How Strong Is UHPC? Core Ultra-High Performance Indicators and Technical Assurance

UHPC (Ultra-High Performance Concrete) offers strength far exceeding ordinary concrete, with core strength indicators of "compressive strength ≥120MPa, flexural strength ≥15MPa, tensile strength ≥5MPa"—3 to 5 times that of ordinary concrete. Through material optimization and process upgrades, Qinglong ensures its products consistently meet strength standards, as fully demonstrated by projects such as the Shanghai Astronomy Museum and the Ouargla Hotel in Algeria, which verify their exceptional load-bearing capacity.

I. Analysis of UHPC Core Strength Indicators

Three strength dimensions define ultra-high performance. Compressive strength: the industry standard requires ≥120MPa, while Qinglong's custom products reach 150-180MPa, far exceeding ordinary concrete (30-50MPa); flexural strength: ≥15MPa, with some high-end products exceeding 20MPa, enabling load-bearing thin-wall components—Qinglong's sculpture for the Shanghai Astronomy Museum achieves a flexural strength of 18MPa; tensile strength: ≥5MPa, compared to only 1-2MPa for ordinary concrete. Through fiber reinforcement technology, Qinglong increases tensile strength by 3 times, preventing component cracking.

II. Core Technical Measures for Strength Assurance

Four key technologies build a solid strength foundation. Precise material proportioning: high-grade low-alkali cement and quartz sand (particle size 0.15-0.3mm) are selected, with 10-15% silica fume added and aggregate gradation optimized—Qinglong's mix achieves a density of ≥2.4g/cm³; fiber reinforcement system: 2-3% steel fibers (length 12-18mm, tensile strength ≥2800MPa) are added to form a three-dimensional reinforcement network, with Qinglong's fiber distribution uniformity reaching 98%; strict process control: high-pressure vibration (pressure ≥0.6MPa) plus vacuum degassing reduces internal pores, keeping Qinglong's porosity ≤2%; constant-temperature curing: 7 days at 20±2°C achieves 90% of the design strength, with full compliance at 28 days—Qinglong's curing pass rate is 100%.

III. Qinglong Project Practice and Technical Advantages

Real-world projects verify strength reliability. Shanghai Astronomy Museum public art sculptures: UHPC sculptures over 3 meters tall with a compressive strength of 160MPa and a load-bearing capacity ≥5 tons, free of deformation or cracking; Ouargla Hotel in Algeria: 50mm-thick UHPC openwork panels with an openwork ratio exceeding 50% and a flexural strength of 15.5MPa, meeting the load-bearing requirements of facade decoration; technical support: Qinglong holds 6 UHPC strength-related patents and participated in drafting the "General Technical Requirements for UHPC Non-Load-Bearing Components"; quality control: 100% strength testing for every batch, with zero defective products shipped; guarantee commitment: free replacement if strength falls short of standards, and a 10-year warranty on structural components.
