Abstract

The invention discloses an environment-friendly brick with good pressure resistance. The environment-friendly brick comprises the following raw materials in parts by weight: 60-80 parts of shale rock,15-25 parts of broken stones of building solid waste and gravels, 6-10 parts of ordinary Portland cement No. 325, 1-3 parts of a liquid admixture and 1-3 parts of water. The invention further provides a preparation method of the environment-friendly brick with good pressure resistance. Quartz sand mud has the characteristics of fineness, proneness to hardening and high possibility of dispersion and decomposition when meeting water, so the quartz sand mud should be observed in the stirring process; the quartz sand mud is fully stirred and ground into powder, the gravels and cement are added inproportion and stirred, then the liquid admixture is added and stirred, and then pressing can be conducted. A molded product has no obvious cracks on the surface, and is compact in structure and freeof a particle shape, and the appearance of the product conforms to a production standard. The compression resistance of the product is 21.6 MP.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly materials, and in particular relates to an environment-friendly brick with good compression resistance and a preparation method thereof. Background technique [0002] Manufactured by using fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, industrial waste, waste incineration slag, etc. (one or more of the above raw materials) as the main raw materials without high-temperature calcination A new type of wall material is called environmental protection brick. [0003] In the prior art, the heat resistance and pressure resistance of the environmental protection brick are poor, so it is urgent to develop an environmental protection brick with good compression resistance to solve the problems in the prior art. Contents of the invention [0004] The purpose of the present invention is to provide an environment-friendly brick with good compression resi...
