[0077]

[0078]

[0079] According to the performance test and color comparison of the samples of Example 1 to Comparative Example 3, it can be seen that the compressive strength and wear resistance are not much different.

From the comparison of the samples of Example 1 and Comparative Example 1, it can be seen that in the preparation method, the curbstone that has not been finely water-ground has a poor color and a rough surface. After being exposed to wind, sun and rain, the glaze has a high degree of degradation, severe fading, dullness, and poor glaze color and life. From the comparison of the samples of Example 1 and Comparative Example 2, it can be seen that the curbstone that has been finely water-grinded for only one time has ordinary color and a slightly rough surface. After being exposed to wind, sun and rain, the glaze surface is highly degraded and severely faded, losing its original gloss and cannot maintain the integrity of the glaze surface. From the comparison of the samples of Example 1 and Comparative Example 3, it can be seen that the curbstone that has been finely water-grinded for only two times has improved color and surface, but after being exposed to wind, sun and rain, the glaze surface is degraded, the color and gloss are faded, and the glaze surface cannot remain intact.
