TEN CALCULATORS FOR YOUR PROJECT • Concrete slab: concrete for floor slabs from length, width and thickness. • Footing: rectangular strip and pad footings, one or many. • Column / round footing: volume for circular foundations and columns. • Concrete stairs: concrete for solid steps on the ground from number of steps, step height and depth. • Concrete bags: number of bags from volume and yield per bag, rounded up. • Concrete mix: cement, sand, gravel and water for site-mixed concrete at 1:1.5:3, 1:2:4 or 1:3:6 – including cement bags. • Floor screed: dry mix and bags from area, thickness and the consumption printed on the bag. • Gravel / crushed stone: volume and weight in tonnes for sand, gravel, crushed stone or chippings. • Bricks / blocks: block quantity from wall and block size, optional joint width. • Material costs: costs for ready-mix or bagged concrete with your own prices. WEIGHT, MIXER TRUCKS AND RESERVE Concrete results show the weight and the mixer truck loads you need. Choose 0, 5, 10 or 15 percent reserve; results show the base quantity and totals including reserve. Send a concrete result straight to the bags, mix or cost calculator.
