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/m³
∴ 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)
