Concrete rough surface processing agent and its preparation method and application

The invention discloses a concrete matte surface treating agent and the preparation method and application thereof, the agent is prepared by neutral or alkaline solution, bond earth and water, the natural or alkaline solution is prepared by the neutralization reaction between the lemon acid solution and the carbonate solution and the pH value is 7-8.5. The preparing method comprises the followingsteps: preparing neutral or alkaline solution; adding bond earth and water into the solution and mixing to uniform; inputting the mixture into a distillation container for reacting, distilling and the powder preparation is prepared after crushing and sieving. And the application comprises the following procedures: preparing the mixed serum; preparing the powder preparation with water by weight and mixing; before the primary agglomerating of the surface of the concrete to be processed coating the mixed serum thereon; and finally flushing with the pressure water when the concrete has agglomerated for seven days.
