Do GRC Manufacturer Products Crack Easily? Qinglong GRC Manufacturer's Anti-Cracking Technology Research

Cracking is a common issue with GRC products, but it can be effectively prevented through technical means. Qinglong has significantly improved the crack resistance of its products through material optimization and process innovation.

In terms of material formulation, Qinglong uses low-alkali cement and alkali-resistant glass fibers to improve crack resistance at the source. By optimizing the mix proportion, the water-binder ratio is reduced and density is improved. Adding polypropylene fibers forms a secondary reinforcement network that effectively suppresses crack formation. In the curing process, steam curing is employed, with heating and cooling rates controlled to reduce thermal stress.

Design Measures for Crack Prevention

Reasonably configured reinforcing ribs improve crack resistance. Panel dimensions are controlled and appropriate expansion joints are provided.

Key Points for Crack Prevention During Installation

Deformation space is reserved during installation to avoid stress concentration. Flexible materials are used for joint treatment to accommodate deformation.

Usage and Maintenance Recommendations

Conduct regular inspections to promptly detect and address fine cracks. Avoid external impact and maintain normal use.

Through systematic measures, cracking issues can be effectively controlled.
