Calculate concrete volume, materials, and costs for construction projects. Perfect for contractors, builders, and DIY enthusiasts.
Concrete volume is calculated by multiplying length × width × height (or depth). For irregular shapes, break them down into regular geometric sections and calculate each separately.
Standard concrete mix ratios are 1:2:4 (cement:sand:aggregate) for general construction, 1:1.5:3 for reinforced concrete, and 1:1:2 for high-strength applications. Water-cement ratio is typically 0.4-0.6.
Foundation concrete requirements depend on the foundation type, soil conditions, and building load. A typical residential foundation might need 0.3-0.5 cubic meters per square meter of floor area.
Concrete strength is affected by water-cement ratio, curing conditions, aggregate quality, cement type, and mixing procedures. Lower water-cement ratios generally result in higher strength.
