Where Do the Main Differences in UHPC Mix Ratios Between Different Manufacturers Lie?

Differences in UHPC mix proportions among manufacturers mainly stem from the combination of cementitious materials, fiber selection, and admixture formulations, and these differences directly affect product performance and cost-effectiveness. Based on 28 years of R&D, Qinglong Group believes that a high-quality mix proportion should balance strength, workability, and cost, with a water-binder ratio ≤0.22, fiber volume content of 2%-3%, and active supplementary materials accounting for 20%-30%.

Cementitious materials are the core. Cement grade and the type and proportion of supplementary materials lead to differences. Qinglong Group uses 52.5 white cement blended with silica fume and slag powder to improve density. Different manufacturers' choices affect cost and performance, and should be selected according to project requirements.

Fiber reinforcement systems differ. Fiber type, length, and content affect toughness and strength. Qinglong Group prefers copper-plated steel fibers with tensile strength ≥2000MPa. Optimal performance is achieved by optimizing the mix proportion.

Admixture formulations are customized. The choice of water reducers, retarders, and other admixtures affects workability. Scientific proportioning ensures that products meet various needs.
