HOW TO ESTIMATE YIELD OF CONCRETE FOR VOLUME BATCHING
Aug 12, 2015 · Estimate the yield of concrete per bag of cement for a concrete mix of proportion (1:2:4). By Rule of Thumb. A bag of cement containing 50 kg of cement is considered to have a volume of 0.035 m 3. Therefore a = 0.035 m 3. Then volume of sand becomes, b = 2*0.035 m 3. And volume of coarse aggregate becomes, c = 4*0.035 m 3. So yield of concrete ...
