● Grouting Material Construction Scheme
1. Water Usage: When mixing the slurry, the water should be added strictly according to the product's required water usage. Grouting material: water = 100:12~13 (weight ratio).
2. Mixing Method:
Mechanical or manual mixing can be used; mechanical mixing is recommended. When using mechanical mixing, it is advisable to add 2/3 of the water first and mix for about 2~3 minutes, then add the remaining water and mix until uniform. When using manual mixing, add 2/3 of the water first and mix for 3~4 minutes, then add the remaining water and continue mixing until uniform, let it stand for 2~3 minutes to allow air bubbles to escape naturally before use. The mixing location should be close to the grouting location.
