The application discloses an environment-friendly high-strength granite-imitated super-thick
brick and a preparation method thereof. The
brick comprises 5-30 parts of clay, 5-60 parts of aluminum ash, 1-20 parts of sand-shaped
brick slag waste, 1-20 parts of sand-shaped granite
slag waste and 1-20 parts of sand-shaped glass
slag waste. The thickness of the brick is 30-60 mm, and the water
absorption rate is 2-8%. The environment-friendly high-strength granite-imitated super-thick brick utilizes the gap between the sand-shaped waste and the clay, so that the
green body has a good exhaust passage during the
sintering process, thereby avoiding the technical problem that the
green body is too thick, the bubbles cannot be exhausted, and product defects such as black core, bubbles and collapse are easily formed. Meanwhile, the aluminum ash contains a large amount of aluminum
oxide,
silicon dioxide and
magnesium oxide and other substances, and forms a super-high-strength
composite crystal phase
system with other waste and clay, so that the product has high compressive and destructive strength, is not easy to break, maintenance cost is reduced, and the service life of the product is prolonged.
