AI Technical Summary

Problems solved by technology

Does not protect against corrosion because it does not change the chemical structure of the concrete
Furthermore, because the content of free calcium in concrete is very small, especially on the old ground, the alkaline concrete sealant and curing agent basically cannot meet the hardness requirements, and after the insufficient hardness is destroyed, the crystallized silicate absorbs water again Dissolves

Abstract

The invention relates to a concrete surface sealing curing treatment enhancing agent comprising the components of, by mass: 3-8% of a penetrating agent, 20-45% of an accelerator, 3-5% of a complexing agent, 2-5% of a dispersing agent, 4-8% of a nano-grade active agent, and 35-60% of water. The penetrating agent is a mixture of fatty alcohol polyoxyethylene ether phosphate and alkyl phosphate with a mass ratio of (0.5-1.5):1. The accelerator is a mixture of lithium silicate, lithium carbonate and sodium nitrite with a mass ratio of (0.5-1):(0.1-1):(2-5). The complexing agent is a mixture of triethanolamine and diethanol monoisopropanolamine with a mass ratio of 1:(0.5-2). The dispersing agent is a melamine water reducing agent. The nano-grade active agent is nano-grade calcium carbonate. The concrete surface sealing curing treatment enhancing agent has low alkali content. When the enhancing agent is used in concrete surface treatment, the concrete surface layer can be denser; the structure can be more compact; and concrete durability is improved.

Description

Technical field [0001] The invention relates to a curing treatment agent for concrete surface, in particular to a concrete surface sealing curing treatment strengthening agent. Background technique [0002] At present, China usually mixes fly ash and / or mineral powder into cement or concrete with ordinary marks. When fly ash and / or mineral powder are added to cement or concrete, due to construction vibrating, the concrete slurry floats up, the surface water-binder ratio of concrete is high, and the content of fly ash and / or mineral powder is relatively high. This not only affects the surface strength and chromatic aberration of the concrete, but also has a greater impact on the weathering resistance of the concrete surface and the surface pulverization and sanding, which in turn affects the actual service life of the concrete. The concrete surface sealing and curing treatment enhancer is an advanced concrete caulking agent, hardener and compacting agent, which can penetrate into...
