Roughening method of concrete
The invention provides a roughening method of concrete. The roughening method comprises the following steps: 1) pouring concrete, and leveling a surface so as to obtain a concrete layer; 2) uniformly bestrewing rough quartz sand adhered with a high-strength mortar material on the surface of the leveled concrete layer; 3) finally setting for 48 hours later, performing curing by adopting high-temperature steam, wherein the curing temperature is 70-90 DEG C, and the curing time is 48-72 hours, so that the concrete with a rough surface is obtained. According to the roughening method disclosed by the invention, the concrete layer is not destroyed, besides the rough surface formed on the surface of the concrete layer has the characteristics of fastness and reliability, and the binding effect of the concrete prepared by the roughening method and asphalt concrete is much better than that of concrete prepared by conventional technologies of groove notching and the like and the asphalt concrete.
