Cement
![Cement is usually a powder which is being mixed with other materials and water. Many types of cement powder can cause allergic reactions upon skin contact and are irritating to skin, eyes, and lungs, so handlers should wear a dust mask, goggles, and protective gloves, unlike the worker pictured here[1][2][3]](/Images/godic/202501/03/USMC-110806-M-IX060-1483030.jpg")

A cement is a binder, a substance used in construction that sets and hardens and can bind other materials together. The most important types of cement are used as a component in the production of mortar in masonry, and of concrete- which is a combination of cement and an aggregate to form a strong building material.
