Let us go through the procedure to calculate the volume & weight of the standard concrete cubes used in the lab. testing.
Given data:
Dimension of the cube
= 150mm. × 150mm. × 150mm.
= 0.15m. × 0.15m. × 0.15m.
1. Volume of the cube is calculated by the formula
= [length × breadth × height]
In any cube, all the 3 sides are equal
i.e. length = breadth = height = s
So, the volume of the concrete cube
= [0.15m. × 0.15m. × 0.15m.]
= 0.003375 CUM.
2. The weight of the concrete cube
= [density × volume.]
As you know, the density of concrete =2400kg. / CUM.
The weight of the concrete cube
= [2400 kg./ CUM × 0.003375 CUM]
= 8.1kg.
Note:
1. The density of RCC = 2500kg./CUM &
2. The density of PCC = 2400kg. / CUM.
The concrete cube does not contain reinforcement. So, its density will be 2400 kg / CUM.
