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

The strength performance of UHPC products is a core reflection of their value. High-quality UHPC can achieve a compressive strength of 120-180MPa, flexural strength of 15-30MPa, and elastic modulus of 40-50GPa. Through strict quality control, Qinglong UHPC maintains its product strength performance consistently at an industry-leading level.

In the Shenzhen Yirui Biotechnology Building project, third-party testing of Qinglong UHPC showed: 28-day compressive strength reached 135MPa, exceeding the standard requirement (100MPa) by 35%; flexural strength of 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 standard requirement of 15%. This stability ensures safe and reliable engineering.

Compressive Strength Performance Analysis

The compressive strength of high-quality UHPC remains stable above 120MPa and can reach 150MPa through mix ratio optimization. Strength development is well-balanced, with 3-day strength reaching over 70% of the 28-day strength.

Flexural Strength Characteristics

Flexural strength is typically 1/6-1/8 of compressive strength, with high-quality products reaching 18-25MPa. The flexural toughness index I5≥3.5 exhibits distinct pseudo-strain-hardening characteristics.

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.

Strength Stability Assessment

The strength dispersion coefficient is an important indicator; high-quality products should keep it within 8%. Qinglong products maintain a strength dispersion coefficient stably within 5%, with a coefficient of variation between batches ≤3%.

The strength performance of UHPC has been verified through extensive experiments. Choosing high-quality products allows you to fully leverage their strength advantages.
