Prestressed ultrahigh-ductility concrete for sleeper and application of prestressed ultrahigh-ductility concrete
The invention provides prestressed ultrahigh-ductility cement for sleepers and application of the prestressed ultrahigh-ductility cement, and relates to the technical field of railway track structures. The prestressed ultrahigh-ductility concrete for the sleeper is composed of powder, cement, a fiber reinforced material, water and auxiliaries. The prestressed ultrahigh-ductility concrete is used as a raw material, and is combined with an integral forming and integral pouring process, so that damages such as surface abrasion, shoulder damage, alkali aggregate reaction and middle cracking of the existing sleeper can be effectively resisted, the overall service life of the sleeper is remarkably prolonged, and the service life of a track structure is prolonged. Meanwhile, the fly ash and the silica fume are made of solid waste recycling materials, and resourceful treatment of solid waste can be achieved.
本发明提供了一种轨枕用预应力超高延性水泥及其应用，涉及铁路轨道结构技术领域。本发明的轨枕用预应力超高延性混凝土由粉料、水泥、纤维增强材料、水、助剂构成。本发明的预应力超高延性混凝土为原料结合一体成型整体浇筑工艺能够有效抵抗现有轨枕表面磨损、肩部损坏、碱骨料反应和轨枕中部开裂等损伤，显著提高轨枕的整体使用寿命，增加轨道结构的使用年限。同时，本发明的粉煤灰和硅灰采用固废回收材料，能够实现固废的资源化处理。
