Abstract

The invention relates to a curing agent of concrete, comprising styrene-acrylic emulsion, acrylamide solution, sodium silicate solution and organosilane solution; the styrene-acrylic emulsion is poured into the acrylamide solution; the sodium silicate solution and the organosilane solution are added and uniformly stirred with low speed to form the curing agent of the concrete; water soluble material with good film forming ability is used without solvent; neither volatile substances are generated nor secondary environmental pollution are caused; the invention comprises organosilane, rapidly penetrates into capillary pores wall inside the concrete, and then chemically reacts with part of the water and air in the concrete to generate silicon dioxide; the capillary pore channels are blocked, and a solid waterproof layer is formed to prevent evaporation of internal moisture and avoid invasion of external harmful substance, which helps to improve the durability of the concrete, keeps the concrete in a maintenance state for a long period, and improves durability of the concrete.

Description

technical field

[0001] The invention relates to a water-based building material, in particular to a concrete curing agent. Background technique

[0002] After the cement concrete is poured, it is necessary to have the necessary temperature and humidity during the initial setting process to ensure sufficient moisture for the hydration reaction to proceed completely. The traditional maintenance methods include laying grass bags, plastic films and watering. These methods are time-consuming , laborious, can not effectively block the evaporation of water, low water retention rate, poor maintenance effect.

[0003] In order to improve its water retention rate, various concrete curing agents have appeared at present. The commonly used concrete curing agents are divided into two types: inorganic and organic. The inorganic type is mostly silicate concrete curing agents. The performance is low, and it cannot effectively prevent the efflorescence of concrete pores. After spraying and ...
