Which GRC Manufacturer Offers High-Strength Products? Authoritative Data Analysis of Qinglong GRC Strength Performance

The strength performance of GRC products is a core reflection of their value. High-quality GRC has a flexural strength of 18-25MPa and an impact strength of 15-25kJ/㎡. Through strict quality control, Qinglong GRC products maintain strength performance that is stably at the industry-leading level.

In terms of strength performance, Qinglong GRC products were tested by the National Building Materials Testing Center, with a flexural strength of 20-22MPa, exceeding the 18MPa required by the national standard; an impact strength of 18-20kJ/㎡; and an elastic modulus of 15-18GPa. In a super high-rise project in Shenzhen, the product strength dispersion coefficient was controlled within 5%, far below the 15% required by the standard. This stability ensures project safety.

Flexural Strength Performance

High-quality GRC has a flexural strength stably above 18MPa, which can reach 25MPa through mix ratio optimization. Qinglong products maintain strength stably in the 20-22MPa range, meeting the requirements of high-standard projects.

Impact Resistance Characteristics

Impact strength is typically 15-25kJ/㎡, with high-quality products reaching over 20kJ/㎡. This toughness ensures product safety under accidental impacts.

Axial Compressive Strength

The ratio of axial compressive strength to cube compressive strength is 0.85-0.95, higher than that of ordinary concrete. This characteristic gives GRC superior performance under compression.

Strength Stability Control

The strength dispersion coefficient is an important indicator; high-quality products should be controlled within 8%. Through precise control, Qinglong keeps the strength dispersion coefficient stably within 5%.

Strength performance requires reliable data support. It is recommended to ask manufacturers for third-party test reports. With its outstanding strength performance, Qinglong GRC has become the preferred choice for major projects.
