Problems solved by technology

[0003] At present, the main properties of domestic polymer cement waterproof coatings are manifested in tensile strength, elongation at break, low temperature flexibility (-10°C), bonding strength, water impermeability, impermeability, etc., and its low temperature flexibility is far below that of Requirements for going to alpine regions (-40°C)
In addition, the overall performance of the protective coating is related to the actual construction environment, especially for water bubbles, freeze-thaw, low temperature, ultraviolet rays, and the weak bond between the powdered concrete layer and the protective layer. The current polymer cement waterproof coating cannot meet the high and cold conditions. Pulverization treatment of regional concrete

Abstract

The invention discloses a protective coating for concrete powdering and remediation and a construction method thereof. The protective coating consists of a permeating waterproof material layer, quickrepair mortar, a functional interface agent layer and a cement-based high-elastic flexible waterproof material layer. The protective coating is sequentially provided with the permeating waterproof material layer, the quick repair mortar, the functional interface agent layer and the cement-based high-elastic flexible waterproof material layer from inside to outside. The construction method includesthe following steps that situation investigation is carried out, base surface is cleaned, permeating waterproof material is coated, the quick repair mortar is used for base surface repair, the functional interface agent is coated, and cement-based high-elastic flexible waterproof material is coated. The protective coating is particularly suitable for the concrete powdering and remediation under high and cold conditions (-40 DEG C), and the protective coating has the characteristics of water immersion resistance, freeze-thaw resistance, low temperature resistance, ultraviolet resistance and the like. The construction process is simple, the service life is long, and the goals of safety, convenience, environmental protection and durability are achieved.

Description

technical field [0001] The invention relates to the technical field of concrete protection and treatment, in particular to a protective coating for concrete pulverization and treatment and a construction method thereof. Background technique [0002] Due to reasons such as design, construction, management and operation of concrete, such as cavitation, abrasion, erosion, freeze-thaw, water chemical erosion or mechanical impact, the surface layer is damaged and pulverized. If it is not treated, it will directly affect the concrete. The structure is safe, so it is urgent to remediate the pulverization of concrete. In alpine regions (-40°C), protective materials must withstand the effects of complex climate environments such as blisters, freeze-thaw, low temperature, and ultraviolet rays. At the same time, problems such as the service life and durability of protective coatings need to be solved. [0003] At present, the main properties of domestic polymer cement waterproof coati...
