Problems solved by technology

[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, and the adaptability to the soil quality is poor. In addition, the cement production process consumes a lot of energy and mineral resources, which seriously pollutes the surrounding environment.

Embodiment 1

[0014] Carbide slag, granulated blast furnace slag, sodium hydroxide and potassium hydroxide are respectively ground to a Blaine specific surface area of ​​400m 2 / kg, in parts by weight: 89 parts of calcium carbide slag, 10 parts of granulated blast furnace slag, 0.5 part of sodium hydroxide, and 0.5 part of potassium hydroxide are mixed to obtain the soil curing agent of the present invention, which can replace lime as soil reinforcement Material. Wherein the calcium carbide slag can be replaced by quicklime or slaked lime or lime paste or any combination thereof in equal parts by weight, and the granulated blast furnace slag can be replaced by granulated electric furnace phosphorous slag or granulated ferrochrome slag or granulated titanium slag in equal parts by weight Slag or granulated copper slag or granulated nickel slag or any combination thereof instead.

Embodiment 2

[0016] Grind carbide slag, granulated blast furnace slag, fluidized slag, and calcium sulfate separately until the Blaine specific surface area is 400m 2 / kg, in parts by weight: 40 parts of carbide slag, 35 parts of granulated blast furnace slag, 24 parts of boiling slag, and 1 part of calcium sulfate are mixed to obtain the soil curing agent of the present invention, which can replace cement as soil reinforcement material.

Embodiment 3

[0018] Grind calcium carbide slag, granulated blast furnace slag, fly ash and calcium sulfate to a Blaine specific surface area of ​​400m 2 / kg, in parts by weight: 40 parts of calcium carbide slag, 35 parts of granulated blast furnace slag, 24 parts of fly ash, 1 part of calcium sulfate mixed to obtain the soil curing agent of the present invention, which can replace cement as soil reinforcement material .

Abstract

A soil solidifying agent is prepared from calcium carbide dregs (25-90 portions), granualr slags (10-75 portions) of blast furnace and chemical trigger (0.1-5 portions) through grinding, and proportional mixing. Its advantages are broad spectrum, and high effect and durability.

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, and the adaptability to the soil quality is poor. In addition, the cement production process consumes a lot of energy and mineral resources, which seriously pollutes the surrounding environment. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a kind of soil solidifying agent which has strong adaptability to various soils, good soil-fixing effect, good durability of solidified soil, and can utilize industrial waste. [0004] The soil solidifyi...
