Composition of cement Penn State Engineering

Composition of cement. Introduction Portland cement gets its strength from chemical reactions between the cement and water. This is a fluxing agent which reduces the melting temperature of the raw materials in the kiln (from 3,000 o F to 2,600 o F). It hydrates rapidly, but does not contribute much to strength of the cement paste.
