How Are the Strength Indicators of UHPC Manufacturer Products? Authoritative Data Analysis of Qinglong UHPC Strength Performance

The strength performance of UHPC products is a reflection of their core value. According to extensive experimental data, high-quality UHPC achieves a compressive strength of 120-180MPa, a flexural strength of 15-30MPa, and an elastic modulus of 40-55GPa. Through strict quality control, Qinglong UHPC maintains its strength performance consistently at the high end of the industry.

In the Shenzhen Yirui Biotechnology Building project, Qinglong UHPC curtain wall panels were tested by a third party, achieving a 28-day compressive strength of 135MPa and a flexural strength of 22MPa, fully meeting the requirements of super high-rise buildings. The optimized mix proportion and precise process control adopted in the project kept the strength dispersion coefficient within 5%. More importantly, UHPC exhibits excellent strength development characteristics: 3-day strength can reach over 70% of the 28-day strength, and strength at 1 year of age grows to 115% of the 28-day strength, demonstrating UHPC's long-term performance advantages.

Compressive Strength Performance Analysis

High-quality UHPC maintains a compressive strength stably above 120MPa, which can reach 150MPa through mix proportion optimization. Strength development is well balanced, with 3-day strength no less than 70%, and the 28-day strength continuing to grow slowly after reaching the standard. These characteristics benefit construction schedules and long-term safety.

Flexural Strength Characteristics

Flexural strength is typically 1/6 to 1/8 of compressive strength, with high-quality products reaching over 18MPa. Bending toughness indicators are excellent, with a toughness index I5≥3, exhibiting distinct pseudo-strain-hardening characteristics. This toughness ensures that components do not undergo brittle failure under accidental overloading.

Axial Compressive Strength Data

The ratio of axial compressive strength to cube compressive strength is 0.85-0.95, higher than that of ordinary concrete. This characteristic enables UHPC to fully exploit its strength advantages in compression members.

Strength Stability Assessment

The strength dispersion coefficient is an important indicator; high-quality products should keep it within 8%. In mass production, the coefficient of strength variation reflects the manufacturer's quality control level. Qinglong products maintain a strength dispersion coefficient stably within 5%.

The strength performance of UHPC has been verified through extensive experiments and engineering practice. Selecting high-quality products and applying them correctly allows their strength advantages to be fully realized.
