The surface of quartz stone slabs is not treated in a special way, but is polished by more than thirty high-pressure rapid water mills. Once used at low speed, it will cause whitening and discoloration. A common problem in quartz stone installation joints is that two boards appear high or low, and the treatment method often involves polishing, which can cause the surface of the board to lose its luster. So in the seamless splicing process, it tests the level of the installation master. Qualified and high-quality quartz stone is produced using die-casting technology, with a density of up to 2.46g/cm3 and a water absorption rate of. 2%, which is relatively good in terms of anti-seepage. However, some unqualified quartz stone products may seep into contaminated impurities during daily use, affecting their appearance.

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.

The designer is not familiar with the application of new material blocks. The design unit is still in the process of understanding and exploring the performance of new material blocks and the application of new standards, so there are more or less design defects. Mainly, non load bearing concrete block walls are backfilled and enclosed structures. When the size of the wall does not match the specifications of the blocks, it is difficult to completely fill it with blocks, resulting in large pores at the connection between the masonry and the beam slab column of the concrete frame structure, which is prone to cracking; The areas such as door and window openings and reserved hole edges are stress concentration zones. Without effective reinforcement measures, cracks may occur due to impact vibration; The wall thickness is too small and the strength of the masonry mortar is too low, resulting in insufficient rigidity and easy cracking of the wall; Installing pipelines or hanging heavy objects through wall openings can cause deformation and cracking of the wall; The wall in contact with water did not consider structural measures such as waterproofing, drainage, flashing, and dripping, resulting in wall leakage.

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.

Although stone washbasins are noble, beautiful, and unique, they are also very prone to contamination due to the gaps in the stone itself. So cleaning stone washbasins has become a compulsory course for every stone washbasin user. So how to remove stubborn stains on stone washbasins?? Actually, it's not difficult either. As long as you follow the steps below to clean, you can give the washbasin a shiny appearance. Firstly, we can use a neutral stone cleaner. If neutral cleaning agents are ineffective, you can try using cleaning agents with stronger cleaning properties. However, it is important to distinguish the original properties of the stone and which chemicals it will react with. For example, marble requires sexual detergent, while granite requires sexual detergent.

Different types of marble floor tiles actually help determine where to install and their intended use. The quality of bricks and their naturally beautiful appearance help create a range of different types, colors, patterns, and textures of marble brick combinations. One type of tile is glazed tile or unglazed tile. Glazed marble tiles help improve their waterproof performance because their surface is very hard and smooth. This also makes this type of marble brick easy to clean and maintain. This type of marble brick also does not require waxing, as its surface is very hard and can maintain its natural luster without the need for external forces. Make small decorative pieces using their natural form, and lay them on indoor and outdoor floors, walls, and park walkways. Paired with color tones and floral patterns, it feels more natural, beautiful, and pleasant. Many marble factories use leftover marble edges and corners that meet their industrial requirements to make electrical switch boards, distribution panels, light switches, etc., and their products are very popular. Used for producing mosaic materials and ice patterned marble mosaic stones, it is a process of bonding small tiles of different colors and geometric shapes into large-sized boards with various patterned patterns; Ice patterned marble is a large-sized board made by directly splicing different colored scraps with their natural edges, resembling ice blocks thawed by the Spring River.
