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.

Solution: Clean the debris and enhance the chip removal effect; Adjust or replace the flange; Install correctly according to the instructions. Reason for blade damage: The blade bonding agent is too hard; The feed speed of the saw blade is too fast. Solution: Choose a saw blade with a softer bonding agent based on the material being cut; Reduce the feed rate of the saw blade. Reason for rapid wear of the cutting head: the bonding agent of the cutting head is too soft (for the material being cut); Insufficient cooling water volume; Insufficient power caused by loose drive belts, low voltage, or inappropriate rotational speed; The saw blade is not perpendicular to the material being cut. Solution: Choose a saw blade with a harder bonding agent based on the material being cut; Check the cooling water system to ensure the normal operation of the water pump; Ensure the supply voltage; Check the spindle flange to ensure the verticality of the saw blade and equipment; Check the speed of the saw blade.
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.

In recent years, with the improvement of people's living standards, the popularization of stone paving, and the development and promotion of stone care technology, stone renovation and care are gradually being understood by people. Many people realize that stone is a form of care and can be renovated. We often talk about the need for renovation of stone materials. After renovation, the stain resistance of the stone will be enhanced, the glossiness will be improved, and the mirror effect will be better. Do all stones need to be renovated? Which stones need to be renovated? Firstly, not all stones need to be renovated. If the stone has not been used for a long time and has not undergone any changes or pollution, there is no need for renovation. Regular maintenance and cleaning can ensure that the stone remains clean and beautiful.
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.
The main components of environmentally friendly decorative materials for soft porcelain exterior walls are soil, which has good weather resistance. The developed polymer also has good aging resistance, and a small amount of antifreeze agent is added as needed to achieve good weather resistance for soft porcelain exterior wall environmentally friendly decorative materials. After testing, the environmentally friendly decorative material for soft porcelain exterior walls showed no signs of damage such as cracks after 2 hours of artificial climate aging and artificial radiation exposure experiments (25 hours is considered qualified according to the exterior wall coating standard); After one repeated freeze-thaw cycle (ceramic tile standard only requires 5 cycles), there are no cracks, peeling or other phenomena; In addition, after soaking in 3% or 3g/L potassium hydroxide for 8 hours, there was no foaming or peeling phenomenon.
