Baihua's treatment: Apply protective treatment on the surface of the stone and strengthen the waterproof function of joint filling. Treatment of rust spots: Using Shidafu stone rust remover can effectively remove rust spots without damaging the stone. This is the remedial method later. In fact, it is still necessary to do a good job of stone maintenance before installation, so that rust ions cannot penetrate into the interior of the stone with water, and then the rust spots will have nowhere to land. Treatment of stains: Choosing appropriate stone specific cleaning agents can effectively remove them. For example, oil stains can be treated with Stone Doctor's grease, and pigment stains can be treated with Stone Doctor's pigment treatment agent. Wax scale treatment: Using a cleaning wax remover can effectively remove wax scale from the surface and capillary pores of stone without damaging the luster of the stone.

Construction preparation
1. Quality management at the construction site should have corresponding construction technical standards, a sound quality management system, construction quality control, and quality inspection systems. Before grouting, there should be a construction organization design or construction technical plan, which should be reviewed and approved.
Before grouting construction, mixing equipment, grouting devices, templates, and maintenance items should be prepared.
3. In addition to complying with the relevant provisions of the current national standard "Code for Acceptance of Construction Quality of Concrete Structures" GB 50204, formwork support should also comply with the following regulations:
① During secondary grouting, the horizontal distance between the formwork and the equipment base should be controlled at around 100mm; The top elevation of the template should not be lower than 50mm above the surface of the equipment base.
② When renovating and reinforcing concrete structures, sufficient grouting holes and exhaust holes should be left in the formwork support. The diameter of the grouting holes should not be less than 50mm, and the spacing should not exceed 1000mm. The grouting holes and exhaust holes should be 50mm higher than the high point of the holes.

Volcanic rock refers to small hills of different shapes formed by the eruption of hot gases, liquids, and solids from a volcano, which then fall to the ground and accumulate. Due to the rapid decrease in temperature and pressure caused by the gas slag and solid magma produced during the eruption, chemical and physical changes occur, resulting in the magma becoming volcanic rock. This substance rises along the cracks caused by the uplift. When the pressure in the lava chamber exceeds the pressure of the rock cap above it, it erupts outward and becomes a volcano. During an eruption, hot gases, liquids, or solid substances suddenly emerge. These substances accumulate around the opening, forming a conical mountain top.

construction method
▲ Mixing
When mixing cement-based grouting materials, water should be added according to the required amount of water for the product.
2. Cement based grouting materials should be mechanically mixed. When mixing, it is advisable to first add 2/3 of the water and mix for about 3 minutes, then add the remaining amount of water and mix until uniform. If there are specific mixing requirements for AGM-340 products, they should be mixed according to their requirements.
3. The mixing site should be close to the grouting site.
▲ Anchor grouting of foundation bolts
1. The construction process of anchoring anchor bolts should meet the following requirements: ① Cleaning hole 1 ② Cleaning accumulated water in the hole 1 ③ Removing oil stains and rust on the surface of the bolt 1 ④ Inserting bolt adjustment and fixing 1 ⑤ Mixing AGM-340 grouting material 1 ⑥ Building 1 ⑦ Maintenance 1 ⑧ Installing equipment.
When drilling anchor bolts, the horizontal deviation of the bolt holes shall not exceed 5mm, and the vertical deviation shall not exceed 5 °. The wall of the bolt hole should be rough, and the hole should be cleaned thoroughly without any floating dust, oil stains or other impurities. Before grouting, soak it in water for 8-12 hours to remove any accumulated water in the hole. When the ambient temperature is below 5 ° C, measures should be taken to preheat and maintain the temperature above 100 ° C.
Before grouting, the oil stains and rust on the surface of the anchor bolts should be removed.
When pouring the mixed cement-based grouting material into the bolt holes, the position of the bolts can be adjusted as needed. Vibration is strictly prohibited during the grouting process, and bolts cannot be adjusted again after grouting is completed.
5. The upper surface of the grouting layer inside the hole should be about 50mm lower than the surface of the foundation concrete.

Try not to purchase marble from "mobile booths" as many of them are dyed and the hygiene and safety of the coatings are questionable. When selecting on site, there are three methods: visual observation, auditory observation, and ink dripping. Eye view: Stone with a uniform fine structure has a delicate texture, making it an excellent product for stone; The appearance of coarse-grained and unevenly structured stone is poor. Ear listening: The sound of high-quality stone striking is crisp and pleasant; If there are slight cracks inside the stone or if the contact between particles becomes loose due to weathering, the knocking sound will be rough and hoarse. Dripping ink: Drop a small particle of ink on the back of the stone. If the ink quickly disperses and leaches out, it indicates that the particles inside the stone are loose or there are gaps, indicating poor quality of the stone; If the ink drops in place and does not move, it indicates that the stone texture is good.
▲ Secondary grouting
The appropriate grouting method should be selected for secondary grouting according to the actual situation of the project. The process flow should meet the following requirements: ① Cleaning the equipment foundation ② Soaking in water 24 hours in advance ③ Clearing accumulated water before grouting ④ Preparation of construction equipment ⑤ Mixing AGM-340 grouting material ⑥ Secondary grouting ⑦ Curing.
Before grouting, the equipment base plate and concrete foundation surface in contact with the grouting material should be cleaned thoroughly, and there should be no loose crushed stones, floating slurry, oil stains, wax, etc. 24 hours before grouting, the surface of the foundation concrete should be fully wetted, and the accumulated water should be removed 1 hour before grouting.
During secondary grouting, grouting should be carried out from one side until it overflows from the other side, and grouting should not be carried out simultaneously from opposite sides. After grouting begins, it must be carried out continuously and the grouting time should be shortened as much as possible.
When the track foundation or grouting distance is long, it can be constructed in sections according to the actual engineering situation.
5. Vibration is strictly prohibited during the grouting process. If necessary, a grouting booster should be used (pushing the grouting material along the bottom of the grout flow direction, and it is strictly prohibited to push it from the middle or upper part of the grouting layer).
After the equipment foundation grouting is completed, it is advisable to cut a 45 ° angle outward along the edge of the bottom plate 3-6 hours after grouting.

Then add up all the G values and take the average. Then add up all the B values and take the average. The average of the total R values above is called the R value, the average of the total G values above is called the G value, and the average of the total B values above is called the B value, forming a color. Then, this color is painted all over the circle, forming a mosaic. Mosai, a professional term in architecture, is divided into two types: ceramic mosaic tiles and glass mosaic tiles. It is a decorative art that usually uses many small stones or colored glass fragments to form patterns. In church glassware, it is also known as stained glass.
