Concrete Calculators
Concrete calculators for every element (slabs with thickened edges, rectangular, stepped and sloped footings, columns, walls, beams, rafts, blinding and bored piles) plus ready-mix trucks, bags, cement, sand and aggregate for site mixing, and a wastage calculator that shows where the extra concrete goes. Every result shows the working so you can check it before you order.
Beam Concrete CalculatorCalculate concrete for beams (below the slab or full depth) for any number of identical beams, with ready-mix order or cement, sand and aggregate. Free accountBlinding Concrete CalculatorCalculate blinding (lean) concrete under footings (with a margin beyond each footing) or under a known area, plus cement, sand and aggregate for 1:3:6 or 1:4:8. Free accountCement Bags EstimatorCalculate cement bags, sand and aggregate for concrete by mix ratio (1:2:4, 1:1.5:3, M20, M15) using the dry volume method. 50 kg and 94 lb bags.Column Concrete CalculatorCalculate concrete for rectangular or circular columns, with cement bags, sand and aggregate for site mixing (M20, M25) or ready-mix order quantity. Free accountConcrete Bag CalculatorHow many bags of concrete do you need? Calculate 40 lb, 60 lb and 80 lb bags (or 20–30 kg bags) for a slab, with wastage and total weight.Concrete Cover CalculatorMinimum concrete cover to reinforcement for slabs, beams, columns, walls and footings, by exposure, to IS 456:2000 and ACI 318-19, in mm and inches.Concrete Truck CalculatorWork out how many ready-mix concrete trucks to order for a slab or pour, with wastage, the order quantity and the size of the last load. Metric and imperial.Concrete Tube CalculatorCalculate concrete for Sonotube and round form tubes: volume per tube, cubic yards, and 60 lb or 80 lb bags. Includes a bags-per-tube table by diameter.Concrete Volume CalculatorCalculate concrete volume in m³ or cubic yards for slabs, footings, beams, walls and round columns, with wastage and approximate weight. Working shown.Concrete Wastage CalculatorCalculate concrete wastage by cause (uneven subgrade, spillage and pump priming) as a percentage and as volume, with the order quantity and ready-mix trucks.Footing Concrete CalculatorCalculate concrete for rectangular, stepped, sloped (trapezoidal) and strip footings, with ready-mix order or cement, sand and aggregate for site mixing. Free accountFooting Quantities CalculatorCalculate concrete, blinding, formwork area and excavation for isolated pad footings. Enter footing size, depth and number of footings; working shown.Pile Concrete CalculatorCalculate concrete for bored piles (theoretical volume to cut-off plus overpour, and expected volume with over-consumption) per pile and in total, with trucks. Free accountRaft Concrete CalculatorCalculate concrete for a raft (mat) foundation with downstand beams and column thickenings, ready-mix trucks and continuous pour duration at your pump output. Free accountSlab Concrete CalculatorCalculate concrete for a slab with thickened edges and openings deducted, concrete per m², order quantity and ready-mix trucks. Metric and imperial.Wall Concrete CalculatorCalculate concrete for a wall with openings deducted, volume per lift, time to place each lift at your rate of rise, supply rate needed and ready-mix trucks.
