Winter construction

When the daily average temperature is below 5 ° C, winter construction should be carried out and meet the following requirements:
1. Before grouting, measures should be taken to preheat the foundation surface, keep its temperature above 100 ° C, and remove accumulated water.
Before being frozen, the compressive strength of cement-based grouting materials shall not be less than 5MPa.

When laying artificial stone on the ground, it is necessary to arrange reserved joints according to the specific size of the ground to be laid. The width of this reserved joint should be between 1.5-3mm, and the joint should be filled with sealant, such as WF-82 flexible sealant for the ground. Why can't sexual cleaning agents be used? Generally, artificial stone contains over 92% natural marble, which is a metamorphic rock of limestone and mainly composed of carbon and calcium. Therefore, non neutral substances can damage its luster. Cleaning agents sold on the market often use sexual substances as raw materials to achieve cleaning effects, and long-term use can result in a decrease in the luster of artificial stones. It is recommended to stay away from non neutral items such as diluents, tile cleaners, etc.
Construction in high temperature climate environment
If the temperature of the grouting site is greater than 35 ° C, construction should be postponed according to the high temperature climate and meet the following requirements:
Measures should be taken 24 hours before grouting to prevent direct or other thermal radiation from the grouting area.
2. Take appropriate cooling measures, and the temperature of the concrete foundation and equipment base plate in contact with the cement-based grouting material should not exceed 35 ° C.
3. The injection temperature of the slurry should not exceed 30 ° C.
4. Moisturizing and curing measures should be taken promptly after grouting.

Stone is widely used in construction and home decoration, but natural stone is expensive and limited in quantity. And artificial stone precisely compensates for these shortcomings, becoming a substitute for natural stone and widely used in various places. The correct use of artificial stone: Do not place high-temperature objects directly on the countertop. When placing high-temperature objects, other insulation materials such as brackets with rubber feet and insulation pads should be added under the placed objects; Do not immediately boil the cabinet countertop with hot water after rinsing it with cold water, as this may cause the artificial marble countertop to explode due to sudden cooling and heating in a short period of time; Do not drag heavy objects directly on the countertop to maintain a smooth and beautiful appearance; Do not use the countertop as a cutting board to directly cut or chop various items; (Tip: Add a rubber anti slip pad or towel under the cutting board) Do not let heavy objects or sharp objects impact the surface of the artificial stone to prevent leaving marks; Avoid contact between the countertop and some organic solvents, such as paint removers, polish remover, and looseness, which may damage the gloss and smoothness of the countertop and cause stains.

The maintenance free construction conditions are as follows

When the construction temperature is above 5 ℃ and below 35 ℃, there is no need for maintenance after foundation grouting. If the temperature exceeds the range, the grouting material construction and maintenance methods should be followed for maintenance.

Both natural and artificial stone have gradually become a widely used type of building stone products in the modern construction industry, and both natural and artificial stone products are inevitably prone to weathering during use; The weathering of stone usually refers to the erosion caused by various factors in the natural environment, which leads to the disintegration of stone, especially for outdoor decoration. Once weathering occurs, the service life will be shortened. So, how to prevent the weathering of stone during its use? We need to start discussing the factors that cause stone weathering. The function of lower plants: Under suitable conditions of water and temperature, spore sacs of organic matter such as moss and mold attach to the surface of stone and begin to develop and grow, forming various organic color spots on the surface of the stone. These organic matter fight against substances such as carbon and nitrogen in the air in order to survive, changing the surface texture structure of the stone.
