Concrete
Mix Quantities Calculation

Concrete mix= 1:1.5:3

Total volume= 1+1.5+3=5.5

Wet Volume= 1m3

Dry volume = 1.54*1=1.54m3 (54%
increases)

Cement:

Quantity of cement in cubic meters= <img alt="" width="106" height="30">

Quantity of cement in kg= <img alt="" width="163" height="30"> (Density
of cement = 1440 kg/m3)

Total number of
cement bags required= <img alt="" width="94" height="30">bags

Sand:

Quantity of sand in
cubic meter=<img alt="" width="115" height="30">

Quantity of sand in kg=
<img alt="" width="159" height="30"> (Density of sand = 1500 kg/m3)

Quantity of sand in
cubic feet= <img alt="" width="219" height="30">

Coarse
Aggregates:

Quantity of
aggregate in Cubic meter=<img alt="" width="106" height="30">

Quantity of
aggregate in kg =<img alt="" width="159" height="30"> (Density of aggregate = 1450 kg/m3)

Quantity of
aggregate in cubic feet= <img alt="" width="210" height="30">

Water:

For the concrete mix,
30 litres of water per 50Kg cement should be used.

Total amount of water
needed= <img alt="" width="180" height="30">
