Since concrete is the most used building material, chippings which acts as coarse aggregates is one of the most important building elements which has cost implications if not well optimized. You may want to do a check of the cement quantity for your building project. Kindly follow the process below in this case:
Assumptions:
Slab area= 180 square meters
Slab thickness= 150mm (6 inches)
Length of beam = 130 meters
Slab chippings calculation
Chippings required= Volume of concrete x tonnes of chipping per cubic meter
Chippings per cubic meter of concrete is 1.7 to 2 tonnes
Volume of slab= Slab Area x Slab thickness
Slab area= 180 sq.m
Thickness used= 150mm
Volume of slab= 180 x .15m
27m3
Volume of beams= Total length of beams x width of beam x Height of beam
=130m x 0.225m x 0.3m= 8.8 m3
Total volume= 37.9 cubic meters
Chippings required= 37.9 cubic meters x 1.7 tonnes per cubic meter
=64.4 metric tonnes
