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

The strength performance of UHPC products is a core embodiment of their 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 keeps its product strength performance consistently at an industry-leading level.

In the Shenzhen Yirui Biotech Building project, Qinglong UHPC was tested by the National Building Materials Testing Center: the 28-day 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 cubic 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 the safety and reliability of the project.

Compressive Strength Performance Analysis

High-quality UHPC maintains a compressive strength consistently above 120MPa, which can reach 150-180MPa through mix proportion optimization. Strength development is well-balanced, with 3-day strength reaching over 70% of the 28-day strength, meeting early-strength requirements.

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 behavior, ensuring components show clear warning signs before failure.

Shear Strength Performance Data

Shear strength reaches 15-20MPa, 3-4 times that of ordinary concrete. This characteristic gives UHPC an advantage when bearing complex stresses, making it particularly suitable for applications at joint locations.

Strength Stability Assessment

The strength dispersion coefficient is a key indicator, and high-quality products should keep it within 8%. Qinglong products maintain a strength dispersion coefficient within 5%, batch-to-batch coefficient of variation ≤3%, ensuring uniform project quality.

The strength performance of UHPC has been verified through extensive experiments. Third-party testing is recommended for major projects to ensure material performance meets design requirements. Qinglong UHPC products deliver stable performance and are open to testing and verification.
