Mar 31, 2019 · In general, To calculate the specific gravity of material, we use water. But in cement, we use kerosene for finding specific gravity in it. The reason behind this, cement hydrates and forms calcium oxide when it reacts with water. Cement won't show any reaction when it mixed with kerosene. Is cement a density code? Specific Gravity of Cement ...

Get Price#### Relative density

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or °F); for gases, the reference is air at room temperature (20 °C or 68 °F). ). The term "relative density" is often preferred in ...

A cement is a binder, a substance used in construction that hardens, hardens and adheres to other materials to join them together. Cement is rarely used on its own, but to bond sand and gravel. The cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. First, density is the ratio of mass to volume. So it can be indied in terms of kg / m 3 ...
