But if the value is greater than 3.19 it means cement is containing greater amount of moisture content which will affect the workability and strength of concrete. This is why we need to calculate the correct value of specific gravity of cement before using it in ...Relative density - WikipediaRelative 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 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" is often preferred in ...SPECIFIC GRAVITY TEST OF CEMENT – we civil engineersApr 06, 2018· Specific gravity of cement is tested in order to know the various atmospheric effects on the moisture content of a cement. Generally nominal Mix design is based on the value of specific gravity of cement as 3.15. The value will change over time if the cement is exposed to various weather conditions. So it is essential to determine the specific ...Gravity - WikipediaGravity (from Latin gravitas, meaning 'weight'), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light —are brought toward (or gravitate toward) one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.The gravitational attraction of the original gaseous matter ...
