Abstract

The invention belongs to the technical field of engineering materials and discloses an assembling type building sleeve grouting material. The assembling type building sleeve grouting material is prepared from the following raw materials in parts by weight: 30-40 parts of cement, 3-8 parts of ultrafine steel slag powder, 2-6 parts of phosphorus gypsum, 3-5 parts of ceramic microbead, 30-50 parts ofquartz sand, 20-30 parts of broken nickle slag sand, 0.05-0.5 part of retarding and water-reducing agent, 0.05-0.1 part of reinforcing agent, 0.5-2 parts of shrinkage-reducing expanding component, 0.001-0.005 part of defoaming agent and 0.005-0.01 part of xanthan gum. The assembling type building sleeve grouting material disclosed by the invention has better fluidity and strong groutability, canpermeate into fine cracks or gaps, causes no water exudation and separation and can meet the requirements of the assembling type building.

Description

technical field [0001] The invention belongs to the technical field of engineering materials, and in particular relates to an assembled building sleeve grouting material. Background technique [0002] The prefabricated building is a kind of prefabricated construction of building materials in the factory. After the construction unit has processed the terrain, it uses a light steel structure to combine various light materials. The building method that integrates functions such as moisture-proof and moisture-proof is also called industrialized building. Because of its advantages such as stable construction quality, convenient and quick construction, and labor saving, it has been vigorously promoted in recent years. In prefabricated buildings, the connection methods mainly include sleeve grouting connection, grout anchor connection and indirect connection, among which the sleeve grouting connection is the main one, with a market share of 80%. As an important connection medium ...
