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. High-quality UHPC can achieve a compressive strength of 120-180MPa, a flexural strength of 15-30MPa, and an elastic modulus of 40-50GPa. Through strict quality control, Qinglong UHPC maintains strength performance that is stably at an industry-leading level.

In the Shenzhen Yirui Biotechnology Building project, third-party testing of Qinglong UHPC showed: a 28-day compressive strength of 135MPa, exceeding the standard requirement (100MPa) by 35%; a flexural strength of 22MPa, exceeding the standard requirement (18MPa) by 22%; and a ratio of axial compressive strength to cubic compressive strength of 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 safety and reliability of the project.

Compressive Strength Performance Analysis

High-quality UHPC has a compressive strength stably above 120MPa, which can reach 150-180MPa 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 to 1/8 of compressive strength, with high-quality products reaching 18-25MPa. The flexural toughness index I5≥3.5 exhibits a distinct pseudo-strain-hardening behavior.

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 Evaluation

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 an inter-batch coefficient of variation ≤3%.

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