Technical Field
The invention relates to the technical field of building material maintenance, in particular to a concrete surface carbonization-resistant curing agent and a preparation method and application thereof.
Background
After concrete is poured, if the concrete is maintained in hot weather and air drying in time, water in the concrete can be evaporated too fast to form a dehydration phenomenon, so that cement particles which form gel cannot be fully hydrated, cannot be converted into stable crystals, and lack of sufficient cohesive force, and then flaky or powdery falling can occur on the surface of the concrete. Further, when the concrete does not have sufficient strength, premature evaporation of water causes large shrinkage deformation and cracks due to drying shrinkage. Therefore, the curing of the concrete in the initial stage after the concrete is poured is very important, the curing should be performed immediately after the concrete is finally set, and the curing should be performed immediately after the pouring of the hard concrete is completed.
The concrete curing agent is also called concrete protective agent and concrete curing liquid, and is emulsion or polymer solution which is sprayed or painted on the surface of concrete and can form a layer of continuous waterproof sealing curing film on the surface of the concrete.
In the aspect of concrete curing agents, the research in China is late, the preparation of raw materials is less, and the performance of the curing agents is uneven. Although considerable scholars have studied the curing agent at home and abroad and have achieved a series of achievements, the current research still has shortcomings and defects.
The formula of the common concrete surface curing agent is single in component, mainly the concrete surface is subjected to moisture preservation and curing, the defects of single curing effect, low curing efficiency of the curing agent, poor surface carbonization resistance effect and the like exist, so that the urgent need is to develop a concrete surface curing agent with curing and carbonization resistance, the novel concrete surface carbonization resistance curing agent can improve the durability and the service performance of building materials, and favorable conditions are provided for increasing the market competitiveness of the building material industry.
