**QUANTITY OF CEMENT & SAND CALCULATION IN MORTAR**

Quantity of cement mortar is required for rate analysis of brickwork and plaster or estimation of masonry work for a building or structure. Cement mortar is used in various proportions, i.e. 1:1, 1:2, 1:3, 1:4, 1:6, 1:8 etc.

**Calculation of quantity of cement mortar in brickwork and plaster:**

For the calculation of cement mortar, let us assume that we use 1m^{3} of cement mortar. Procedure for calculation is:

1. Calculate the dry volume of materials required for 1m^{3} cement mortar. Considering voids in sands, we assume that materials consists of 60% voids. That is, for 1m^{3} of wet cement mortar, 1.6m^{3} of materials are required.

2. Now we calculate the volume of materials used in cement mortar based on its proportions.

Let’s say, the proportion of cement and sand in mortar is 1:X, where X is the volume of sand required.

Then, the volume of sand required for 1:X proportion of 1m^{3} cement mortar will be

3. Volume of cement will be calculated as:

Since the volume of 1 bag of cement is 0.0347 m^{3}, so the number of bag of cement will be calculated as:

**Example:**

For cement mortar of 1:6, the quantity calculated will be as below:

Sand quantity:

Quantity of cement (in bags):

Volume of cement =

There number of bags required = = 6.58 bags.

thanks friend

Aashi Ashiq

thanks for this….how we can find out the quantity of sand and cement in 30m2 plastered area or 6m3 brick work?

Shihab Np

30m2 plaster= 144kg cement, 21cft sand
