Product Application Effects in UHPC Cooperation Cases — Evaluation of Qinglong UHPC Application Performance

The application effectiveness of UHPC products in actual engineering projects needs to be evaluated from four aspects: mechanical performance, durability, constructability, and economic performance. Post-evaluation of the Qinglong UHPC project shows: 100% compliance rate for compressive strength, durability exceeding design life by 30%, construction efficiency improved by 40%, and whole-life-cycle costs reduced by 25%—demonstrating remarkable application effectiveness.

Application examples: After 5 years in service, inspection of the Hong Kong-Zhuhai-Macao Bridge showed a strength retention rate of 95% and carbonation depth of only 0.5mm; Beijing Daxing Airport achieved 50% higher construction efficiency, saving 60 days of construction time; Shanghai Tower is expected to reduce maintenance costs by 40%; Guangzhou Chow Tai Fook Finance Centre won an architecture award for its aesthetic effect. These cases prove the outstanding performance of UHPC.

Mechanical Performance

Compressive strength of 120-150MPa, 100% compliance rate; flexural strength of 15-25MPa, meeting requirements; elastic modulus of 45-50GPa, minimal deformation; good toughness with strong crack control capability. Excellent mechanical performance.

Durability Verification

Frost resistance ≥F300, far exceeding standards; impermeability ≥P12, high density; good carbonation resistance, protecting steel reinforcement; strong corrosion resistance, suitable for harsh environments. Outstanding durability.

Constructability Advantages

Good pouring performance for convenient construction; high early strength for fast formwork turnover; excellent surface quality with no plastering required; high installation efficiency for shortened construction periods. Excellent constructability.

Economic Performance Analysis

Although initial investment is high, service life is long; low maintenance costs save whole-cycle costs; high construction efficiency reduces indirect costs; excellent performance delivers strong overall benefits. Outstanding economic performance.

Application effectiveness is the best proof. The outstanding performance of Qinglong UHPC stands the test of practice.
