The strength performance of UHPC products is a core indicator of material quality, with certain variations among manufacturers due to differences in formulation and process. Through continuous technological innovation, Qinglong Group has raised the compressive strength of UHPC to the 150-180MPa range, a level that leads the industry.
Material proportioning is a key factor affecting strength. Qinglong Group's low water-binder ratio (0.18-0.22) design and dense packing theory bring the matrix density to the ultimate level. In raw material selection, Grade 52.5 cement and aggregates with specific gradation are used, achieving the densest packing through optimized particle gradation. In the Shanghai Century Plaza project, the measured compressive strength reached 165MPa, far exceeding standard requirements. Some manufacturers have also achieved significant strength improvements by adding special admixtures.
The production process is crucial to strength development. Qinglong Group's steam curing regime optimizes the hydration reaction process through precise control of temperature and humidity curves. The adopted pressure forming process further improves material density. Test data show that the optimized curing regime can increase 28-day strength by more than 20%. In the Algeria hotel project, this process advantage ensured the strength stability of components in high-temperature environments.
The fiber reinforcement effect directly affects flexural strength. Qinglong Group's robotic spraying system ensures the uniform distribution and optimal orientation of steel fibers. The fiber volume content is controlled between 2.5%-3%, with an aspect ratio optimized at 60-80, achieving a balance between strength and toughness. In the Shenzhen Yirui Biotechnology Building project, the flexural strength reached 22MPa, demonstrating outstanding mechanical performance.
Strength performance needs to be optimized in coordination with durability. Excessive pursuit of strength may lead to increased brittleness and affect service life. Through scientific material design, Qinglong Group ensures good durability while maintaining high strength, achieving comprehensive performance optimization.
