Composition of cementPenn State College of Engineering

Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration.This is a complex process that is best understood by first understanding the chemical composition of cement.

The Differences Between Cement Concrete and Mortar

Cement is the binding element in both concrete and mortar. It is commonly made of limestone clay shells and silica sand with limestone being the most prevalent ingredient. These materials are crushed and combined with other ingredients (including iron ore) and then heated to about 2 700 F.

White Portland cementWikipedia

Specifications. White Portland cement differs physically from gray cement only in terms of its color. Its setting behavior and strength development are essentially the same as that expected in gray cement and it meets standard specifications such as ASTM C 150 and EN 197. In practice because much white cement is used in pre-cast concrete products it is commonly made to a high-early strength

High Alumina CementComposition Uses Applications

High Alumina Cement. High alumina cement is the same as rapid hardening cement which attains ultimate strength in a short period. Unlike Ordinary Portland cement It contains calcium aluminates instead of calcium silicates. HAC is manufactured from chalk or limestone and bauxite. It contains 35 of Alumina and a balance of lime components.
