The invention relates to a curing agent, and discloses a novel environment-friendly composite curing agent and its application. The invention belongs to the field of building materials; it consists of the following ingredients in parts by weight: 30-45 parts of binder, 10 parts of water-removing agent ~17 parts, reinforcing agent 15~20 parts, filler 10~20 parts, catalyst 2~5 parts; The formula of the present invention is reasonable, is widely used in pile foundation, ground connecting wall and shield etc. construction waste mud and river course silt Green disposal project; the new environmentally friendly composite curing agent is composed of organic and inorganic substances, and the main component is organic materials; Good effect and other advantages.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an application method of an environment-friendly composite curing agent. Background technique [0002] With the rapid development of my country's economy, environmental protection and sustainable development are becoming more and more important. Therefore, green construction technology in the construction industry is more and more widely used, but there are still some problems in the green treatment of construction waste mud and river sludge, such as solidification The addition of a large amount of curing agent will cause secondary pollution to the environment, or the reaction of the existing curing agent is slow, etc.; the current curing of mud is mostly treated with inorganic cementitious materials, but the reaction time of inorganic curing agent is long, the state is unstable, and it is easy to pollute the environment. Many; these restrict the efficient and green development of...
