What's the Difference Between Cement and Concrete?

Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass. This hardening process continues for years meaning that concrete gets stronger as it gets older. So, there is no such thing as a cement sidewalk, or a cement mixer; the proper terms are concrete sidewalk and concrete mixer.

Specific Gravity of Cement

If the cement has exposed to extreme moisture content then, the specific gravity of cement will differ because of the moisture content present in the pores. Every material has solid particles and pores which may contain water in it. Normally our 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.

Cement Production

The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity.
