How To Calculate Quantity Of Cement, Sand And Water In Mortar of 1:4

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 = (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 cement contains 50 kg of cement

Number of bags = 383.04 kg /50 = 7.661 Nos 

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 35.314 = 37.574 CFT

Density of sand = 1920 kg/m3

weight of the sand = 1.064 m3 x 1920 kg/m3 = 2042.88kg => 2.0428 ton.

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 (lit.)
