Abstract
Millions of tons of waste by-products from Texas coal burning plants are produced each year. Two common byproducts are the fuel ashes and calcium sulfate (gypsum). Fuel ashes result from the burning of coal. Gypsum is a byproduct of the air purification system, called Flue Gas Desulfurization (FGD). Abatement of these waste products is a growing concern, not only for the industry, but the environment as well. It is possible to produce a gypsum brick unit that can meet the engineering properties required by the Americans Society of Testing Materials (ASTM) standards by using these by-products. This can be accomplished at a cost less than the least expensive common fired clay brick that is used in construction operations. The gypsum brick can be manufactured using established methods that are currently in operation.
