Preparation
Before grouting, the surface of the base material in contact with the grouting material should be cleaned and roughened. The surface of the base concrete should be fully moistened 24 hours before grouting, and the accumulated water should be removed 1 hour before grouting.
Grouting material preparation
1. When mixing cement-based grouting materials, add water according to the water content specified in the product qualification certificate. Weigh the water first, then pour the grouting material into the water and stir.
2. Before grouting, select (but not limited to) the following equipment and instruments according to the characteristics of on-site grouting: mechanical stirring; forced concrete mixer; manual stirring; hand-held drill stirrer. The mixing time is 3-5 minutes, and the mixing location should be close to the grouting material location. If there are a lot of bubbles on the surface, let it stand for 3 minutes before pouring, or you can tap the formwork appropriately.
3. Grouting should be continuous, and the mixed grouting material should be used up within 30 minutes.
4. Vibration is strictly prohibited during grouting. Appropriate insertion and tapping on the formwork are allowed.
Curing of grouting material
1. After grouting, the exposed parts should be sprayed with curing agent or covered with plastic film in time, and covered with wet straw bags to keep them moist.
2. When using plastic film covering, the exposed surface of the grouting material should be covered tightly to keep the condensation water inside the plastic film.
3. If the surface of the grouting material is inconvenient to water, a curing agent can be sprayed.
4. The watering curing time should be no less than 7 days, and the number of watering times should keep the grouting material moist.
Precautions
1. According to the weather forecast. Avoid outdoor construction on rainy days. If the working surface is rained on during the process, a rain cloth should be set up immediately. If rainwater is poured in, rework is required.
2. The standard water content of this product is 0.12-0.14. The water-cement ratio is an important part of cement grouting material, and arbitrary addition of water will affect the product performance of cement grouting material.
3. Use special mechanical forced rapid mixing for 3-4 minutes to prevent uneven mixing and the inclusion of unmixed materials, which will affect the later strength of the cement grouting material. Do not use manual ground shovel mixing.
4. Pay attention to temperature changes before construction. Temperature affects the initial and final setting time and fluidity of the cement grout. The recommended construction temperature is 5-35℃. For low-temperature construction below zero, please inform our company in advance. We have corresponding high-early-strength and freeze-thaw resistant products.
5. Mechanical vibration is strictly prohibited during construction; however, channeling is allowed. Prevent stratification and bleeding of the cement grout.
6. The dry density of the cement grout is 2400KG/m³. Calculate the required amount based on the cubic meter of the project. Mix only the amount needed! Strictly prohibit mixing a large amount that will not be used to avoid waste. Leftover material is strictly prohibited from being remixed with the grout for reuse.
7. Strictly prohibit the arbitrary addition of any chemical substances on-site to alter the product performance of the cement grout.
8. This product must be protected from moisture or rain. It can only be reused after passing the quality inspection after the expiration date.
