Abstract

The invention belongs to the field of prefabricated part building materials, and particularly relates to a sleeve grouting material for a prefabricated part and a preparation method of the material. The grouting material is formed by mixing sleeve grouting material dry powder for prefabricated parts with water and a polycarboxylate superplasticizer. The grouting material dry powder is prepared from the following components in parts by weight: 70 to 100 parts of cement, 75 to 100 parts of mixed sand, 20 to 30 parts of glass powder, 1 to 3 parts of expanding agent, 1 to 3 parts of thickening agent and 1 to 3 parts of toughening agent; the mass ratio of the sleeve grouting material dry powder for the prefabricated part to water is 1:(0.1-0.15); and the polycarboxylate superplasticizer is a comprehensive shrinkage-reducing polycarboxylate superplasticizer, the mixing amount of the polycarboxylate superplasticizer is 2%-3%, and the polycarboxylate superplasticizer has the effects of defoaming and low hydration heat. According to the introduced comprehensive shrinkage-reducing type polycarboxylate superplasticizer, the influence of bubbles of the polycarboxylate superplasticizer in the using process can be effectively reduced, the hydration heat of cement can be reduced, shrinkage of the sleeve grouting material in the using process of a prefabricated part is reduced, and large-scale application and popularization of the prefabricated part are facilitated.

Description

technical field [0001] The invention relates to the field of prefabricated component building materials, in particular to a sleeve grouting material for prefabricated components and a preparation method thereof. Background technique [0002] As the concept of green environmental protection is becoming more and more popular, for the construction industry, the application of green building materials and green buildings is becoming more and more extensive. As the main means of building green development, the steel sleeve grouting connection technology is involved in various fields such as industrial and civil construction, road bridges, underground engineering, ocean engineering, and nuclear power engineering. The grouting connection technology adopts the method of factory prefabricated components and on-site connection, which not only reduces the cumbersome construction procedures, but also saves energy, reduces emissions, and protects the environment. Factory prefabrication ...
