🕑 Reading time: 1 minuteRate analysis for cement mortar requires estimation of materials for cement mortar, i.e. quantity of cement and sand required for 1m3 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 1m3 of cement mortar. For 1m3 of wet cement mortar, 1.3m3 of cement and sand is required, due to presence of voids in sand in dry state. So, cement and sand quantity is calculated for 1.3m3 of cement mortar.
