How do you determine the Specific gravity of cement?
Answer:
Cement is often sold as a powder that is blended with sand, aggregate (gravel or crushed stone), water, and other ingredients to produce concrete. Due to the fact that cement is often a powder, it is difficult to obtain a standard figure for the specific gravity of cement. Furthermore, because cement is rarely used on its own, knowing the specific gravity of the material is not particularly beneficial in most cases.
In this case, “What is the typical density of concrete?” is a more appropriate question. As a matter of thumb, standard cured concrete has a density of around 150 pounds per cubic foot, according to the manufacturer. This includes the weight of the cement, sand, and aggregate, as well as the amount of water that chemically bonds with the cement to make the concrete… Because water weighs approximately 62.4 pounds per cubic foot, concrete weighs approximately 2.4 times as much as water. As a result, concrete has a specific gravity of around 2.4. If you took cement and mixed it with water, you would end up with a hard lump of useless cement that had a specific gravity of between 2 and 2.4, which was not useful.
