Problems solved by technology

The advantage of this vegetative concrete alkaline inhibitor is that it can reduce the alkalinity of the concrete surface within a certain range. The disadvantage is that the specific components react with the cement particles inside the concrete, which affects the bonding between cement and stones. Ultimately, it will affect the strength and durability of planting concrete, etc.

Abstract

The invention discloses a vegetation concrete surface sealant and a method for performing surface treatment on vegetation concrete. The vegetation concrete surface sealant is prepared from the following ingredients in percentage by mass: 50 to 60 percent of polyacrylic emulsion, 3 to 5 percent of thickening agents and the balance of water, wherein the viscosity of the sealant is 25 to 30s; after the sealant is uniformly sprayed to the surface of the vegetation concrete for a period of time, the alkaline value and the compressive strength of the surface are tested; through comparison with the values before spraying treatment, the research finds that the sealant can effectively reduce the surface alkalinity of the vegetation concrete; the performance such as the compressive strength of the vegetation concrete is not influenced; as a slope protection material, the vegetation concrete surface sealant has good application prospects in the field of building materials.

Description

technical field [0001] The invention relates to a concrete surface sealing agent, which belongs to the technical field of building materials, in particular to a vegetation concrete surface sealing agent and a method for surface treating the vegetation concrete. Background technique [0002] Porous vegetation concrete is a new type of slope protection material that can adapt to the growth of plants and has the function of slope protection. Compared with ordinary concrete, it has the same high strength and durability. It has increased by 2 to 3 times, so the research on porous vegetation concrete has very important significance. [0003] However, in my country, ordinary Portland cement is usually used to produce porous concrete, and ordinary Portland cement is prone to produce soluble and insoluble alkalis during the cementation process. Among them, soluble alkalis such as sodium carbonate and sodium bicarbonate can make The amine nitrogen fertilizer decomposes and escapes, ca...
