**Quantity of Mortar:-**

Volume of mortar= 1 m³

Mix Ratio –> 1:4

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

Dry Volume = 1.0 m³ x 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+4)= 0.266 m³

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

∴ Weight of Cement = 1440 x 0.266 = 383.04 Kg

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

∴ Number of bags = 383.04 Kg/50 = 7.661 No’s

**Quantity of sand:-**

** ****Cement ****: Sand :: 1:4**

**Quantity of Sand = Quantity of Cement x ****4**

∴ Quantity of Sand = 0.266 m³ x 4 = 1.064 m³

**1 m³=35.3147 Cubic Feet (CFT****)**

∴ Quantity of sand = 1.064 x 35.3147 = 37.574 CFT

**Density of sand = 1920 kg/m³**

∴ Weight of the sand= 1.064 m³ x 1920 kg/m³= 2042.88 kg =>2.0428 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 = 383.04 kg x 0.5 = 191.52 kg (Litre)
