The color, pattern, and texture of natural stone are subjective factors in the selection process, often varying according to the preferences of the owner and designer. However, if one can have a deeper understanding of natural stone, make reasonable combinations of colors such as yin and yang, brightness and darkness, softness and hardness, and warmth, and then design unique construction drawings based on this, the decorative value of natural stone can be more fully reflected. Natural stone belongs to natural ores, and different natural stones have significant differences in price due to their quality, quantity, mining location, processing technology, and other factors. This requires the owner and designer to choose the corresponding natural stone according to the project budget.

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.

The radioactivity in nature cannot be avoided, so only the 4% of materials used in human production and daily life can be controlled. Stone, as a production and living material, should also be included in the scope of controlled use. Controlling the use of stone does not necessarily mean controlling the use of all types of stone. In the national standard "Limits of Radioactive Nuclides in Building Materials" (GB6566-21) jointly developed by the National Building Materials Testing Center, the Institute of Building Materials Science, the Industrial Hygiene Laboratory of the Ministry of Health, and the University of Geosciences (Beijing) at the end of 2021, it was stipulated that only the radioactivity of granite should be tested. This is because 49456 monitoring points and 66526 residential buildings were observed during the development of this standard, and 1993 batches of product testing were also conducted. Referring to the testing data of stone materials over the years, especially the experience and data of controlling stone materials, it was found that the radioactivity of marble, slate, artificial stone, sandstone, synthetic stone, and recycled stone were within the safe range, with only a small portion of them being tested. The radioactivity of granite exceeds the standard.

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.

Gemstone Brown is an imported granite produced in Brazil, with the English name "Materous". The base color is brown, and the surface texture is obvious but uneven. Medium coarse grain flow like crystals are embedded on its surface, which is clear and distinct, showcasing an elegant and unique style. Features: Hard texture, dense structure, good weather resistance, and can be used outdoors for a long time. Advantages: Natural texture, elegant and noble, low radioactivity, uniform water absorption, resistance to weathering and pollution. The characteristics of gemstone brown granite also include high bearing capacity, compressive strength, and good grinding ductility. It is easy to cut and shape, and can create thin and large plates. Generally used for floors, steps, bases, treads, eaves, etc., it is mostly used for decoration of outdoor walls, floors, columns, etc.
▲ 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.

The thin plastering external wall insulation system is currently the insulation system used in the domestic market, also known as the External Wall Insulation Decoration System (EIFS). Expanded polystyrene board and polystyrene particle insulation slurry are two commonly used insulation materials. For this insulation system, external water and moisture can enter the system through different pathways. A survey has been conducted abroad on the infiltration locations of water and moisture in this system, and the results show that 45% of cases occur under windows, 3% occur at the connection between roofs and walls, 1% occur under terraces, 6% infiltrate from the exterior walls of the insulation system, and 9% infiltrate due to other reasons such as penetrations.
