Edit this paragraph for reference usage
The reference usage calculation is based on tons/cubic meter to calculate the actual usage.
It is precisely because the strength of the grouting material is high, far exceeding the strength that cement can achieve, and it changes the shrinkage characteristics of cement during solidification, so it is called high-strength non-shrinkage grouting material! !
There are different types of grouting materials, such as grouting materials, high-strength non-shrinkage grouting materials, etc. These are determined according to the standards of different architectural research institutes and do not represent the quality of the product. The specific usage conditions require test.

Edit the construction steps of this section
Prepare mixing machines, grouting equipment, templates and maintenance items, clean the grouting space and wet the concrete surface in advance.
, Set up the formwork and seal the joints of the formwork with cement (sand) slurry and plastic tape to ensure no water or slurry leakage.
Add water and stir according to the weight of the grouting material (mechanical stirring for 10 minutes, manual stirring for more than 10 minutes)
Pour the evenly stirred grouting material into the grouting part from one direction. If necessary, bamboo strips or steel drills can be used to guide the flow, and the template can be properly vibrated or lightly tapped.
. After the construction is completed, it should be covered with plastic film immediately and covered with straw curtains or quilts for 3 days of moist curing.
, The operating temperature is -℃ to ℃. It is strictly prohibited to mix any additives or external additives into the grouting material.
Edit this paragraph Construction and maintenance
Normal temperature maintenance
Before grouting, the daily average temperature should not be lower than ℃. After grouting, the exposed parts should be sprayed with curing agent or covered with plastic film in time, and covered with wet The straw bag stays moist. When covered with plastic film, the exposed surface of the cement-based grouting material should be covered tightly to keep condensation water in the plastic film. If it is inconvenient to water the surface of the grouting material, a curing agent can be sprayed.
.The grouting material should be kept in a moist state, and the curing time should not be less than.
3. When using fast-setting and fast-hardening cement-based grouting materials, maintenance measures should be carried out according to the methods required by the product.
High temperature maintenance
. Take measures before grouting to prevent the grouting parts from being exposed to direct sunlight or other thermal radiation.
.Take appropriate cooling measures, and the temperature of the concrete foundation and equipment floor in contact with the cement-based grouting material shall not exceed 3℃.
3. The temperature of the slurry entering the mold should not be greater than 3°C.
. Moisturizing and maintenance measures should be taken promptly after grouting.
Winter maintenance
. During winter construction, if the project does not have special requirements for strength growth, the exposed parts should be covered with plastic film and insulation materials in time after grouting is completed. The initial curing temperature should not be lower than ℃. Do not water when curing under negative temperature conditions.
.After the formwork is removed, if the difference between the surface temperature of the cement-based grouting material and the ambient temperature is greater than ℃, it should be covered and protected with insulation materials.
3. If the ambient temperature is lower than the minimum construction temperature required for cement-based grouting materials or the strength growth needs to be accelerated, artificial heating maintenance can be used. The maintenance measures should comply with the relevant provisions of the current national standard "Construction Regulations for Winter Period of Construction Projects" . []

Construction instructions
The pulping process must use the - type developed by Hubei Zhongqiao Technology Co., Ltd. For high-speed pulping machines, first add an appropriate amount of water to clean the equipment and at the same time wet the barrel wall. Then add water to the scale position of the pulping machine, turn on the mixing pump and circulation pump, and add 3 (packs) of grouting material at a constant speed. The pulping machine should be in working condition during the feeding process. After the feeding is completed, stir for 3~ and introduce the slurry into the storage bucket. Stir until slurry is complete.
