Polymer cement adhesive construction method

Abstract

The invention relates to a polymer cement adhesive construction method, which belongs to the civil engineering field. The method comprises the following steps: (1) clearing dirt on the concrete surface, treating the base surface, sprinkling water on the concrete surface and keeping the concrete surface to be wet; (2) evenly mixing and stirring ordinary polymer emulsion and cement in a proportion of 1:2, timely painting and brushing after polymer cement adhesive is mixed, wherein the thickness of the painting and brushing is in a range of 0.5mm-1mm; and (3) beginning to pour concrete when the surface of the polymer cement adhesive solidifies and is no longer sticky, wherein the time that the polymer cement begins to solidify is related with temperature, wind-force, humidity and the like. The construction progress is quicker by using the method compared with common methods, and material sources are abundant. The construction is safer, and the economic benefit is good. The process is simple and can enable the concrete of different pouring dates to be combined well, no construction cold joint is generated, and requirements of construction devices are simple and convenient. The construction pollution is small, thereby facilitating environmental protection and health of construction operating workers.

Description

technical field [0001] The invention relates to a polymer cement adhesive construction method, which belongs to the field of civil engineering. Background technique [0002] In recent years, in domestic civil engineering construction, the second phase of concrete pouring, renovation of old concrete structures and cold joints caused by construction projects are very common. The combination of concrete is usually constructed by chiseling the concrete surface. This method is very difficult to construct, especially for high-strength concrete, which wastes a lot of manpower and material resources, and the construction period is also long. The dust during construction is large, which pollutes the construction environment, seriously damages the physical and mental health of construction workers, and the construction is dangerous. . Contents of the invention [0003] The purpose of the present invention is to provide a simple, easy on-site operation, environment-friendly and safe...
