The glossiness of stone depends on the reflectivity of various minerals that make up the rock, and is closely related to the microstructure of the surface of the decorative stone, that is, the quality of the stone surface processing. For natural stone, the smoothness of the stone surface varies depending on the composition of minerals. Overall, the smoother the surface, the better the reflection effect (light reflectivity) of the stone, and the fewer concave and convex defects on its surface, resulting in a higher glossiness of the stone. Due to the generally fixed mineral composition of natural stone, with only slight variations in specific composition ratios and trace element content, the luster of stone is basically determined by its material.

When high-strength road repair materials are applied to road surface repair, a lot of things need to be mixed in order to achieve strength. Although high-strength road repair materials have high strength, they are relatively brittle overall. In this case, it is recommended to add steel fiber high-strength road repair materials during the mixing process, which can produce buffering under huge pressure.  

Secondly, it is necessary to choose high-strength road repair materials that solidify quickly and reach strength within 2 hours, because during road repair, it is necessary to open to traffic in a short period of time.

Then, when selecting steel fibers, it is important to pay attention to the proportion of addition, which depends on different situations, such as high-strength road repair materials and steel

Please refer to the guidance of technical personnel from the grouting material manufacturer for the proportion of fibers.

Waterproof quick setting agent can quickly set cement, and the setting time can be adjusted arbitrarily, from tens of seconds to minutes, controlled by the dosage. The cement mortar or grout mixed with this product has strong adhesion to bricks and concrete, and can be used in wall and floor sealing, anti-seepage and other engineering projects. Usage of waterproof quick setting agent: Block water leakage cracks and holes: Waterproof adhesive should be prepared, with a setting time of about 4 seconds. Use your hand to sew (hole) and release it after it solidifies. Five layers of waterproof plastering layer with one layer of plain plaster, cement: water: waterproofing agent is 1:.3~. 35:1. First, apply a layer of plain plaster with a thickness of 1mm, press it 5-6 times with an iron trowel, then level it with plain plaster to a thickness of about 1mm, and then dip it in water with a brush, brush it evenly in order, and immediately apply the second layer.

Steel fibers need to be added during the mixing process to ensure even mixing.

Cleaning the road surface:

1. The road surface needs to be cleaned thoroughly and there should be no debris

2. Need to carve out a certain height for grouting

3. Need maintenance, watering and moisturizing the road surface

4. After the road repair, it will be open to traffic in about 2 hours.

Glass rock wool insulation board has certain detail requirements during installation. We must pay attention. Design the laying method for the glass wool board before use. Calculate the size and cut the material. The straight line error of the cutting edge should be less than 5mm, and the joint should not exceed 2mmm. The gap between the boards should be bonded with special tape. The glass wool board should be laid from top to bottom and connected to each other. The glass wool board should be laid in order, and when encountering door and window openings, it should comply with the requirements of the relevant atlas. After the fireproof and non combustible glass wool is laid, check the anchoring points, flatness, and bonding quality between the connected panels of the glass wool board. Only after passing the inspection can dry hanging stone work be carried out. Plate surface anchoring and surface treatment anchoring: The installation depth of the insulation board anchoring device into the structural wall shall not be less than 25mm.

The rocky land of the Taihu Lake Lake is relatively loose, and the stone quality of the two is naturally poor. As for the Banna stone, its hardness is only 4 degrees. Although its shape has also changed slightly, but it is closer, it clearly feels that its stone is loose and fragile, which is different from the the Taihu Lake stone. In addition, some rocks have coarse crystals, which are not smooth or clean due to the diffuse reflection of light by each crystal surface. The same applies to pebbles. Some pebbles (referred to as "Rain Flower Stones" in the following chapter) contain agate, which is hard and dense, giving them a smooth and lovely appearance. Most pebbles are composed of limestone, sandstone, and metamorphic rocks, with relatively rough texture.
