How to make rate analysis for cement mortar

Mortar is applied to retain the various building materials like brick or stone jointly. It is developed with a dense mixture of water, sand, and cement. The role of water is to moisturize the cement and maintain the mix organized. The water to cement ratio is greater in mortar as compared to concrete so that its bonding element can be developed.

Good mortar plays a vital role in all brick or block walls as it ties the units collectively as well as allows to bear the provided weight on the wall and blocks the joints to arrange for a weatherproof wall. It is essential to utilize good materials for developing mortar to get superior result.

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.

Rate analysis for cement mortar requires calculation of materials for cement mortar is required for making rate analysis of cement mortar i.e. quantity of cement and sand essential for 1m3 with different ratios like CM 1:2, 1:4, 1:6, 1:8 etc. Therefore, initially the quantity of cement and sand should be calculated for 1m3 of cement mortar.

1.3m3 of cement and sand is necessary for creating 1m3 of wet cement mortar because of existence of voids in sand in dry state. So, cement and sand quantity is computed for 1.3m3 of cement mortar.

Computation of Materials for Cement Mortar - Given below, the detailed phases for estimation of quantity of cement and sand for cement mortar:

Suppose, it is required to estimate quantity of cement and sand for CM 1:X, where, 1 denotes proportion of cement and X denotes proportion of sand. Then, quantity of cement is computed as:

Quantity of cement =How to make rate analysis for cement mortar

So, with the above formula, we get the quantity in volume. To estimate the quantity of cement in number of bags, we have to divide it by volume of cement of one bags. The volume of one bag of cement is 0.0347 m3.

So, number of bags of cement =How to make rate analysis for cement mortar

Quantity of sand =How to make rate analysis for cement mortar
As for instance, for a ratio of CM 1:4,
Quantity of cement in bags = How to make rate analysis for cement mortar =7.492 bags
Quantity of sand = How to make rate analysis for cement mortar = 1.04 m3 of sand.
