Questions people ask
How much cement, sand and aggregate for concrete?
Work out the wet volume (length × width × depth), multiply by a dry-volume factor (1.54 by default, change it) and share it by your mix, e.g. 1:2:4. The page shows bags of cement, sand and aggregate in cu m and cft.
Can it do a slab in feet and inches?
Yes — choose feet for length and width and inches for the thickness.
Which mix should I use?
That depends on the work and the design — ask your engineer. The page works with any mix you type.
Is my data uploaded?
No. Everything is worked out in your browser and the PDF is made on your device.
