Abstract

The invention provides a soil curing agent doped with sludge incineration ash. The soil curing agent is prepared from the following materials in parts by weight: 0-30% of sludge incineration ash, 5-10% of gypsum, 40-55% of slag powder and 20-30% of cement; when the curing agent is used for reinforcing a high-soft soil foundation, the dosage ratio of the curing agent to soft soil is 10%-30%; when the curing agent is used for roadbed reinforcement, the dosage ratio of the curing agent to soil is 4-15%. According to the soil curing agent doped with the sludge incineration ash, multiple solid wastes are synergistically matched, chlorine salt and sulfate components in the sludge incineration ash serve as exciting agents, strength is provided for the soil body, the curing agent is an environment-friendly curing agent integrating multiple solid wastes, and on the premise that the same curing effect as cement is achieved, the cost is lower than cement; besides, development of the soil curing agent finds a way for disposal and utilization of sludge incineration ash, and meanwhile, various solid wastes can be consumed, so that resource and energy conservation and waste utilization and new material development are realized.

Description

technical field

[0001] The invention relates to the technical field of curing agents, in particular to a soil curing agent mixed with sludge incineration ash and a preparation method thereof. Background technique

[0002] Stirring pile technology (wet method, dry method) is a common method for strengthening soft ground before foundation pit excavation in underground engineering. Usually, deep mixing method, high-pressure jet grouting method and other construction techniques are used to spray curing agent to make curing agent and soft soil The soil reacts to form a temporary mixing pile retaining wall with high strength. At present, cement is the main curing agent for mixing piles used in most projects. Due to its high strength and stable performance, cement has become one of the most important soft soil foundation treatment technologies in my country. However, the cement production process requires high-temperature calcination and releases a large amount of carbon dioxide. ...
