What is cement used for

Cement is used for sticking hard objects together so that they can stiffen and it would be difficult to break. For example: Cement is used for bricks to stick together to make houses

A cement is a binder. It is a substance that sets and hardens and can bind other materials together. Cement is usually in a form of powder which is being mixed with other materials and water. The most important uses of cement are as a component in the production of mortar in masonry, and of concrete, a combination of cement and an aggregate to form a strong building material. Cements used in construction can be characterized as being either hydraulic or non-hydraulic, depending upon the ability of the cement to set in the presence of water.
