What Are the Key Points of the Production Process for High-Strength GRC Panels? The Core of High-Strength GRC Technology

The production process of high-strength GRC panels (flexural strength ≥20MPa) hinges on four key aspects: low water-binder ratio (0.30-0.33), high-efficiency water reducer (water reduction rate ≥25%), optimized admixtures (silica fume 8%-10%), and autoclave curing (0.8-1.0MPa, 180-200℃). Strict control of these points achieves strength more than 50% higher than ordinary GRC.

Production process flow: batching accuracy error ≤1% → mixing time 3-5min → forming vibration frequency 50Hz → autoclave curing 8-10h. For a project with high-strength requirements, the measured compressive strength of the products reached 45MPa, flexural strength 22MPa, and elastic modulus ≥20GPa. Through strict process control, Qinglong GRC high-strength panels achieve a strength dispersion coefficient ≤5%.

Mix Proportion Design Essentials

Water-binder ratio 0.30-0.33; silica fume content 8%-10%; these key points determine the foundation of strength.

Mixing Process Control

Accurate feeding sequence; sufficient mixing time; these controls ensure uniformity.

Forming Process Essentials

Vibration frequency 50Hz; appropriate vibration time; these key points ensure compactness.

Curing Regime Optimization

Autoclave curing 0.8-1.0MPa; these optimizations promote strength development.

High strength requires refined processes. Qinglong GRC maintains strict control for stable quality.
