Soil firming agent

Abstract

A soil curing agent, which includes calcium carbide slag, granulated blast furnace slag, and a chemical activator, and the carbide slag, granulated blast furnace slag, and chemical activator are respectively ground to a Blaine specific surface area of ​​300-900m 2 / kg, in parts by weight: 25-90 parts of calcium carbide slag, 10-75 parts of granulated blast furnace slag, and 0.1-5 parts of chemical activator. Due to the use of a large amount of industrial waste, it not only saves raw materials, but also protects the natural environment. Carbide slag and chemical activators can effectively destroy the glass body in granulated blast furnace slag and form low-alkaline calcium silicate hydrate. Glue, the microstructure of the formed solidified soil is uniform. The purpose of the invention is to provide a soil solidifying agent which has strong adaptability to various soils, good soil-fixing effect, good durability of the solidified soil, and can utilize industrial waste.

Description

technical field [0001] The invention relates to a soil curing agent in the field of building materials. Background technique [0002] Traditional soil reinforcement materials are mainly lime and cement. Lime can be used for shallow roadbeds or house foundations, but not for soft soil layers with high water content; although cement can be used to reinforce soft soil layers, cement is used to strengthen soil The soil effect is not good, the adaptability to soil quality is poor, and its cost is also very high. In addition, the production of cement consumes a lot of energy and mineral resources, which seriously pollutes the surrounding environment. On March 8, 2000, the State Intellectual Property Office published an application for an invention patent with the application number 98112230.2 and the title of the invention "the formula and preparation method of the new gypsum slag cement for the filling of Chinese waste slag". It is a kind of industrial waste, but its components...

Lime can be used for shallow roadbeds or house foundations, but not for soft soil layers with high water content; although cement can be used to reinforce soft soil layers, cement is used to strengthen soil The soil effect is not good, the adaptability to the soil quality is poor, and the cost is also very high

In addition, cement consumes a lot of energy and mineral resources in the process of production, which seriously pollutes the surrounding environment

On March 8, 2000, the State Intellectual Property Office published an application for an invention patent with the application number 98112230.2 and the title of the invention "the formula and preparation method of the new gypsum slag cement for the filling of Chinese waste slag". It is a kind of industrial waste, but its components do not include carbide slag waste, and the carbide slag waste produced during the production of acetylene is difficult to deal with. A large amount of carbide slag waste will pollute the environment, and the consequences are quite serious
