Problems solved by technology

The stacking of red mud will occupy a large amount of land resources, causing waste of resources and problems of the natural environment
Because the chemical alkali combined with red mud is difficult to remove and has a large content, and contains fluorine, aluminum and other impurities, it has been difficult to use red mud harmlessly.

Abstract

The invention discloses red mud-based foam light soil as well as a preparation method and application thereof. The red mud-based foam light soil is prepared from the following preparation components in parts by mass: 300 to 360 parts of red mud, 40 to 80 parts of cement, 90 to 140 parts of an excitant, 10 to 30 parts of foam and 250 to 350 parts of water, wherein the excitant is selected from at least one of gypsum, quick lime, alkali metal silicate, alkali metal sulfate, alkali metal carbonate, alkali metal hydroxide, alkyl sulfonic acid alkali metal salt, alkyl benzene sulfonic acid alkali metal salt and alkyl sulfuric acid alkali metal salt. By adopting the red mud-based foam light soil provided by the invention, natural resources can be saved, the pollution of red mud to the environment can be reduced,the preparation cost can be reduced, and the problem of treatment of solid waste materials can be solved. The method for preparing the red mud-based foam light soil is simple in process and high in production efficiency and safety, the quality meets the construction requirement when the method is applied to road construction, resources can be comprehensively utilized, and the method has good market prospects and application value.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a red mud-based foam lightweight soil and its preparation method and application. Background technique [0002] With the rapid advancement of economic construction and urban reconstruction and expansion, road engineering construction plays an increasingly important role in economic development. As a new type of lightweight roadbed filler, foam light soil is formed by foaming the foaming agent aqueous solution through a foaming device, and mechanically stirring with cement-based cementitious materials, aggregates, admixtures and water. Lightweight composite material has the advantages of light weight, good fluidity, stable performance, strong uprightness, high strength and low impact on the environment. It has been widely used in civil engineering construction fields such as roads, underground engineering, and municipal buildings. [0003] At present, the vast majority...
