Terrazzo flooring is a composite flooring material made of cement as a main raw material, has the advantages of low cost, moisture resistance and good usability, and is widely used in hospitals, pharmacy, machinery, government offices, schools, commercial places, airports, stations, wharfs and other public buildings with very large areas. After the concrete is initially set and before the concrete is finally set, the surface of the concrete needs to be polished, the surface constructed by a machine is smoother and flatter than the surface constructed manually, the compactness and the wear resistance of the surface of the concrete can be greatly improved, and important machines and tools in the concrete construction of a troweling machine can be widely used for slurry lifting, troweling and polishing of the concrete surface of high-standard factory buildings, warehouses, parking lots, squares, airports and frame type buildings.

The grinding time of the terrazzo ground surface finishing is related to the cement paste strength and the air temperature, when the cement paste strength is too high, the grinding surface consumes working hours, and when the strength is too low, the negative pressure generated on the bottom surface is easy to pull the cement paste into a groove or knock off stone grains when the terrazzo rotates. The large-area construction is preferably ground by a mechanical smoothing machine, and water is usually arranged below a smoothing head during grinding to wash and timely clean the ground stone slurry. In addition, the concrete surface is easy to dry in severe weather such as strong wind, high temperature, dryness, insolation and the like, and the concrete surface is cracked when being pressed in an impressing artistic terrace; particularly, in the outdoors, the surface of concrete is easy to dry in the place exposed to sunlight, so the difference of the solidification degree is large, and holes are easy to appear on the surface of concrete; in addition, the water spraying can also effectively reduce the temperature of the troweling blade in the troweling operation so as to prolong the service life of the troweling blade and prevent the dust from rising and being absorbed by human bodies to damage the health of operators. Therefore, the concrete is required to be sprayed with water in the finishing process so as to quickly finish the holes on the surface of the concrete, so that the concrete is consistent in solidification degree, the integral integrity of the concrete is kept, the cracking phenomenon is effectively reduced, and the finishing quality effect is improved.
