Abstract

The invention discloses a concrete air-entraining and water-proof agent and belongs to the field of building materials. The concrete air-entraining and water-proof agent comprises the following components in parts by weight: 40-60 parts of rosin, 6-20 parts of sodium alginate, 5-12 parts of sodium hydroxide, 3-10 parts of sodium dodecyl benzene sulfonate, 15-40 parts of stearic acid and 0.5-3 parts of sulfuric acid. Tiny bubbles can be uniformly introduced to the concrete air-entraining and water-proof agent, the workability and the water-proofness are improved, the concrete durability is enhanced; and the concrete air-entraining and water-proof agent has excellent air-entraining performance and bubble stability performance and is suitable for concrete structures with anti-freezing and water proof demands.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a concrete air-entraining waterproofing agent. Background technique [0002] The booming construction industry has led to a continuous increase in the demand for construction materials. In order to improve the performance of concrete, the main material of construction, various concrete additives emerge in endlessly. Among them, there are many concrete air-entraining agents to improve the durability and frost resistance of concrete. However, existing concrete air-entraining agents have complex formulas, uneven bubble induction, poor waterproofing and other deficiencies. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a concrete air-entraining waterproofing agent. [0004] The technical scheme adopted in the present invention is a concrete air-entraining waterproofing agent, comprising rosin,...
