Abstract

The invention relates to the technical field of bin sealing seat slurry, in particular to bin sealing seat slurry matched with PC building component installation and a preparation method of the bin sealing seat slurry, and the bin sealing seat slurry comprises the following components: Portland cement, quartz sand, redispersible latex powder, active powder and other additives, wherein the proportions of the components are as follows: 35% of Portland cement; 45% of quartz sand; 8% of redispersible latex powder; 6% of active powder; other additives: 2%. The bin sealing seat slurry has excellentthixotropy and good plastic operability, and does not droop, slip or collapse; the early strength is high, and the middle strength and the post strength are continuously and stably increased; after the slurry is cured, the shrinkage rate is low, the texture is compact and hard, and the anti-permeability and anti-deformation capabilities are strong; the product is smooth in construction operability, fresh in slurry and easy to operate, and can be operated for about 1 hour.

Description

technical field [0001] The present invention relates to the technical field of sealing seat slurry, and specifically relates to a sealing seat slurry for PC building component installation and a preparation method thereof. Background technique [0002] PC prefabricated building components are equipped with a matching sealer slurry, which is used to weld the 2-4cm wide gap at the bottom of the component. According to the requirements of the component characteristics, it has high early strength, high strength, extremely low shrinkage and Excellent caulking performance. In the early stage and at present, some of these construction projects still use non-specific and non-supporting ordinary mortar for construction, and there are some shortcomings such as cracking, poor waterproofing, low strength, and difficult operation and construction. In view of this, we propose a kind of PC building component installation matching sealant slurry and its preparation method. Contents of th...
