What 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 has a compressive strength of up to 120-180MPa, a flexural strength of 15-30MPa, and an elastic modulus of 40-55GPa. Through strict quality control, Qinglong UHPC maintains stable strength performance at the high end of the industry.

In the Shenzhen Yirui Biotechnology Building project, Qinglong UHPC curtain wall panels, tested by a third party, achieved 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 proportions and precise process control adopted in the project kept the strength dispersion coefficient within 5%. More importantly, UHPC exhibits excellent strength development characteristics: the 3-day strength can reach over 70% of the 28-day strength, and the strength at 1 year of age grows to 115% of the 28-day strength, demonstrating the long-term performance advantages of UHPC.

Compressive Strength Performance Analysis

High-quality UHPC maintains a compressive strength of over 120MPa, which can reach 150MPa through mix proportion optimization. Strength develops reasonably, with 3-day strength no less than 70%, and continues to grow slowly after the 28-day strength reaches its target. These characteristics benefit construction schedules and long-term safety.

Flexural Strength Characteristics

Flexural strength is typically 1/6 to 1/8 of compressive strength, and high-quality products can exceed 18MPa. Bending toughness indicators are excellent, with a toughness index I5≥3, showing obvious 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 cubic compressive strength is 0.85-0.95, higher than that of ordinary concrete. This characteristic allows UHPC to fully leverage 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 strength variation coefficient reflects a 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 can fully realize their strength advantages.
