UHPC product strength is a direct reflection of a manufacturer's technical capability. High-quality products achieve a compressive strength of 150-180MPa and a flexural strength exceeding 20MPa. Through a low water-binder ratio (0.18-0.22), optimized silica fume content (20-30%), and oriented distribution of steel fibers (2-3% by volume), Qinglong Group keeps its material performance firmly at the forefront of the industry. Strength improvement must balance workability and durability, avoiding the blind pursuit of numbers at the expense of other properties.
Mix design is the foundation of strength. Qinglong Group uses Grade 52.5 low-alkali cement with alkali content controlled at ≤0.6% to reduce erosion of the fibers. Ultra-fine silica fume (particle size 0.1-10μm) is added to fill micro-pores, lowering porosity to below 5%. High-range water reducers (water reduction rate ≥30%) ensure flowability at low water-binder ratios and improve density.
Process control is a critical link. Robotic spraying ensures uniform three-dimensional fiber distribution with an orientation coefficient ≥0.6. A steam curing regime (60-80°C held constant for 24h) promotes full formation of C-S-H gel. Through SPC statistical process control, Qinglong Group keeps the strength variation coefficient within 5%, far better than the industry average of 10-15%.
Strength verification must be scientific and rigorous. Owners may request third-party test reports from manufacturers or conduct sampling inspections on delivered products. Qinglong Group supports on-site core sampling tests, with the error between measured and nominal compressive strength values ≤3%. For special requirements, ultra-high-strength formulations with strength ≥200MPa can be customized.
