# How to Calculate Quantity for Cement , Sand & Aggregate in Column

In this video lecture today I will teach you that how you can find the quantity of materials in concrete for Column, Like Cement , Sand and Crush. this is the important topic for all civil engineers which want to know about quantity survey.

We will use here M20 Grade of Concrete

M20  =1 : 1.5 : 3

Sum of Ration = 5.5

Volume of Column  =0.27 cu.m

Now Converting wet volume to dry

Dry volume  = wet volume x 1.54

Dry volume  = 0.27 x 1.54 = 0.4158 cu.m

Now find the volume of Cement = 1 / 5.5 x dry volume

Cement Required  = 1 / 5.5 x 0.4158 = 0.0756 cu.m

Cement Bags Required = Volume of Cement  / Volume of one bag cement

0.0756 / 0.0347 = 2.17 No’s of Bags

Volume of Sand = 1.3 / 5.5 x Dry volume of concrete

Volume  of Sand = 1.3 / 5.5 x 0.4158

Sand Required    = 0.1134 cu.m

Volume of Aggregate = 3 / 5.5 x 0.4158 =  0.2268 cu.m
