Compressive Strength Standards and Influencing Factors of 30mm Thick UHPC Panels

The compressive strength of 30mm thick UHPC panels is the core indicator for measuring their structural performance, and premium products should reach 100-150MPa. Through optimized mix ratios and processes, Qinglong Group keeps the compressive strength of 30mm panels stable at above 120MPa, with the coefficient of variation controlled within 5%.

Material mix ratio is the foundation of strength. The water-binder ratio is controlled at 0.20-0.22, with silica fume and slag powder added to improve density. A fiber volume content of 2%-3% ensures toughness. Qinglong Group adopts a standard curing regime, achieving a 100% compliance rate for 28-day strength.

Production processes guarantee strength development. High-pressure molding and steam curing optimize the microstructure. Thickness uniformity affects strength, with deviations controlled within ±1.5mm. Through full-process monitoring, stable performance is ensured for every panel.
