**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

It was very simply explained and can comes to aid for field engineers. But the crux of this calculation is finding the voids, here i will explain you a simple and useful way to find the voids in sand.

Take a small container with uniform shape from bottom to top(say a dia of 15cm) and measure the depth of the container say X, now fill the container with sand using a trowel. After the container was filled completely, start pouring water and tap the sand with 12 mm rod uniformly all over the container till the water reaches the top of the container. Allow the sand in the container to settle for 10 minutes, now measure the distance above the sand and upto the top of the container say Y. Now we can get the percentage of voids with this simple formula (100/X)*Y.

Once we get the voids percentage we can calculate the cement and sand required for various cement mortars.
