It is known that the water binder ratio of concrete is 0.5, the water consumption of concrete is 180kg, the sand ratio is 33%, assuming that the apparent density of concrete is 2400KG / m, try to calculate the amount of each material (without mineral admixtures and chemical admixtures)
Cement: 180 divided by 0.5 equals 360 kg
Water: 180 kg
Sand: (2400-180-360) * 0.33 = 613.8kg
Stone: (2400-180-360) * 0.67 = 1246.2kg
Water binder ratio: water / cementitious material
Sand ratio: weight of sand / aggregate
Apparent density; total weight of all materials (cement + water + aggregate)
Aggregate: (sand + gravel)
