I need to make some bedding mortar for laying coping stones on a brick wall
Ive calculated the volume of mortar needed
12m x 0.41m x 0.03m = 0.1476 m3
I buy cement and sand in 25 kg bags and would use 1-4 cement/sand ratio So 125kg would be 1 bag of cement to 4 bags of sand
but how to I equate weight with volume ?
