What is Cement?
Cement is a fine gray powder that is mixed with water and other substances to make mortar
or concrete. It is a key building material in both residential and commercial construction
work.
CEMENT VS. CONCRETE
The words cement and concrete are often used interchangeably. However, cement is actually
an ingredient of concrete, not the final product. Cement is important because it binds, or
holds, the concrete mix together, giving it strength
Cement is a construction material that has cohesive and adhesive properties in the
availability of water. Joseph Apsdin of Uk is a First person who invent Cement in 1824 A.D.
He named the cement i.e. Portland cement because the natural stone that occurs for the
manufacturing of cement is from the Place called Portland of England.
Raw Material used in Cement
a) Limestone (Caco3
, b) Sand (Sio2)
c). Stale clay (SiO2, Al2O3, Fe2O3)
Chemical Components
a). Calcium (Ca)
b). Silicon (Si)
c). Aluminum (Al)
d). Iron (Fe)
Chemical Components of Cement
There are two components i.e. Calcareous and Argillaceous components.
Calcareous Components (Lime CaO)
a). Limestone
b) Chalk
c) Marble shells
d) Lime sludge
Argillaceous Components (SiO2, Al2O3, Fe2O3)
a) Clay
b) Shale
c). Rock
d) Blast furnace slag
e) Marl
