Antique Brick Produced from Marble Waste and Its Production Technology

Abstract

The invention discloses an archaized brick produced through marble waste and a production process of the archaized brick. The archaized brick is prepared from the following raw materials in parts by weight: 30-50 parts of feldspar, 10-20 parts of kaoline, 5-10 parts of high-temperature sand, 30-40 parts of low-temperature sand, 6-8 parts of black clay, 8-10 parts of bentonite, 3-6 parts of attaclay, 20-30 parts of hard clay, 10-15 parts of bauxite, 1-3 parts of white clay and the marble waste, wherein the marble waste accounts for 10-20 wt% of the total materials. According to the obtained archaized brick, the water absorption rate is 2% or below, the bending strength can reach 27 MPa or above, the excellent abrasion resistance level can be reached, and radioactivity meets the requirements; and meanwhile, by doping the marble waste to produce the archaized brick, the waste is turned into wealth, the mechanical strength of the archaized brick is guaranteed, the strength and water absorption performance of the archaized brick are not affected, good heat preservation and insulation performance can further be achieved, and environment-friendly industrial production and sustainable development are achieved.

Description

technical field [0001] The invention relates to the technical field of antique brick production, in particular to an antique brick produced by using marble waste and a production process thereof. Background technique [0002] Marble is a metamorphic rock formed by the original rocks in the crust through the action of high temperature and high pressure in the crust. The internal force of the crust promotes the process of qualitative changes in the original various rocks. Qualitative change refers to the change in the structure, structure and mineral composition of the original rock, and the new rock type formed after qualitative transformation is called metamorphic rock. Marble is mainly composed of calcite, limestone, serpentine and dolomite, and its main component is calcium carbonate. Marble floor tiles have attracted the attention of consumers with their gorgeous appearance and very practical features, and are a commonly used stone for architectural decoration. During p...

Problems solved by technology

During production and use, marble is often cut into different shapes and sizes according to needs, and a lot of corner waste will be generated during the cutting process. If the waste is discarded directly, it will have to be shipped out at an economic cost, and in the process of stacking may also damage the environment
