Iron tailing sand concrete and preparation method thereof

Abstract

The invention relates to the field of building concrete, and particularly relates to iron tailing sand concrete and a preparation method thereof. The concrete is prepared from the following raw materials in parts by weight: 20 to 40 parts of tailing ball, 10 to 20 parts of tailing powder, 5 to 15 parts of cement and 2 to 6 parts of water, wherein the tailing ball is prepared from the following rawmaterials in parts by weight: 8 to 12 parts of cement, 36 to 48 parts of tailing powder, 17.6 to 24 parts of water, 1.6 to 2.4 parts of water reducing agent and 0.24 to 0.36 part of rubber powder. The preparation method comprises the steps of preparation of the tailing ball and preparation of the concrete. The iron tailing sand concrete and the preparation method thereof are provided; the concrete is high in strength and meets the requirement of concrete for a building; meanwhile, the concrete utilizes the iron tailing sand as the raw material; the waste is utilized anew; the pollution of tailing to an environment is reduced; the preparation method is simple; the obtained concrete is high in strength; the tailing ball is used as an aggregate; further, the strength of the obtained concreteis higher than the strength of the aggregate; the concrete is researched from a microscopic angle, and the practicability is high.

Description

technical field [0001] The invention relates to the field of building concrete, in particular to an iron tailings sand concrete and a preparation method thereof. Background technique [0002] Iron tailings are the waste after mineral processing and are the main component of industrial solid waste. The impact of iron tailings on the environment is very large. After years of rapid GDP development in China, due to the extensive development, it has brought a series of problems: tailings are piled up everywhere, which is easy to cause dam failure and threaten the lives of local residents; Tailings are piled up all over the place, which is easy to be brought into rivers by floods, which can silt up rivers and cause water pollution; tailings are piled up everywhere, which is easy to cause strong wind and dust, pollute air, cause soil pollution, pollute crops, cadmium rice incident, etc. Therefore, iron The tailings are very polluting to the environment, and the amount of iron tail...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of existing iron tailings pollution such as large pollution, difficult treatment and high concrete cost, and provide a kind of iron tailings sand concrete and its preparation method. The concrete has high strength and meets the requirements of building concrete, and at the same time The concrete uses iron tailings sand as a raw material, reutilizes the waste, and reduces the pollution of the tailings to the environment. Material strength, and research on concrete from a microscopic point of view, strong practicability
