Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...

Cement density:- generally density of cement is around 1440kg/m3 or it is measured in other unit- their density is 1.440 in g/cm3, 94 in lb/ft3 and 14.40 in kn/m3. The cement mixed with fine aggregate produces cement mortar for masonry, or with sand and gravel produces concrete. Ans. 1440 kg/m3 is density of cement.
