Problems solved by technology

This kind of soil solidification technology has the following disadvantages in the actual implementation: 1) the mechanical strength is limited, and it is difficult to achieve the mechanical strength required for road construction due to the need to mix with soil in different places; 2) the stability is poor, after the cementation is completed That is, to achieve the best mechanical strength, the strength cannot grow steadily in the later stage, the gel structure cannot be recovered after being damaged by external force, and the mechanical strength of the overall structure is unsustainable; 3) The frost resistance is poor. The cementitious structure after construction cannot meet the engineering mechanical indicators required for road construction

Abstract

The invention discloses a high-strength soil-fixing rock powdery material, a preparation method and application thereof. The components of the raw materials are blended through a specific material preparation method, the soil fixation rock material with different raw material ratios is prepared according to different soil texture types and different characteristics, the soil fixation rock material is self-hardened and coagulated at normal temperature and normal pressure and is subjected to isomorphic reaction with soil particle minerals on an interface, a space network staggered structure is formed in the solidified body, so that the material has high strength, high water stability and anti-permeability and anti-freezing performance. Through application of the high-strength soil fixation rock powdery material, tracking observation is carried out on the strength of a road section, and it is observed that the appearance of the road surface of the road section is smooth and free of subsidence, ruts, longitudinal and transverse cracks and reflection cracks.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-strength soil-fixing rock powder material, a preparation method and an application. Background technique [0002] In ancient China, in order to meet people's basic production and living needs, local materials were used, and grass tendon, ginger stone and glutinous rice mortar were used to improve the engineering properties of the soil. With the progress of society, the invention and development of cement and lime, cement and lime were first used to improve and solidify the soil. With the rapid development of China's economy, infrastructure construction has entered a period of investment climax, and the cement and lime industry has developed rapidly. At the same time, it has brought difficulties Serious problems that have been neglected; massive consumption of energy and resources, cutting mountains and rocks, and excessive mining of river sand have caused soil erosion and...
