Density of Concrete The Physics Factbook Hypertextbook
"Typically, concrete has a density of 150 pounds per cubic foot, which means that a block of concrete that is one foot wide, one foot long, and one foot high would weigh 150 pounds. Water has the density of only 62.4 pounds per cubic foot."Solids and Metals Specific Gravities Engineering ToolBox,The Specific Gravity SG is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference at this point the density of water is at the highest.. Specific gravities SG for common solids and metals can be found in the table below

Specific gravity is the ratio of the weight of a cubic foot of a material to the weight of a cubic foot of water, which is 62.4 pcf. Therefore, the specific gravity of a typical concrete mix is 145/62.4 or 2.32.
Specific Gravity Of General Materials Table CSGNetwork
The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).Specific Gravity of cement or Desnsity of cement , Le ,Every material has its own specific gravity, and it usually ranges between 0.1 – 100. If the specific gravity of the material is less than 1, then that material floats in water. If the material has a specific gravity greater than 1, then it sinks in water.
