Ultra-high-performance anti-impact anti-abrasion concrete
The invention relates to ultra-high-performance anti-impact anti-abrasion concrete. Cement, microbeads and silica fume are used as cementing materials; aggregate and ultrafine aggregate are added to perfect the grain composition; nanometer ultrafine silicon dioxide, fibers, a water reducing agent, a defoaming agent, a regulating agent, a coagulation accelerator and a retarder are added to be usedas functional auxiliary agents. The concrete can be used for building or repairing parts with impact abrasion damage in hydraulic structures, can also be used for engineering parts with structure impact damage needing to be repaired, and has good construction performance, mechanical performance and impact abrasion resistance.
本发明涉及一种超高性能抗冲磨混凝土，以水泥、微珠、硅灰为胶凝材料，添加骨料和超细骨料完善颗粒级配，并添加纳米超细二氧化硅、纤维、减水剂、消泡剂、调节剂、促凝剂和缓凝剂作为功能助剂，可对水工建筑中具有冲磨破坏的部位进行修建或修复，亦可使用在具有结构冲击破坏需进行修复的工程部位，拥有良好的施工性能、力学性能和抗冲磨性能。
