Question

It is known that after the concrete is adjusted by trial mixing, the amount of various materials is: cement 3.10kg, water 1.86kg, sand 6.24kg, crushed stone 12.8kg, and the apparent density of the mixture is 2500kg ∕ m^3.How much is the amount of per cube concrete material?

Answer 1

To calculate the amount of material per cubic meter of concrete, divide the mass of each material by the apparent density of the mixture.

Step-by-step explanation:

To calculate the amount of material per cubic meter of concrete, we need to divide the mass of each material by the apparent density of the mixture. Given that the mass of cement is 3.10kg, the mass of water is 1.86kg, the mass of sand is 6.24kg, and the mass of crushed stone is 12.8kg, and the apparent density of the mixture is 2500kg/m^3, we can calculate:

Amount of cement = mass of cement / apparent density = 3.10kg / 2500kg/m^3 = 0.00124m^3

Amount of water = mass of water / apparent density = 1.86kg / 2500kg/m^3 = 0.000744m^3

Amount of sand = mass of sand / apparent density = 6.24kg / 2500kg/m^3 = 0.002496m^3

Amount of crushed stone = mass of crushed stone / apparent density = 12.8kg / 2500kg/m^3 = 0.00512m^3
