Abstract

The non-granular environment-friendly brick is prepared from the following raw materials in parts by weight: 60 to 70 parts of quartz sand mud, 21 to 25 parts of building solid waste broken stones andgravels, 10 to 14 parts of 425 # ordinary Portland cement, 1 to 3 parts of a liquid admixture and 1 to 3 parts of water. The invention further provides a preparation method of the non-granular environment-friendly brick. In the invention, the quartz sand mud has fine characteristics, is easy to harden and is easy to disperse and decompose when meeting water, so that the quartz sand mud should beobserved and fully stirred and ground into powder in the stirring process, gravels and cement are added in proportion and stirred, and then the liquid admixture is added and stirred to be pressed. Andthe molded product has no obvious cracks on the surface, has a compact structure and is non-granular in shape, and the appearance conforms to the production standard. And the compression resistance is 21.6 MP.

Description

technical field [0001] The invention belongs to the technical field of environmental protection materials, and in particular relates to a non-granular environmental protection brick 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] The heat resistance of the environmental protection brick in the prior art is poor, so there is an urgent need to develop a non-granular environmental protection brick to solve the problems in the prior art. Contents of the invention [0004] The purpose of the present invention is to provide a non-granular environment-friendly brick and a preparation method thereof. [0005] In order to solve t...
