Cement is commonly mixed with aggregates to form other substances like mortar or concrete, meaning it can be used to bind objects together like the mortar connecting the bricks in a wall or to create a solid structure itself in the …
Functions of Cement and Aggregate in Concrete
The functions of constituents in concrete include cement filling voids and binding aggregates, aggregates providing volume and stability, and water aiding in adhesion, workability, and hydration of cement. Three types of concrete based on unit weight are normal-weight concrete (2400 kg/m3), lightweight concrete, and heavyweight concrete.
4.2 Cement Concrete, Constituents and Uses
The cement used for the manufacture of concrete shall be as fresh as possible. Cement stored more than two months from the date of manufacture should either be rejected or be used only after satisfactory test results. ...

What is Cement Hydration? Phases & It's Importance| UltraTech Cement
2. Binding Agent. During cement hydration, cement acts as a glue, binding aggregate particles together. This reaction ensures the cohesion of various types of stones and sand within the concrete, which is critical for maintaining the integrity and shape of the constructed form, regardless of the size and complexity of the project. 3.
Bulk cement
In the most general sense of the word, cement is a binder, a substance that sets and hardens independently, and can bind other materials together. The word "cement" traces to the Romans, who used the term opus caementicium to describe masonry resembling modern concrete that was made from crushed rock with burnt lime as binder.
Concrete Without Gravel
Cement is a dry powder and is one of the ingredients in concrete. It helps bind the sand and aggregates together to form concrete. Concrete is made from mixing cement, sand, gravel, and water. A simple mixing ratio to make concrete is 1 part cement to 2 parts sand to 3 parts gravel. Mix with enough water to make a workable mixture.
