how much cement,sand,aggregate will use for 1 cum in ratio of
1:2:4.

Answer Posted / lakshmanarajan

The Ratio is 1:2:4 Total = 7

Ingredients of this Mixture is = 1.57

So the qty of Cement is = (1/7) x 1.57 = 0.224 cum

Volume of cement in i cum = 1440kg

therefore required cement = 1440 x 0.224 = 322.56kg

Weight of 1 cement bag is = 50 kg

so 322.56/50 = 6.45Bag

Add 5% for wastage = 6.45 x (5/100) = 6.77 bag required

Qty of Sand = (2/7) x 1.57 = 0.448 cum (1cum = 35.31 cuft)

convert cum to cuft = 0.448*35.31 = 15.18 cuft

Sand is available in unit,so 1 unit = 100 cuft

So required qty of sand is = 15.18/100 = 0.151 unit require

Qty of Aggregate = (4/7) x 1.57 = 0.89cum

Convert cum to cuft = 0.89 * 35.31 = 31.42cuft

sand & Aggregate also available in unit

so above the same as aggregate = 31.42/100 = 0.314 unit require
