ANALYSE AN RCC SLAB FOR A ROOM MEASURING 1 METRE X 1 METRE HAVING SLAB THICKNESS EQUAL TO 0.15 METRE

Solution:

Volume =1 Metre X 1 Metre X 0.15 Metre

Volume=0.15 Metre

Or, Dry Volume = 0.15 Cubic Metre

Wet Volume=Dry Volume X 1.54

Wet Volume=0.15 Cubic Metre X 1.54

Wet Volume=0.231 Cubic Metre

Mortar Ratio=1:2:4 (Given)

Sum of Ratios=1+2+4=7

Cement Required=1÷7 X 0.231 CUM

Cement Required=0.033 CUM

Cement Required=0.033 X 28.8

Cement Required=0.95 Bags

Remember 28.8 Bags of Cement Are Required in 1 Cum

Sand Required=2÷7 X 0.231 CUM

Sand Required=0.066 CUM


Aggregates Required=4÷7 X 0.231 CUM

Aggregates Required=0.132 CUM

Steel

Assume 1% of  Dry Volume is The Volume of Steel Required

Volume= 1÷100 X 0.231

Volume=0.00231 Cubic Metre

Density=Mass÷Volume

Mass=Density X Volume

Mass=7850 Kg/M³  X  0.00231 M³

Mass=18.13 Kgs

Steel =18.13 Kgs

Binding Wire

Remember 100 Kgs of Steel Requires 1 Kg of Binding Wire

Binding Wire= 1÷100 X 18.13

Binding Wire=0.18 Kgs
