Abstract

The invention relates to a multifunctional anti-leakage shrinkage type concrete surface layer reinforcer which is prepared from the following components in percentage by weight: 10-20 percent of high polymer, 1-7 percent of film forming aided compound, 5-10 percent of surface layer active agent compound, 1-4 percent of leakage aided compound, 1.5-4.5 percent of active compound and the balance of water. The invention has good concrete surface layer enhancement effect, can obviously reduce the shrinkage of surface layer concrete, obviously improves the carbonization resistance and the medium leakage resistance of surface layer concrete, has convenient construction and obvious economic benefit and can be widely applied to the strengthening treatment operations on the surface layers of cement and concrete pouring components, concrete components under corrosion environment conditions such as piers, dams, and the like and deformed concrete components difficult to be strengthened by adopting a conventional method.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a multifunctional anti-seepage and shrinkage-reducing concrete surface layer strengthening agent. Background technique [0002] The quality of concrete surface structure is related to the development of concrete strength and its own durability. High-quality surface structure plays a vital role in improving the performance of concrete and the stability of the overall structure. Concrete surface strengthening technology is one of the important ways to improve the performance of concrete surface. [0003] The main ways to strengthen the concrete surface are to strengthen the concrete surface by water curing and heat and humidity curing, to cover the concrete surface with a film or spray curing agent, and to use a concrete surface strengthening agent. However, not all projects can ensure that the concrete surface has long-term water curing and humid heat curing conditions. ...
