Problems solved by technology

The former is cheap, but has poor cohesive force, poor deformation ability, easy to shrink and crack, and easy to leak
The latter has the advantages of good adhesion, no shrinkage and good deformation ability, but also has the disadvantages of long-term heat resistance, the storage stability of one-component adhesives is greatly affected by packaging and the outside world, and bubbles and cracks may occur when curing in a high-humidity environment. Disadvantages, especially the high cost limit its large number of applications
The shaped sealing materials used in building se

Abstract

The invention relates to an assembled splicing joint sealing material for building components and an application thereof. The sealing material is prepared from raw materials in parts by weight as follows: 100 parts of cement, 0-150 parts of active admixture, 0.01-10 parts of water reducer, 0.01-10 parts of early strength agent, 0-10 parts of thickening time control agent, 0.1-30 parts of expanding agent, 0-30 parts of bonder, 0.01-30 parts of plastic retaining agent, 0.01-10 parts of starch ether, 0-10 parts of thixotropic lubricant and 0-300 parts of quarts sand. The sealing material can be applied to sealing joint of concrete components spliced. Compared with the prior art, the sealing material is good in construction performance, and can be used by adding water to stir. The sealing material can be quickly constructed by a caulking gun or an electric caulking device, and the operating time is long. Newly mixed slurry has good plasticity, adhesive force and resistance to falling. The sagging phenomenon is further avoided when a vertical direction is spliced. The condensing time is adjusted according to the project demand, the early strength is high and the later strength is continuously increased.

Description

technical field [0001] The invention belongs to the technical field of building materials and building construction, and in particular relates to a seam sealing material for assembled building components and its application. Background technique [0002] The prefabricated concrete structure is referred to as PC (Prefabricated Concrete). Its technology is to form a concrete structure with prefabricated concrete components as the main component, which is assembled, connected, and partially cast in place. PC housing has many advantages such as high efficiency and energy saving, green environmental protection, cost reduction, and providing housing functions and performances. It will also become the main form of architectural design and construction in the near future. In today's international construction field, the application form of PC projects varies from country to country and from region to region, and is still in the development and research stage in mainland China. The ...
