Which GRC Manufacturer Offers High-Strength Products? — Qinglong GRC's Strength Technology Advantages

The strength performance of GRC products depends on three major factors: material mix ratio, fiber reinforcement, and production process. Quality products should have a compressive strength of 40-60MPa, a flexural strength of 15-25MPa, and a tensile strength of 7-10MPa. Through four key technologies—low water-cement ratio (0.30-0.35), high-efficiency water reducer (water reduction rate ≥25%), optimized fibers (volume fraction 4%-5%), and autoclave curing (0.8-1.0MPa)—Qinglong GRC achieves a flexural strength of 20-25MPa, 30%-50% higher than ordinary GRC.

Strength assurance: carefully selected raw materials with cement strength grade ≥42.5; premium fibers with tensile strength ≥1700MPa; precise mix ratio with error ≤0.5%; scientific curing ensuring full strength development. Comparative tests by a testing institution show that the strength dispersion coefficient of Qinglong GRC is ≤5%, far below the industry average of 15%.

Flexural Strength Advantages

The standard requires ≥18MPa, while Qinglong GRC reaches 20-25MPa; fibers are evenly distributed for high reinforcement efficiency; strong interfacial bond strength ensures effective stress transfer; the failure mode is multiple cracking, providing good safety. Flexural strength is a key indicator.

Compressive Strength Performance

Compressive strength of 40-60MPa, comparable to concrete; high density with porosity ≤8%; stable strength development, meeting standards at 28 days; long-term strength continues to grow. Compressive strength meets load-bearing requirements.

Tensile Strength Characteristics

Direct tensile strength of 7-10MPa, 8-10 times that of ordinary concrete; ultimate tensile strain of 0.02%-0.03% with pronounced pseudo-ductility; strong crack control capability with crack width ≤0.1mm. Tensile performance mitigates brittleness.

Elastic Performance Indicators

Elastic modulus of 20-25GPa with moderate stiffness; good linearity in the stress-strain relationship; deformation capacity superior to ordinary concrete; modulus well matched with steel reinforcement. Elastic performance suits composite structures.

Strength performance is the guarantee of safety. Qinglong GRC leads in technology, with safe and reliable products.
