High-strength non-shrink grouting material

Grouting material is a kind of professional building material carefully formulated with high-strength aggregates, special cement as binders, and various functional substances such as high fluidity, micro-expansion, and anti-segregation. At the construction site, it can be put into use after adding an appropriate amount of water in proportion and stirring evenly, with simple operation.

It has excellent performance advantages. Firstly, it has early strength and high strength. The early strength grows rapidly, and the compressive strength can reach ≥20MPa in 1 day and ≥30MPa in 3 days, which can meet the needs of emergency construction and rapid loading. When it reaches the 28-day age, the compressive strength can be as high as ≥75MPa, providing long-term and stable support for the project. Secondly, it has high fluidity. It has excellent self-leveling performance, and can easily fill various complex and narrow gaps and corners by virtue of its own fluidity without vibration, ensuring seamless connection between the equipment foundation and the grouting material, and greatly improving the construction efficiency. In addition, it has micro-expansion characteristics. After grouting, the material will produce micro-expansion, which can effectively offset the shrinkage caused by the cement hardening process, ensure the close fit between the equipment and the foundation, and avoid problems such as cracks and loosening, thus enhancing the integrity and stability of the structure.

This grouting material is widely used in various engineering scenarios. It is widely used in the anchoring of anchor bolts and machine bases of various large-scale equipment and precision equipment, as well as the connection and pouring between steel structures (such as steel rails, steel frames, steel columns, etc.) and foundations, which can ensure the stable installation and smooth operation of the equipment. It is also suitable for the reinforcement of beams, slabs, columns, foundations and other parts of buildings, which can effectively improve the bearing capacity and seismic performance of the building structure. Moreover, it can be used for the rapid repair of cement concrete pavements and airport runways. With its early strength and high strength characteristics, the strength can reach 15MPa in 2 hours, which can quickly restore traffic.

In short, grouting material, with its excellent performance, wide application range and relatively simple construction technology, has become an ideal choice for many construction projects, equipment installation and reinforcement projects, providing a solid guarantee for the quality and safety of various projects.
