优砾科 ® B15 属于 UHPFRC 超高性能纤维增强混凝土，专为建筑主体、桥梁、隧道、地下空间、工业储罐等各类混凝土结构加固补强及病害修复研发。产品采用致密颗粒级配堆积体系、超低水胶比搭配特种微细钢纤维增韧复合配方，现场仅添加洁净清水搅拌即可实现自流自密实，支模浇筑后无需振捣作业。UNIKRETE® B15 is an Ultra-High Performance Fibre Reinforced Concrete (UHPFRC), custom-developed for structural strengthening, reinforcement and defect repair of buildings, bridges, tunnels, underground spaces, industrial storage tanks and other concrete structures. Adopting a dense particle packing system, ultra-low water-binder ratio and composite toughening formula with special micro steel fibres, it only requires mixing with clean tap water on site to achieve self-flowing and self-compacting performance without vibration after formwork pouring.
