Concrete efficient waterproof and compression resistant alloy powder and preparation method thereof

Abstract

The invention provides concrete efficient waterproof and compression resistant alloy powder and a preparation method thereof. The concrete efficient waterproof and compression resistant alloy powder is prepared from the following raw materials in parts by weight: 35 to 60 parts of magnesium iron silicate tailing micro powder, 8 to 12 parts of alumina, 5 to 10 parts of dolomite, 10 to 20 parts of natural mica flake, 3 to 8 parts of magnesium oxide, 3 to 8 parts of zirconium dioxide, 0.5 to 3 parts of graphene oxide powder, 0.5 to 3 parts of perfluororooctyltriethoxysilane and 10 to 15 parts ofmodified nanometer silicon rubber. The invention provides the concrete efficient waterproof and compression resistant alloy powder. The specific weight of the material is similar to that of cement; the separation and water secretion of a concrete mixture can be reduced; the material accumulation effect and the pore structures are improved; the total porosity is reduced; the concrete compactness isenhanced; the concrete compression strength is improved without influencing other performance; meanwhile, the waterproof and anti-seepage effects are obvious; the anti-cracking performance is good; the weather-resistant performance is excellent; the comprehensive performance is high, so that the durability of the concrete structure is improved and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a concrete high-efficiency waterproof and compression-resistant alloy powder and a preparation method thereof. Background technique [0002] Concrete is also called concrete, and concrete refers to the general designation of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. With its wide applicability and price advantages, it has become the largest and most important building structure material in society. my country's concrete has experienced two main development stages of precast concrete and ready-mixed concrete, and has developed into an independent industry from construction engineering. At present, with the continuous improvement of urbanization level and the continuous expansion of national infrastructure construction, the amount of concrete is still increasing year by year, and it will be the m...
