How to Calculate Quantity of Cement, Sand & Aggregates

How to Calculate Quantity of Cement, Sand & Aggregates for Slab. October 18, 2018 by Kathir Leave a Comment. Area of flat slab = 1000sq.ft = 93sq.m. The minimum thickness provided for slab is 150mm. (As per IS 456) 150mm = 0.15 metres. Hence Wet volume = Area of slab x Thickness of slab. Wet volume = 93 x 0.15 = 13.95cu.m. To calculate the quantities of materials we need dry volume.
