Within the size range, the support property of the support aggregate to the grinding stone material can be ensured, and the flatness of the ground can also be ensured. Since the mechanical strength of quartz and crystal is higher than that of glass, the mesh number of quartz and crystal can be larger than that of glass in terms of material selection, that is, the strength equivalent to that of glass aggregate can be achieved when the external dimensions of quartz and crystal are smaller than that of glass.

and hardening the surface, spraying a hardening agent, and spraying the hardening agent on the surface of the grinding stone layer after the surface polishing step is finished to form a cured layer.
6. The method of claim 5, wherein between the steps of paving concrete and spreading the stone material, the method further comprises:
leveling concrete, namely leveling a concrete foundation layer by using a light collecting tool, and extracting slurry on the surface of the concrete in the repeated leveling process to form a concrete leveling layer; and
and (4) secondary slurry lifting, namely when the concrete is in the initial setting process, troweling and lifting the slurry on the surface of the concrete leveling layer by using the mechanical disc, and simultaneously removing redundant slurry floating to form a concrete surface layer.
7. The method of claim 5, wherein the step of scattering the grinding stone material comprises:
dividing the spreading areas according to construction requirements, determining the specification of supporting aggregate selected by each spreading area, and calculating the using amount of the supporting aggregate required by each spreading area, wherein,
The weight of the required grinding stone material per square meter of the spreading area is 10kg-15kg, and the weight of the required grinding stone material per square meter is proportional to the specification of the supporting aggregate.
8. The method for integrally constructing a grinding stone material and concrete according to claim 5, wherein in the step of spreading the grinding stone material, the grinding stone material is divided into three equal parts and spread three times, the criss-cross spreading is adopted for two adjacent times, the time interval between the two times of spreading the grinding stone material is 20min to 60min, and the step of rubbing and smearing is performed after each time of spreading the grinding stone material.
9. The method of claim 5, wherein after the step of hardening the surface is completed, the method further comprises:
surface curing, spraying water to the cured layer within 24 hours after the surface hardening step is completed, and spraying a concrete curing agent daily within 7 days after the surface hardening step is completed; and
and (4) surface polishing, namely spraying a liquid densification agent on the solidified layer, and grinding and polishing the solidified layer by using a grinder.
10. A grindstone terrace, characterized in that, the grindstone terrace is obtained through the construction method of any one of claims 6 to 9, and the grindstone terrace includes concrete foundation layer, concrete leveling layer, concrete surface layer, grindstone layer, and cured layer that stack up in proper order from bottom to top.
