Classification of Aggregates Based on Size and Shape ...

Aggregates are classified based on so many considerations, but here we are going to discuss about their shape and size classifications in detail. Classification of Aggregates Based on Shape We know that aggregate is derived from naturally occurring rocks by blasting or crushing etc., so, it is difficult to attain required shape of aggregate.

Quantity Of Cement, Sand, & Aggregates For 1000 sq ft Slab

To calculate the quantity of cement, sand, and aggregates required for a flat slab first we need to calculate the volume. Area of flat slab = 1000 sq.ft =93 sq. m. The minimum thickness provided for the slab is 150 mm. ( According to IS 456) 150 mm = 0.15 metres. Hence Wet volume = Area of slab x Thickness of slab.
