Abstract

The invention discloses an easy-to-shape cement-based crack sealer for installation of prefabricated members, and a construction method thereof. The cement-based crack sealer comprises, by weight, 30-50 parts of quick-setting cement, 25-40 parts of river sands, 10-20 parts of fine ceramic powder, 3-6 parts of a shaping compound, 5-15 parts of rubber powder, 1-5 parts of a coagulant, and 0.3-0.8 part of chemical chopped fibers. The crack sealer developed by using a quick-setting cement system and preferably choosing composite aggregates and the shaping control compound meets the construction requirements of the special construction technology of the prefabricated members for the excellent shaping performance of the material, also has the advantages of fast construction speed, good anti-disturbance performance and excellent sealing performance, and significantly improves the construction efficiency and the overall quality of the installation of prefabricated members.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an easy-to-shape cement-based joint sealing material for assembly-type component installation and a construction method thereof. Background technique [0002] Before the sleeve grouting of prefabricated components, cement-based materials should be used to seal the inner or outer edges of the joints of the components. It is generally divided into two types: the seat slurry method and the slotted warehouse method: after laying the seat slurry on the base, the construction method of hoisting wall panels, doors and other components to the seat slurry and then compacting it is the seat slurry construction method; After the components are hoisted and fixed, the outer edge is blocked and sealed, and then the method of grouting inside is called the closed warehouse construction method. [0003] The joint sealing material is a sealing material used to seal the outer gaps of ...
