MANUFACTURING OF CEMENT funscience

It has the property of setting into hard mass after mixing with water in required amount. It is also known as Portland cement because after setting into hard mass it resembles with the rocks found in Portland in United Kingdom. It is fine grey powder which is made from limestone and clay. The chemical formula of cement is CaO.Al 2 O 3.Fe 2 O 3

Cement History of cement Britannica

Cement Cement History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of 2,000 years ago and of subsequent construction work in western Europe.

Hydration of Portland Cement Pennsylvania State University

Portland cement is a hydraulic cement, hence it derives its strength from chemical reactions between the cement and water. The process is known as hydration. Cement consists of the following major compounds (see composition of cement): Tricalcium silicate, C 3 S; Dicalcium silicate, C 2 S; Tricalcium aluminate, C 3 A;

How Cement Is Made Portland Cement Association

Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients.
