Abstract

The invention discloses an environment-friendly building material with high strength. The environment-friendly building material comprises the following raw materials in parts by weight: 20 to 25 parts of fly ash, 13 to 18 parts of calcium stone powder, 17 to 21 parts of perlite rock powder, 7 to 10 parts of benzenesulfonyl hydrazide, 21 to 26 parts of polyvinyl alcohol fiber, 100 to 110 parts of regeneration aggregate, 70 to 80 parts of silicate cement, and 3 to 6 parts of methyl cellulose. The invention also discloses a preparation method of the environment-friendly building material with the high strength. The prepared environment-friendly building material has the characteristics that the strength, hardness, abrasion-resistant property, impact flexibility-resistant property, anti-freezing property and water-resistant property are good; the building waste is used as raw material, and is changed into valuable material, so that the problem of resource lack is relieved, and the practicality is strong.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-strength environment-friendly building material and a preparation method thereof. Background technique [0002] Building materials are the basis of construction engineering, and concrete is the most widely used building material. Its main components include cement, admixtures and aggregates. It is hardened after adding water and mixing. It has the advantages of simple process and fire resistance. With the large-scale urban construction and industrial development, the construction waste generated during the demolition and construction of construction projects is also increasing significantly year by year. The so-called construction waste is mainly composed of inorganic substances such as broken concrete, broken bricks and tiles, broken sand and gravel. Its chemical composition is silicate, oxide, hydroxide, carbonate, sulfide and sulfate. It has very good stren...
