How to calculate cement qty of M10, m20, m25 ?
I got the formula but I lost it.

Answer Posted / jayaraaj.arumugam

Dear Friend,

in M10 grade ratio 1:4:8 using 40mm aggregate
*40mm agg - 1.52; 20mm agg - 1.57 volume of ingredient*

since 1+4+8 = 13
aggre - 8/13 * 1.52 = 0.935
sand - 4/13 * 1.52 =0.467
cement - 1/13 *1.52 =0.1169*1440=168.36/50 = 3.37 bags

Is This Answer Correct ?    31 Yes 22 No
