Concrete reinforced curing agent

Abstract

The invention discloses a concrete reinforced curing agent. The concrete reinforced curing agent comprises, by mass, 80 to 100 parts of a silicone-acrylic emulsion, 5 to 10 parts of sodium silicate, 1 to 10 parts of aluminum sulfate, 1 to 5 parts of an early strength agent, 1 to 5 parts of a hydrophobic agent, 0.1 to 2 parts of a leveling agent, 1 to 5 parts of refined konjac flour and 1 to 10 parts of deionized water. The silicone-acrylic emulsion comprises active silicone resin, styrene, isooctyl acrylate, acrylamide, a silane coupling agent, sodium persulfate, methyl methacrylate, 2, 2, 4-trimethyl-1, 3-pentanediolmono(2-methylpropanoate) and deionized water according to a mass ratio of 20: 13: 22: 0.2: 0.1: 4: 2: 3: 30. The inorganic curing agent and the organic curing agent are compounded to form a protection film on the concrete surface and penetrates into the concrete to react with the concrete material so that the evaporation of water is prevented, the concrete forms a compact structure, the strength and crack resistance of the concrete are improved, volume shrinkage is reduced and high water retention property and weather resistance are obtained.

Description

technical field [0001] The invention relates to the technical field of concrete curing, in particular to a reinforced concrete curing agent. Background technique [0002] Concrete curing agent, also known as concrete surface water-retaining agent, is a concrete admixture that can effectively prevent internal moisture from evaporating when sprayed on the surface of newly poured concrete or mortar. Concrete curing agents mainly include water glass type, paraffin emulsion type, polymer emulsion type, inorganic-organic composite type, water-absorbing resin type and other types of curing agents. At present, curing agents on the market generally have defects such as low water retention rate, poor stability, and poor durability, while water glass type curing agents also have defects such as low water retention rate and large application amount, and paraffin emulsion type curing agents are more sensitive to high temperature environments. , the cost of polymer emulsion is high, and ...
