^{3}for various proportions, i.e., CM 1:2, 1:4, 1:6, 1:8 etc. So, let us first calculate quantity of cement and sand required for 1m

^{3}of cement mortar. For 1m

^{3}of wet cement mortar, 1.3m

^{3}of cement and sand is required, due to presence of voids in sand in dry state. So, cement and sand quantity is calculated for 1.3m

^{3}of cement mortar.

**Estimation of Materials for Cement Mortar:**

**Steps for calculation of quantity of cement and sand for cement mortar:**

^{3}. Therefore, number of bags of cement =

^{3}of sand.

**Estimation of Labour and Tools for cement mortar:**

For 1m^{3}of cement mortar, semi-skilled labour is required for 0.27 days for mixing, unskilled labour for 0.26 for carrying of cement, sand and water. Hire charges for mechanical mixer is taken in lumpsum of can be taken as 0.27 days for mixing 1cum of mortar.

**Rate Analysis of cement mortar:**

Rate analysis of cement mortar requires the rate of cement and sand multiplied with their respective quantity. Cost of labour and tools and tackles for the cement mortar is also calculated. Cost of cement, sand, labour and tools depend on local availability and local rates.
When, quantity of cement, sand, labour and tools are multiplied by its rates, and a contractors profit of 10-20% is assumed, the total sum of the amount is taken as the cost of 1m^{3}of cement mortar, which is shown in the file below.
