Ultra-high performance concrete for light bridge deck slab and preparation method of ultra-high performance concrete
The invention relates to the technical field of cement-based building materials, in particular to ultra-high performance concrete for a light bridge deck and a preparation method thereof.Portland cement and aluminoferrite cement are adopted as composite cement, active metakaolin powder, superfine fly ash and silica fume are added as composite admixtures, and self-repairing aggregate and POM fiber are matched to prepare the ultra-high performance concrete for the light bridge deck. The self-made polycarboxylic acid water reducer is added to control the construction performance of the concrete, and the composite expanding agent is added, so that the ultra-high performance concrete with low volume weight, high strength and low shrinkage for the light bridge deck is prepared.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一轻质桥面板用超高性能混凝土及其制备方法，本发明采用硅酸盐水泥和铁铝酸盐水泥作为复合水泥，添加活性偏高岭土粉、超细粉煤灰、微硅粉作为复合掺合料，并配合自修复集料和POM纤维，添加自制聚羧酸减水剂控制混凝土施工性能，并添加复合膨胀剂，制备得到具有低容重、高强度、低收缩的轻质桥面板用超高性能混凝土。
