Как да изчислим Concrete
Какво е Concrete?
A concrete calculator determines the volume of concrete needed for slabs, footings, and columns, then converts that to bags of ready-mix or bulk quantities. Concrete is sold by the cubic metre (m³) in bulk or in bags (typically 25kg bags yield ~0.012m³ mixed).

- 1Volume (m³) = Length × Width × Depth (all in metres)
- 2Add 5–10% wastage for uneven surfaces and spillage
- 3Number of 25kg bags = Volume (m³) ÷ 0.012
- 4Typical mix ratio: 1 part cement : 2 parts sand : 3 parts aggregate
