Calculation of quantity of cement mortar in brickwork

and plaster:

For the calculation of cement mortar, let us assume that we use1m3of cement mortar. Procedure for calculation is:

1. Calculate the dry volume of materials required for

1m3 cement mortar. Considering voids in sands, we assume

that materials consists of 60 voids. !hat is, for 1m3 of wet

cement mortar, 1.6m3 of materials are required.

". #ow we calculate the volume of materials used in cementmortar $ased on its %ro%ortions.

&et's say, the %ro%ortion of cement and sand in mortar is 1:(,

where ( is the volume of sand required.

!hen, the volume of sand required for 1:( %ro%ortion of

1m3 cement mortar will $e

3. )olume of cement will $e calculated as:

*ince the volume of 1 $ag of cement is 0.03+ m3, so the

num$er of $ag of cement will $e calculated as:

Example:

For cement mortar of 1:6, the quantity calculated will $e as
