  • Detail

The development of cement high-strength non shrinkage grouting material technology has played a great role in the development of reinforcement and reconstruction. In recent years, the strength of grouting materials has been improving, which reflects the continuous improvement of the grouting material industry and promotes the development of reinforcement and reconstruction

what are the characteristics of high-strength non shrinkage grouting materials? Today, the road and Bridge editor summarized the following eight characteristics:

1. Early strength and high strength of high-strength non shrinkage grouting material: 1-3 days compressive strength of more than 30-50mpa

2. Anti segregation performance of high-strength non shrinkage grouting material: high-strength non shrinkage grouting material overcomes the segregation phenomenon caused by excessive water addition in field use

3. High strength non shrink grouting material is green and environmental friendly: it does not contain benzene homologues, halogenated hydrocarbons, formaldehyde, heavy metals and other components. It is non-toxic, tasteless, pollution-free, non combustible and non explosive, and can be transported as general goods

4. Micro expansibility of high-strength non shrinkage grouting material: ensure close contact between the equipment and the foundation, and no shrinkage after secondary grouting

5. High strength non shrinkage grouting material has high self fluidity: it can fill all gaps and meet the requirements of secondary grouting of equipment

6. High strength non shrinkage grouting material can be constructed in winter: outdoor construction is allowed at -10 ℃

7. High strength non shrinkage grouting material has strong durability: after millions of fatigue tests and 50 freeze-thaw cycles, the strength has no obvious change. After soaking in engine oil for 30 days, the strength is significantly improved

8. Crack resistance of high-strength non shrinkage grouting material: cracks due to uncertain water addition, uncertain ambient temperature and limited maintenance conditions during field use
