Pervious concrete water-based covering protective agent

Abstract

The invention discloses a pervious concrete water-based covering protective agent. The pervious concrete water-based covering protective agent is prepared from the following components in parts by mass: 800 to 1100 parts of cementing material, 0.2 to 3 parts of functional admixture, 0.01 to 0.1 part of material adhesive admixture, 0.1 to 1.5 part of thickening agent and 50 to 150 parts of deionized water. According to the pervious concrete water-based covering protective material disclosed by the invention, an inorganic active material and an organic bonding material are organically combined by a double charge protection and coupling scheme; organic resin is modified by the inorganic material, and the surface of the inorganic material is protected by using double charge through the functional admixture, so that the stability of the inorganic material in an organic system is improved, and thereby the strength and friction resistance of a system are improved.

Description

technical field [0001] The invention relates to the technical field of permeable concrete overlay protection agent in engineering material technology. The material is mainly used for permeable concrete surface overlay protection, and can also be used as other building structure surface protection materials. Background technique [0002] Cement concrete is a porous material. In addition to the macropores visible to the naked eye, there are also a large number of capillary pores. These micropores are very easy to absorb water through capillary action, and harmful chemicals such as chloride ions and sulfates will also enter with water. Inside the cement concrete, it will cause various erosion and damage of concrete and steel bars, reducing the service life of concrete. [0003] At present, the protection of concrete has not received the attention of relevant departments. Only relevant specifications such as marine concrete used in corrosive environments and fair-faced concrete ...

Problems solved by technology

The coating endows Portland concrete curbs with decorative and protective functions, weather resistance, and temperature change resistance, but its composition is too complicated, the ingredients are difficult, the preparation method is too cumbersome, and the cost is high; it is not conducive to mass production and on-site Modulation, the construction process is complicated, and the coating penetration depth is insufficient, and the protective effect is poor; and the weather resistance and durability of this water-based fluorocarbon coating are not obvious, and the coating penetration depth is insufficient

The combination with the foundation is poor, the protective effect is poor, and there is a certain degree of environmental pollution
