The grouting material is made of high-strength materials as aggregates, Portland cement or ordinary Portland cement as the binding agent, and imported additives and other substances. It is very convenient to use, just add water on site and stir evenly before use.
The methods of using grouting materials are similar. Correct use will produce the best results.
1. Amount of water added. For secondary filling in small spaces, water can be added directly to mix into a slurry. Standard model The amount of water added is 13-15% of the grouting material. For the addition of aggregates, for the filling of large-space concrete cavities, stones with a particle size of 5 to 10 mm can be added in a ratio of stone:ugm=0.3:1 (can be changed according to needs in special circumstances), and the amount of water added is 20% of the grouting material.
2. Watering method, continuous grouting without interruption and shortening the grouting time as much as possible. Vibration is strictly prohibited during the grouting process. If necessary, bamboo chips can be used to guide the flow. After the filling is dense and slightly dry, the outer surface is smoothed and calendered.
3. Before construction, the floating soil and loose objects in the filling space should be cleaned up, oil stains should be removed, and the surface of the filling space should be cleaned Concrete needs to be pre-wetted with clean water for 6 to 12 hours.
Widely used in high-speed railways, metallurgy, petrochemicals, electric power, coal, machinery, construction, light industry, marine It is used in major national engineering projects such as equipment installation, structural reinforcement, and building maintenance in the fields of engineering, roads and bridges, environmental protection, and municipal administration. </p
