Web28 de mar. de 2024 · Just as a reminder, it goes as follows: weight = volume × density. For clarity's sake, let's go through a quick example. Let's say we have 15 cubic meters of Portland concrete. The density of this type of concrete in kilograms per cubic meter is 2,300, so the calculation goes as follows: weight of concrete = 15 m³ × 2,300 kg/m³ = … WebTag: Normal-Weight Concrete Portland-Cement Concrete Portland-cement concrete is a mixture of portland cement, water, coarse and fine aggregates, and admixtures proportioned to form a plastic mass capable of being cast, placed, or molded into forms that will …
