How to apply Sikacryl Grout:
1. Prepare mixers, grouting equipment, molds, and maintenance items. Clear the grouting space and pre-wet the concrete surface beforehand.
2. Set up formwork and seal the connections with cement (sand) mortar and plastic tape to ensure no leakage or slurry渗漏.
3. Add water to the slurry at a rate of 12-15% of its weight and mix (mechanical mixing for 2-3 minutes, manual mixing for over 5 minutes).
4. Pour the well-mixed grout into the grouting area from one direction. Use bamboo sticks or steel rods for guidance if necessary, and gently vibrate or tap the formwork as needed.
5. After construction is completed, cover with a plastic film immediately and then place a thatched curtain or cotton blanket for 3-7 days of moist curing.
6. Operating Temperature.

The strength of Sikal's grouting material is primarily determined by the mix ratio, water-cement ratio, aggregate, admixtures, density, and subsequent maintenance. The mix ratio, through rational mix design, enhances the strength of the grout. The water-cement ratio is directly proportional to the compressive strength of the grout and the strength of the cement used. According to the formula, when the water-cement ratio is equal, grout made with high-strength cement has significantly higher compressive strength than that made with low-strength cement. Additionally, the water-cement ratio is also directly proportional to the strength of the grout. Therefore, it is incorrect to attempt to increase concrete strength by merely increasing cement dosage when the water-cement ratio remains constant; at this point, only the workability, shrinkage, and deformation of the grout can be affected.

Sika Grouting Material Product Features:
Early strength, high strength: compressive strength of 30-50 MPa can be achieved in 1-3 days.
2. High fluidity: Can fill all voids, meeting the requirements for secondary grouting of equipment.
3. Micro-expansive: Ensures tight contact between the equipment and foundation, no shrinkage after secondary grouting. High bonding strength, grip force with round steel not less than 6Mpa.
4. Winter construction feasible: Outdoor work is permitted at temperatures as low as -10°C.
5. High Durability: This product is an inorganic binder material with a service life longer than that of basic concrete. After over one million fatigue tests and 50 freeze-thaw cycles, there is no significant change in strength. The strength is notably improved after soaking in engine oil for 30 days.

High-performance, shrinkage-free grouting material trends
1. Hold the commanding heights of cutting-edge technologies with low-carbon economic characteristics. Information, biology, and nanotechnology are the core technologies of the low-carbon economy, and they are the long-term focus of innovative breakthroughs in high-strength, shrinkage-free grouting materials. They also serve as the technological foundation for enhancing national strength, securing a competitive edge in the future, and developing a low-carbon economy. It is imperative to seize the historical opportunity of China's technology entering a major leap period, achieve original technological breakthroughs in fields such as information, nanomaterials, molecular biology, major diseases, and manufacturing, and create industrial clusters with low-carbon economic features, high-tech industrial clusters, and modern service industrial clusters.
2. Tackle, promote, and普及 urban technologies. The 21st century is China's century of urbanization, and by 2020, the urban population will exceed 900 million. The energy demand and various emissions in cities are tremendous, presenting unprecedented challenges. We must swiftly master applicable technologies in key areas such as urban construction and building materials, comprehensive treatment of urban waste, waste-to-energy power generation, public transportation, and vehicle exhaust emissions. We also need to expedite the establishment of a monitoring system for urban grouting materials.
3. Aggressively implement the national grouting material technology special projects. Carry out technology special projects for common and key technologies in key industries and important regions, major industrialization demonstration projects for significant technical equipment, and technology special projects for high-tech industrialization of the circular economy. Break through the major technical bottleneck of high-strength, shrinkage-free grouting materials, fundamentally change the passive situation where China's grouting material technology is dependent on others, cultivate a batch of environmentally friendly enterprises with independent intellectual property rights, and promote the leapfrog development of the environmental protection industry.
