Cement Amp Concrete Basics Faqs

Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone the paste is water and portland cement. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass.

The Cement Kiln

Wet process kilns. The original rotary cement kilns were called wet process kilns. In their basic form they were relatively simple compared with modern developments.
