(1) ACID ALKALI RESISTANT BRICKS
For masonry constructions and flooring that are vulnerable to acid attack, lining chambers and towers in chemical plants, lining sewers conveying industrial effluents, and to avoid surface deterioration by acids other than hydrofluoric and perchloric acids, acid resistant bricks are employed.
Bricks that are acid resistant are created by vitrifying raw materials, such as clay with a proper composition that contains little lime and iron, feldspar, flint, or sand, at high temperatures in ceramic kilns.
Chemically resistant mortars are typically used to install acid resistant bricks. They come in a variety of sizes and forms and are bedded and joined with cement that is acid proof. The cements employed are dependent on temperature and chemical conditions up to their prescribed limits.
