Abstract

The invention discloses a clay-based compound sand consolidating material and belongs to the technical field of sand prevention and consolidation. The clay-based compound sand consolidating material is made of clay, sodium silicate, lewis acid, organic polymer and the like according to a certain ratio. The material is added with water to form solution at certain concentration by adding water, andthe solution is sprayed onto the surface of sand and naturally dries in an open environment to form a consolidated skin; or the clay and sand are uniformly mixed according to a certain ratio and pilled in grids, then solution prepared from the sodium silicate, lewis acid, organic polymer and water is sprayed onto the surface of the grids and naturally dries in an open environment to form consolidated skin, and thus, sand preventing and consolidating clay grids are formed. The consolidated skin of the sand consolidating material disclosed by the invention has high pressure strength, high waterpermeability, high weather resistance, and good sand consolidating effect; and the raw materials are readily available, the sand consolidation process is simple, the cost is low and the clay-based compound sand consolidating material is suitable to be promoted in a large area in desert regions.

Description

Technical field

[0001] The present invention is a sandproof and sand -fixing technology field, which involves a sand fixing material, and especially involves a clay base composite sand fixing material. Background technique

[0002] my country is one of the countries with a very serious desertification. Desertification has seriously affected my country's economic development and social progress. One of the important factors of desertification is the flow of the dunes and occupy a large number of good fields. Therefore The expansion of the existing sand mold area is an urgent task.

[0003] Since the 1950s, Chinese scientific researchers have explored more than 100 desertified governance technologies and prevention models.The methods used are several types of engineering sand, plant sand fixing, and chemical sand.Engineering sand refers to mechanical sand barriers and sand. It mainly uses materials such as firewood, grass, branches, clay, pebbles, plates and other materials. Variou...
