Highly-controllable strength and dimensionally-stable curing material

Abstract

The invention relates to a method of preparing the solidifying material which has high performance in controlling intensity and stabilizing size, and a process of using the material to solidify granular materials such as common soil mass, weathered gravel, standard sand stone, industrial solid waste, tailing sand and sea sand to form indurations. The process comprises the following steps: (1) preparation of core materials; (2) preparation of the solidifying material which has high performance in controlling intensity and stabilizing size; (3) process of producing the solidifying material which has high performance in controlling intensity and stabilizing size; (4) application that the solidifying material which has high performance in controlling intensity and stabilizing size can be used to solidify granular materials such as common soil mass, weathered gravel, standard sand stone, industrial solid waste, tailing sand and sea sand in road projects, foundation engineering as well as water conservancy and hydropower projects, compared with traditional solidifying method, the process has the advantages that the intensity is controllable, the size is stable, the water resistance is dramatic and the construction is convenient with the general use amount ranging from 4% to 12%. As to the construction method, the construction technical process or specifications of soil lime and concrete can be referred to.

Description

technical field [0001] The invention relates to a preparation method of a high-performance controllable strength and dimensionally stable solidification material, and a method for solidifying bulk materials such as general soil, weathered gravel, standard gravel, industrial solid waste, tailings sand, and sea sand by using the material. The process of forming a consolidated body. The invention belongs to the technical field of material science. Background technique [0002] The consolidation of general soil, weathered gravel and other bulk materials under normal temperature and pressure is a commonly used foundation soil improvement method in road engineering, civil engineering, hydropower engineering and other engineering constructions to improve the bearing capacity and stability of the foundation. Big and versatile. The cementing material usually used for the consolidation of soil under normal temperature and pressure is inorganic materials such as lime or cement. The a...

AI Technical Summary

Problems solved by technology

Conventional inorganic cementitious materials such as lime and cement are used as the foundation to consolidate the soil. The biggest problem is poor dimensional stability and resistance to water erosion; , in addition to factors such as construction, overrunning and overloading, almost 90% are directly related to road foundation instability and damage

[0003] Maintaining the advantages of lime soil, cement soil, etc., overcoming the disadvantages of poor dimensional stability and resistance to water erosion, and developing high-performance, controllable strength and dimensionally stable consolidated materials have engineering practical significance
