some contractors use excess for paths, garden borders, or equipment pads. Best practice: Add 5-10% wastage allowance to base calculations, use the Concrete Truck Load Calculator for accuracy, confirm calculations with supplier before ordering, have contingency plan for minor excess.
Yes, but you typically pay for the full truck capacity. Most ready-mix suppliers have minimum charges equivalent to 2-3 m³ even for smaller orders. If you order 2 m³ in a 7 m³ truck, you'll likely pay for at least 2-3 m³ plus full delivery fee. For very small quantities (under 1 m³), consider: bagged concrete mixed on-site (labor-intensive but economical for tiny jobs), mini-mixer trucks with lower minimum charges, or combining orders with neighbors for shared delivery. Some suppliers offer "short load" services with adjusted pricing, but expect premium rates. Always confirm minimum order requirements and pricing structure when requesting quotes.
Standard orders require 24-48 hours advance notice. During busy construction seasons (spring and early summer), book 3-7 days ahead to secure preferred delivery time. Large orders (above 50 m³) or specialized mixes need 2-5 days notice. Emergency same-day delivery may be available but expects 50-100% premium pricing plus limited time slot availability. When ordering, specify: desired delivery date and time, concrete strength and specifications, total volume needed, truck capacity preference, site access limitations, placement method, and any special requirements. Confirm order 24 hours before delivery and provide contact number for day-of coordination.
If trucks cannot access pour location directly, you have several options: Concrete pump hire ($500-1200 per day) extends reach 30-100 meters, essential for rear yards, upper floors, or restricted access. Wheelbarrow distribution (labor-intensive) works for nearby locations with pathway access. Crane bucket for elevated pours or locations inaccessible to trucks/pumps. Request smaller mixer trucks with better maneuverability (mini-mixers navigate tighter spaces). Always verify access route before ordering: check overhead clearances (powerlines, trees), adequate turning radius, ground stability, and neighbor parking issues. Inform supplier of any access challenges so appropriate equipment can be arranged.
