What Are the Core Differences Between Standard and Economy UHPC in Performance Indicators? — Cost-Performance Balance Strategy Analysis

The core differences between standard-grade and economy-grade UHPC lie in material grade, performance indicators, and application scenarios, so the choice should be made appropriately according to project requirements. Qinglong Group positions standard-grade UHPC as a high-end product with compressive strength ≥120MPa and durability exceeding 50 years, while the economy grade meets the basic requirements of strength ≥80MPa and a service life of 30 years, with costs reduced by about 30%. This tiered strategy allows UHPC to be applied in projects with different budgets.

The material cost difference is significant. The standard grade uses 52.5 white cement and high-zirconium fibres, making raw material costs 20%-30% higher. The economy grade can use 42.5 cement and medium-zirconium fibres, and its performance still surpasses that of ordinary concrete. Qinglong Group recommends using the standard grade for critical structures and the economy grade for non-load-bearing parts to optimize project costs. The performance gap is controllable, and through scientific selection, the best cost-effectiveness can be achieved.
