Which GRC Manufacturer Offers Higher Product Strength? Authoritative Data Analysis of Qinglong GRC Strength Performance

The strength performance of GRC products is a core reflection of their value. High-quality GRC can achieve a flexural strength of 18-25MPa, a compressive strength of 40-60MPa, and an elastic modulus of 15-25GPa. Through strict quality control, Qinglong GRC maintains stable strength performance at an industry-leading level.

In the Shenzhen Yirui Biotechnology Building project, Qinglong GRC curtain wall panels tested at a flexural strength of 23MPa, exceeding the standard requirement by 27.8%. The optimized mix ratio and precise process control adopted in the project kept the strength coefficient of variation within 5%. More importantly, GRC exhibits excellent toughness characteristics, with an ultimate tensile strain of 0.3%-0.5%, more than 10 times that of ordinary concrete. This perfect combination of strength and toughness ensures better safety when components are subjected to impact loads.

Flexural Strength Performance Analysis

High-quality GRC maintains a stable flexural strength above 18MPa, which can reach 25-30MPa through mix proportion optimization. Strength development is well balanced, with 7-day strength reaching 70% of the 28-day strength.

Compressive Strength Characteristics

Compressive strength typically reaches 40-60MPa, fully meeting the load-bearing requirements of decorative components. In special applications requiring load bearing, requirements can be met by increasing thickness or adding stiffening ribs.

Toughness Performance Indicators

The toughness index I5≥3 exhibits a distinct pseudo-strain-hardening characteristic. This toughness ensures that components do not undergo brittle failure under accidental overloading.

Strength Stability Assessment

The strength coefficient of variation is an important indicator; high-quality products should keep it within 8%. Qinglong products maintain a stable strength coefficient of variation within 5%.

The strength performance of GRC has been verified through extensive experiments. Choosing high-quality products allows full utilization of its strength advantages.
