Abstract

The invention relates to a wall brick for buildings. The wall brick is formed by mixing clay, an auxiliary material, aluminum ash and iron mine waste residue with water and firing, wherein weights of the auxiliary material, the aluminum ash and the iron mine waste residue respectively account for 30-50%, 10-13% and 7-9% of the weight of the clay; and the auxiliary material is formed by mixing rosin, calcium carbonate particle with the fineness of 8-20 meshes and carbon powder in the weight ratio of 1:(30-50):(5-10). The wall brick disclosed by the invention has the advantages that the iron mine waste residue obtained after iron mine excavating and the waste aluminum ash produced in aluminum electrolysis are adopted to produce the wall brick, so that the clay consumption is reduced and the iron mine waste residue and the aluminum ash are fully utilized; the produced wall brick is very high in internal porosity to ensure that the weight is reduced, but the strength is greatly improved under the action of the internal sintering phase produced during the stirring; and in the meantime, the surface and the interior of the wall brick are provided with a certain gap, so that the wall brick has a certain function of absorbing noise.

Description

technical field [0001] The invention relates to building materials used in the construction field, in particular to a building wall brick and a preparation method thereof. Background technique [0002] In the prior art, the production of wall bricks used for building houses generally has the following steps: digging out the soil and mixing it with water to form it, and sending the green body into a kiln for firing after drying in the shade. Due to the rapid development of the real estate industry, the demand for wall tiles has also increased rapidly. However, a large number of wall bricks are fired with clay, which leads to the reduction of cultivated land resources, and the strength of the produced wall bricks is poor, and it is easy to be damaged if it bears a large weight. Contents of the invention [0003] In order to solve the problem of low strength of wall bricks in the prior art, the present invention provides a building wall brick and its preparation method, whic...
