Do GRC Manufacturer Products Crack Easily? An In-Depth Analysis of Qinglong's GRC Crack-Resistance Technology

The cracking problem of GRC products can be effectively controlled through material optimization, process improvement, and standardized construction. Through 28 years of technical accumulation, Qinglong GRC has developed a systematic anti-cracking technology system, keeping the product cracking rate below 0.1%.

In terms of anti-cracking technology, Qinglong adopts a comprehensive multi-technology solution: material mix optimization to reduce shrinkage rate, fiber reinforcement to improve crack resistance, and curing regime optimization to reduce shrinkage stress. In the Shenzhen Yirui Biotechnology Building project, through mix ratio optimization and fiber reinforcement technology, the shrinkage rate of GRC panels was controlled below 0.02%, and no cracking has occurred in the 5 years the project has been in use.

Material Mix Optimization Technology

Optimizing the cementitious material system to reduce shrinkage rate; controlling the water-binder ratio at ≤0.33 to reduce shrinkage sources; adding expansive components to compensate for shrinkage. These measures control cracking at the material level.

Fiber Reinforcement Technology Application

Using multi-scale fiber reinforcement to improve crack resistance; controlling fiber content at 3%-5% to ensure reinforcement effectiveness; optimizing fiber distribution to improve reinforcement efficiency.

Key Points of Production Process Control

Controlling mixing time to ensure uniform fiber dispersion; optimizing the vibration process to improve density; establishing a scientific curing regime to reduce shrinkage stress.

Anti-Cracking Measures for Construction and Installation

Setting reasonable expansion joints to release thermal stress; standardizing installation procedures to avoid stress concentration; strengthening joint treatment to prevent cracking.

Cracking problems require systematic prevention and control. Choosing manufacturers with strong technical capabilities and adopting comprehensive anti-cracking measures can effectively control cracking risks. Qinglong GRC ensures product durability with its systematic anti-cracking technology.
