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

The strength performance of UHPC products is the embodiment of their core value. High-quality UHPC can achieve 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 consistently industry-leading strength performance.

In the Shenzhen Yirui Biotech Building project, third-party testing of Qinglong UHPC showed: the 28-day cube compressive strength reached 135MPa, exceeding the standard requirement (100MPa) by 35%; the flexural strength was 22MPa, exceeding the standard requirement (18MPa) by 22%; 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 safe and reliable engineering.

In-Depth Analysis of Compressive Strength Performance

High-quality UHPC maintains a compressive strength above 120MPa, which can reach 150MPa through mix proportion optimization. Strength development is well-balanced, with 3-day strength reaching over 70% of the 28-day strength, meeting rapid construction needs. Qinglong UHPC products maintain compressive strength steadily in the 135-150MPa range.

Flexural Strength Characteristics

Flexural strength is typically 1/6 to 1/8 of compressive strength, with high-quality products reaching 18-25MPa. The flexural toughness index I5≥3.5 exhibits distinct pseudo-strain-hardening characteristics. This toughness ensures ample warning before material 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 allows UHPC to fully leverage its strength advantages in compression members. Qinglong products maintain this ratio steadily at 0.88-0.92.

Strength Stability and Dispersion Control

The strength dispersion coefficient is a key indicator; high-quality 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 high-quality products allows its strength advantages to be fully utilized. With its outstanding strength performance, Qinglong UHPC has become the preferred material for major projects.
