Abstract

The invention discloses a concrete adhesive. The concrete adhesive comprises the following materials in parts by weight: 50-80 parts of epoxy resin, 10-20 parts of acetone, 5-8 parts of ethylenediamine, 10-20 parts of dibutyl phthalate, 50-80 parts of quartz sand, 40-60 parts of cement, 20-40 parts of imide and 100-200 parts of water. Compared with the prior art, the adhering strength of the concrete adhesive disclosed by the invention is 2-3Mpa, the curing water temperature is 10-20 DEG C after underwater construction and the curing time is 7days; and the concrete adhesive has the advantages that adhering strength is high, construction is convenient, curing time is short and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and more specifically relates to a concrete adhesive. Background technique [0002] After the concrete has been used for a long time, it is prone to cracking due to the volatilization of moisture contained in it. The current way is to often sprinkle water on the concrete surface for maintenance or repair. But these methods are all cumbersome, and the operation is not very convenient. Adhesives can be added to concrete to enhance the adhesion between concrete, which can effectively prevent concrete cracking. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a concrete adhesive. [0004] To achieve the above object, the present invention has taken the following technical solutions: [0005] A concrete adhesive, in parts by weight, consists of the following substances: [0006] Epoxy resin: 50~80, ac...
