As per ratio 1:4:7, how can we calculate the quantity of materials for 1 cum of concreate, pls derive with equation
Answer Posted / snigda
Absolute Volume Method - 1:4:7
Material Wt of material per bag of cement Specific Gravity Calculation Absolute Volume of material
Cement 50 Kgs 3.15 50/(1000*3.15) 0.016
Fine Aggregate 200 Kgs 2.65 200/(1000*2.65) 0.075
Coarse Aggregates 350 Kgs 2.8 350/(1000*2.8) 0.125
Water 25 lts 1 25/(1000*1) 0.025
0.241
Assuming 1% air content 0.00241 Total absolute volume 0.244
Cement per cum of concrete 1/0.244 4 bags/ cum 205 kgs 0.14 cum
Sand per cum of concrete 4/0.244 16 bags/ cum 820 kgs 0.51 cum
Coarse aggregate 7/0.244 29 bags/ cum 1434 kgs 0.80 cum
