FAQ's

What is Portland cement?

Portland cement is a manufactured product made in several steps. First we carefully blend limestone with shale or clay and iron to a desired chemical composition. We then grind it to a fine powder called raw meal. We feed the raw meal to a rotary kiln that is fired by coal, natural gas or another high energy fuel. The temperatures in the kiln reach about 2,800° F. At these temperatures the raw meal undergoes a chemical reaction and forms a new product called clinker. The clinker is mixed with about 5% gypsum and ground to a fine powder called Portland cement.
