Problems solved by technology

[0004] The technical problem to be solved by the present invention is to propose a high-performance prefabricated building steel sleeve grouting material, which is replaced by mountain sand or river sand, in view of the situation that the price of the grouting material that meets the standard is high and the quality of the grouting material with a low price cannot meet the standard. Quartz sand is used as aggregate, which greatly reduces the production cost while ensuring the strength of the grouting material

Abstract

The invention discloses a high-performance assembling type construction reinforcing steel bar sleeve grouting material and a using method thereof, and belongs to the technical field of building materials. The grouting material consists of the following components in parts by mass: 80 to 100 parts of cement, 0 to 80 parts of quartz sand, 10 to 100 parts of mountain sand or river sand, 5 to 15 partsof an expanding agent, 0 to 1 part of a set retarder, 0.5 to 3 parts of a water reducing agent, 0 to 1 part of a defoaming agent and 15 to 80 parts of steel slag powder. When the grouting material isused, the cement, the quartz sand and steel slag are uniformly mixed in proportion first, then 2 to 3 times of water is added slowly, the materials are stirred, the expanding agent, the set retarder,the water reducing agent and the defoaming agent are added in proportion in a stirring process, and after the materials are stirred uniformly into the grouting material, the grouting material can beused. According to the grouting material, the quartz sand is partially or completely replaced by adopting the river sand or the mountain sand, the using of complex admixtures is reduced, and industrial waste steel slag is added, so that the performance of the grouting material can be maintained, and meanwhile, the cost is greatly reduced; therefore, the grouting material is suitable to be widely applied in an assembling type construction reinforcing steel bar sleeve grouting material.

Description

technical field [0001] The invention relates to a high-performance assembled building reinforcement sleeve grouting material, which belongs to the technical field of building materials. Background technique [0002] At present, with the increasing promotion of prefabricated buildings in the country, more and more grouting materials are used. Most of the existing grouting materials are mainly composed of cement, quartz sand, expansion agent, retarder, and water reducing agent. , the compressive strength of this kind of grouting material is ≥85MPa, which can meet the basic performance of the grouting material specification, but the main indicators such as vertical expansion rate and fluidity cannot meet the standard requirements, especially the fluidity, and most domestic grouting materials cannot meet the standard requirements , After 10 minutes, the solidified state appeared. In order to meet the standard strength standard, the existing technology usually uses quartz sand a...
