### Quantity of Mortar:-

Volume of mortar= 1 m³

Mix Ratio –> 1:6

**Dry volume of mortar = Wet volume x ****1.33**

Dry Volume = 1.0 m³x 1.33 = 1.33 m³

### Quantity of cement:-

**Quantity ****of Cement = (Dry Volume of mortar x Cement ratio) / (Sum of the ratio****)**

∴Quantity of cement = (1.33 x 1) /(1+3)=0.3325 m³

** Density ****of Cement = ****1440 kg/m****³**

∴ Weight of Cement = 1440 x 0.3325 = 478.8Kg

**1 ****bag of cement contains 50 kg of cement **

∴ Number of bags = 478.8 Kg/50 = 9.576 No’s

### Quantity of Sand:-

** ****Cement ****: Sand :: ****1:3**

**Quantity of Sand = Quantity of Cement x 3**

∴ Quantity of Sand = 0.3325 m³ x 3= 0.9975 m³

**1 m³=35.3147 ****Cubic Feet (CFT****)**

∴ Quantity of sand = 0.9975 x 35.3147 = 35.226 CFT

**Density of sand = 1920 kg/m****³**

∴ Weight of the sand= 0.9975 m³ x 1920 kg/m³ = 1915.2 kg =>1.9152 tonnes

**Quantity of water:-**

**Water ****cement ratio = weight of ****water/weight ****of ****cement**

**W/C—>****0.50**

** weight ****of water = (weight of ****cement)x(w/c ****ratio)**

∴ Weight of water = 478.8 kg x 0.5 =239.4 kg (Litre)
