Aggregate Calculator
Uses a dry volume factor of 1.54 and an average coarse aggregate density of ~1500 kg/m³ (~100 lb/cu ft), consistent with the mix ratios used across the Concrete Material Calculator.
Block Quantity Calculator
Calculate concrete masonry unit (CMU) cinder blocks, mortar bags, and core grout fill volume for foundation and retaining walls.
Brick Quantity Calculator
Estimate brick units and mortar bags for single and double wythe walls with window/door opening deductions and waste allowances.
Concrete Material Calculator
Calculate exact dry raw materials (cement bags, sand tons, gravel stone, and water) for M15, M20, and M25 concrete design mixes.
Concrete Volume Calculator
Calculate concrete volume in cubic yards, cubic feet, and cubic meters for rectangular slabs and circular sonotube columns.
Concrete Weight Calculator
Uses the standard concrete density reference of ~150 lb/cu ft (2400 kg/m³), equal to approximately 4050 lb per cubic yard.
Mortar Calculator
Coverage factor default of 0.15 cu ft of mortar per sq ft of coursed masonry is a standard field estimating rule; each 80-lb bag of mortar mix yields approximately 0.45 cu ft.
Screed Calculator
Screed cement content is derived using the standard 1440 kg/m³ cement density and a 1.33 dry volume shrinkage factor for sand-cement screed mixes.
