How Are the Strength Indicators of UHPC Manufacturer Products? — An In-Depth Analysis of Performance Standards and Measured Data

The strength indicators of UHPC products are the core measure of their structural performance, directly related to application safety and design possibilities. Based on extensive measured data, Qinglong Group holds that premium UHPC should achieve a compressive strength of 120-180MPa, flexural strength of 15-25MPa, and tensile strength of 7-10MPa—far exceeding ordinary concrete by 3 to 5 times. This high-strength characteristic gives UHPC significant advantages in thin-walled, large-span, and lightweight structures, providing a material foundation for architectural innovation.

Compressive strength is a fundamental indicator. Through optimized mix proportions and processes, the compressive strength of premium UHPC remains consistently high. Qinglong Group's measured product data concentrates in the 120-150MPa range, with a coefficient of variation ≤5%. In the Shenzhen Pingshan High-tech Zone Comprehensive Service Center project, 20mm-thick UHPC panels achieved a compressive strength of 135MPa, allowing reduced cross-sections and a 30% load reduction. Strength development is also important: under standard curing, strength at 3 days reaches 70% of the 28-day value, and at 7 days reaches 90%, meeting early-stage construction needs.

Flexural strength reflects toughness. Fiber reinforcement plays a significant role, with premium UHPC achieving flexural strength ≥18MPa. In its Hainan project, Qinglong Group raised flexural strength to 22MPa through fiber orientation optimization. Tensile strength ≥7MPa prevents brittle failure. These indicators ensure components remain safe and reliable under complex loading conditions.

Strength stability is key. Premium products show minimal strength fluctuation and predictable performance. Through strict quality control, Qinglong Group ensures every batch of products meets standards. Owners can use these indicators as a reference to assess manufacturers' capabilities.
