高性能钢纤维复合材料窨井盖、井座及水篦子,是采用价值工程原理、结合社会需要研制的。并盖结构分为表层和承重层。产品由胶结材料、高强骨料、特细粉和其他材料加入钢纤维组合而成。由于钢纤维的掺人,不仅强化了混凝土界面区的结构性能,提高了混凝土的寿命和承载力,而且可 High-performance steel fiber composite manhole covers, well seats, and rakes are developed using value engineering principles combined with social needs. The cover structure is divided into a surface layer and a load-bearing layer. The product consists of a combination of cementitious materials, high-strength aggregates, ultra-fine powders, and other materials added to steel fibers. Due to the incorporation of steel fibers, not only the structural properties of the interface area of ​​the concrete are enhanced, but also the life and load-bearing capacity of the concrete are improved.
