From the perspective of mix proportion analysis, the assumed volume method is generally used to calculate the concrete density, that is, the sum of the masses of each component material in a 1m3 concrete mixture should be equal to the assumed apparent density, and solved together with the sand ratio expression to obtain the amount of coarse and fine aggregates in each cubic meter of concrete.
The assumed apparent density of concrete mixture is generally between 2350-2450kg/m3 (JGJ 55-2011 “Design Specification for Ordinary Concrete Mix Proportion”).
The water cement ratio of high-strength concrete is small, assuming a bulk density of 2350kg/m3 and a slurry ratio.
