Abstract

The invention discloses a preparation process of an environment-friendly durable building material. The environment-friendly durable building material is prepared from the following raw materials in parts by weight: 100 parts of silicate cement, 30 to 40 parts of volcanic ash, 300 to 400 parts of sand, 5 to 10 parts of aggregates, 10 to 15 parts of antifreezing agent, 15 to 20 parts of xanthan gum, 2 to 4 parts of water reduction agent, and 30 to 50 parts of water. The preparation process comprises the following steps: S1, preparing antifreezing agent; S2, preparing a raw material; and S3, preparing a building material. The building material provided by the invention is durable, environment-friendly, high in strength, good in anti-seepage performance, high in cohesive force, long in service life, easy in transportation and construction, and short in construction period.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation process of an environmentally friendly and durable building material. Background technique [0002] Building materials refer to the general designation of engineering composite materials that aggregate aggregates into a whole by cementitious materials, and are one of the most frequently used materials in engineering construction. At present, the building materials we use mainly use cement as the cementitious material, add sand and stone as the aggregate, and add a certain proportion of water to stir it. The performance of building materials will directly affect the firmness of buildings, especially the frost resistance and impermeability of building materials. Therefore, the development of building materials is gradually moving towards environmentally friendly and durable mixed concrete. [0003] CN201811243132 proposes graphite tailings concrete mixture...
