High-strength non-shrinkage grouting material should pay attention to these matters during use.

1. Grouting base surface treatment.

1. The grouting base surface should be kept on the rough surface, the bonding strength should be improved, and the hair should be chiseled as much as possible.

2. Clean the surface dust, gravel, and no oil stains.

3. The day before grouting, water should be soaked and soaked, and the stagnant water should be cleaned up before grouting.

Second, grouting formwork.

1. According to the grouting position according to the drawing formwork, there can be no gaps, holes, and the gap and bottom of the template are closed with foaming agent or tape to prevent slurry leakage.

2. The template should be higher than the grouting surface to facilitate grouting .

3. If leakage is found in the grouting, the grouting should be stopped in time, and the grouting can be continued only after the plugging treatment.

3. Stirring of high-strength non-shrinkage grout.

1. Strictly according to the manufacturer's water supply, add 1% water.

2. Use a mechanical mixer to stir, and the mixing time is 5 minutes.

3. The material should be used up within 30 minutes after each stirring.

Fourth, construction. 1. After the grouting starts, the grouting should be carried out continuously to shorten the construction interval as much as possible.

2. The grouting should be grouting from one side until the other side overflows.

5. Maintenance. 1. After the grouting is completed, cover the wet curtain in time and cover it with cotton felt to prevent water loss.

2. Winter grout should be used during winter construction, and stirred with warm water to keep warm and maintained.

The use of grouting is very simple, no matter how much water you add to the grouting material of a good manufacturer, it will come up with strength, and the grouting material is used in order to save worry, of course, it is cheap, and the quality is not good, so it is strictly required to the customer to stir according to the routine, is that scientific? Grouting is so troublesome, it is better to use business mixing, grouting is a product born for everyone to save time and improve efficiency! It's not cement sand, just add some glue powder and mix it!

You can check the Baoye grouting material, you can consult their technology specifically, the grouting process itself is not very complicated, but it is more complicated

Clean the surface of the base layer first and keep it moist.

Secondly, the template is installed, and then an appropriate amount of water and grouting material is added to the mixing drum to stir evenly. Grouting is done from one side until the solution flows out from the other side.

How to use high-strength non-shrinkage grout

In the construction process, high-strength non-shrinkage grout may be used, so how to use high-strength non-shrinkage grout, pay attention to the correct operation. You can take a look at the general method, which has roughly gone through the processes and steps such as foundation cleaning and wetting treatment, formwork support, stirring, and pouring, and pay attention to the correct construction specifications. The coagulation process of grouting material is divided into two stages: initial setting and final setting.

If the high-strength non-shrinkage grout does not condense for more than ten hours, it is necessary to pay attention to the reason. Generally, the initial setting time is two hours, and the final setting time is ten hours. If it does not solidify for a long time, it is necessary to pay attention to whether there is too much moisture or because the temperature is too low and does not solidify.

Pay attention during winter construction.

How to use high-strength non-shrinkage grouting materials

When using high-strength non-shrinkage grouting materials, attention should be paid to the method. 1. The surface of the base should be cleaned up, such as gravel and other debris, so that the base layer is kept moist. Then, it's time to install the template.

In the prepared mixing drum, add the appropriate amount of water and grout material. During the mixing process, the blades cannot be raised to the slurry surface. After stirring well, it can be poured in from one side and the solution flows out from the other side.

After 3 to 5 hours of grouting, the grout surface can be smoothed, covered with a straw bag or damp cloth, and then sanded and watered. The curing time is about 7 days, and the specific number of watering is related to the wetness of the grouting surface. After 24 hours of grouting, the grout can be removed and watered, and after 72 hours, the dying pad can be removed.
