How Should The Bluestone Slabs Be Used During Construction

Similar to the construction method of other granite and other stone, the construction method of the green stone slab paving stone is as follows:
1. Consolidate the soil layer at the bottom, spray some water appropriately in the process of consolidating, and repeatedly consolidate.
2. Filter the bluestone slab and observe the whether there are cracks on the surface of the stone. If it is dried half dry after spraying the water on the surface of the bluestone, there is still a long water line without drying, then this water line is generally cracks. The corner of the compilation is generally less than 5mm-10mm, and the ratio is not more than 5%-10%of the total number. For projects with strict requirements, the diagonal of the bluestone slab is required. The length of the line should be less than 1mm-2mm to determine that the angle of the four sides is 90 degrees right angle.
3. Pour cement mortar on the solid soil layer. The ratio of sand and cement is 3: 1. The thickness of the cement mortar is generally higher than the thickness of the bluestone slab.
4. Do a good job of the horizontal line, the height of the horizontal line is consistent with the surface height of the upper surface after the completion of the bluestone slabs.
5. Press the green slate on the cement mortar. The paved slate should be consistent with the horizontal line, and then lift the slate to observe the contact effect. If the contact area is less than 90%, it should be paved on the cement mortar. Flat and lay slate, you can repeat it a few times until the slate and cement mortar are fully exposed. After 12 hours after laid, it can be loaded.
