High proportion red mud building material

Abstract

High-ratio red mud building materials, including red mud, chromium slag, light-burned magnesium powder, magnesium chloride brine, water reducer; fly ash and modifiers; mix red mud raw materials and chromium slag evenly, Mix with red mud and chromium slag premix evenly and add to magnesium chloride brine, stir for 2 to 5 minutes, add modifier, continue stirring for 3 minutes, then add water reducer; add water to red mud and chromium slag composite raw material powder, After fully stirring, the red mud magnesia gel composite material slurry is obtained, the red mud magnesia gel composite material slurry is poured into a mold, and the high-mixing ratio red mud building material is obtained by demoulding. Under the condition of high blending ratio of red mud, it has excellent flexural strength, compressive strength and softening coefficient, and is suitable for most construction environments. There are no problems such as halogen return and blooming, and it meets the requirements of many fields in roads, bridges, houses and many other aspects. In this way, the red mud and chromium slag can be comprehensively utilized, and the environmental pollution caused by red mud and chromium slag stacking can be reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building material with a high mixing ratio of red mud. Background technique [0002] The comprehensive treatment and utilization of red mud is a worldwide problem. In recent years, with the strengthening of environmental protection, the discharge of red mud has been greatly improved, but this cannot fundamentally change the pollution of red mud to the environment. Only by realizing the resource utilization of red mud can we fundamentally solve the problem. [0003] For this reason, domestic and foreign scholars have done a lot of research work on the comprehensive treatment of red mud, and have also made many significant progress. However, the existing red mud recycling methods have the disadvantages of low red mud content, low red mud utilization rate, high energy consumption, etc., and cannot consume a large amount of red mud. For example, the existing red mud i...
