Process for making bricks by utilizing solid construction wastes

Abstract

The invention discloses a process for making bricks by utilizing solid construction waste, and relates to the technical field of making bricks by utilizing solid construction waste. The process comprises the following steps: S1, classifying and removing impurities; S2, solid waste crushing; S3, solid waste screening; S4, stirring and mixing the materials; S5, preparing a blank; S6, pressing to prepare a blank; S7, roasting molding. According to the process for making the bricks by utilizing the solid construction wastes, the solid construction wastes are used as a main raw material, the process has the advantages of low cost, economy and environmental protection, and the production process is simple and suitable for large-scale production; solid construction wastes can be classified through the step of classifying and impurity removing, mutual mixing of the solid construction wastes is avoided, and therefore proportioning and mixing of various subsequent solid waste are facilitated; the solid construction waste mixed material prepared from coal gangue, fly ash, coal cinder and blast furnace slag according to a mass ratio of 1: 1.2: 0.5: 0.5 has good thermal insulation performance and mechanical properties, and is suitable for the field of brick making so that the brick body can meet the requirements of national standards on wall bearing materials.

Description

technical field [0001] The invention relates to the technical field of brick making from solid construction waste, in particular to a brick making process using solid construction waste. Background technique [0002] Solid waste construction materials refer to various solid wastes such as coal gangue, fly ash, coal cinder, blast furnace slag, steel slag, etc., which have the components and properties required for construction materials, and can be used to make construction materials. Its phase composition is relatively stable, its chemical composition is similar to that of building materials, and it has potential activity. In order to solve the increasing shortage of resources, the problem of energy shortage and the growing demand for building materials in our country, solid construction waste can be used to make bricks. Most industrial solid waste has the potential to produce building materials, which can save costs as raw materials for building materials , create higher e...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a process for making bricks by using solid construction waste, which solves the problem of making bricks from solid construction waste in the above-mentioned background technology due to the performance difference between various solid construction wastes. Large, without sorting treatment before brick making, the resulting mixture is prone to unstable quality, and there is no screening step in the raw material processing process, the obtained solid waste raw material particles are uneven in size, which cannot meet production needs. And the corresponding ingredients are not added in the brick making process, the quality of the finished bricks is not good, and the comprehensive performance and strength cannot meet the existing load-bearing requirements
