AS 3600 concrete calculators and guides built for Australian standards
ConcreteMetric.com is Australia's premier resource for concrete professionals — featuring N20/N25/N32 calculators, AS 3600 design tools, mix design guides for GP cement, and construction resources compliant with NCC 2022 and Australian standards for 2026.
Built by Australian engineers for AS 3600, NCC 2022, and Australian concrete standards
Complete suite of AS 3600:2018 (Amendment 2021) concrete calculators for Australian engineers — rebar development length, shear capacity, flexural design, column interaction diagrams, slab deflection checks, and foundation design tools fully compliant with current Australian standards.
Australian concrete grades N20, N25, N32, N40, N50 with GP cement (AS 3972), 20mm aggregate, and realistic Australian mix designs. Slump, workability, pumpability, and exposure classification (A1, A2, B1, B2, C1, C2, U) calculators for all Australian conditions.
All tools and guides updated for NCC 2022 Volume 1 (BCA Class 2-9 buildings) and state variations. Fire resistance (AS 3600 Table 5.5), durability (exposure classifications), and structural performance requirements built into every calculator.
ConcreteMetric.com was created by CPEng chartered Australian civil/structural engineers who understand the unique challenges of concrete construction Down Under — from Darwin's cyclones to Melbourne's clay soils, Perth's corrosive coastal exposure, and Sydney's high-rise requirements.
Our calculators handle Australian specifics like 20MPa-50MPa characteristic strengths (N20-N50), GP cement (AS 3972), 10mm/12mm/16mm/20mm/24mm/32mm/36mm/40mm SL72/SL82/SL92 N12-N36 rebar, 20mm/10mm aggregate, and realistic Australian slump/workability requirements for pump, vibrate, and self-compacting concrete.
🇦🇺 AS 3600:2018 Tables: Direct from Clause 9, 10, 13, 14 design provisions. 🎯 State Variations: QLD, NSW, VIC, SA, WA, TAS, NT, ACT differences. 🌡️ Exposure Classifications: A1/A2 (inland), B1/B2 (coastal), C1/C2 (severe marine), U (cyclic wet/dry).
Registered Professional Engineers of Queensland (RPEQ) and Chartered Professional Engineers (CPEng) with Australian design experience in residential slabs, commercial footings, retaining walls, suspended floors, and multi-storey concrete frames per AS 3600 and NCC 2022.
Experienced Australian concreting contractors who understand realistic mix designs, pump line pressures, vibrator patterns, surface finishes, curing compounds, and wastage factors for Australian conditions and materials.
Australian concrete lab technicians experienced with AS 1379 testing, AS 1012 slump/flow tests, compressive strength cylinders (150x300mm), and quality control for GP, G, SR, SL cements per AS 3972.
Specialists in Australian residential (Class 1), commercial (Class 2-9), and industrial concrete design using Space Gass, Strand7, or ETABS with AS 3600 load combinations and capacity reduction factors (φ).
Australian concrete construction demands precision. Our tools eliminate guesswork with AS 3600-compliant calculations that work on site, in the office, or quoting from your ute.
🇦🇺 20mm Aggregate Standard: All mix designs use Australian 20mm/10mm graded aggregate. 🏠 Class 1-9 Coverage: Residential slabs to high-rise per NCC 2022. 🔥 Fire Tables: AS 3600 Table 5.5 cover & dimension requirements. 🌊 Coastal Exposure: B1/B2/C1/C2 classifications built-in.
