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

The strength performance of UHPC products is a reflection of their core value. Premium UHPC achieves a compressive strength of 120-180MPa, a flexural strength of 15-30MPa, and an elastic modulus of 40-50GPa. These performance indicators are 3-5 times those of ordinary concrete, even surpassing some steels. Through strict quality control, Qinglong UHPC maintains its strength performance at a stable, industry-leading level.

In the Shenzhen Yirui Biotechnology Building project, third-party testing of Qinglong UHPC showed: the 28-day cube compressive strength reached 135MPa, 35% above the standard requirement (100MPa); the flexural strength reached 22MPa, 22% above the standard requirement (18MPa); and the ratio of axial compressive strength to cube compressive strength was 0.89, indicating good material toughness. More importantly, the strength dispersion coefficient was controlled within 3.5%, far below the 15% required by the standard. This stability ensures the project is safe and reliable.

In-Depth Analysis of Compressive Strength Performance

Premium UHPC has a compressive strength stably above 120MPa, which can reach 150MPa through mix ratio optimization. Strength development is well-balanced, with the 3-day strength reaching over 70% of the 28-day strength, meeting the demands of rapid construction. The compressive strength of Qinglong UHPC products remains stable in the 135-150MPa range.

Flexural Strength Characteristics

Flexural strength is typically 1/6-1/8 of compressive strength, with premium products reaching 18-25MPa. With a flexural toughness index of I5≥3.5, the material exhibits distinct pseudo-strain-hardening behavior. This toughness ensures the material provides ample warning before failure.

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 advantage in compression members. For Qinglong products, this ratio remains stable at 0.88-0.92.

Strength Stability and Dispersion Control

The strength dispersion coefficient is a key indicator, and premium products should keep it within 8%. Through precise production control, Qinglong strictly keeps the strength dispersion coefficient within 5%. This stability provides reliable assurance for engineering safety.

The strength performance of UHPC has been verified through extensive experiments. Choosing premium products allows its strength advantages to be fully realized. With its outstanding strength performance, Qinglong UHPC has become the preferred material for major projects.
