摘要
评述了超细粉煤灰高强混凝土的综合性能,分析了影响超细粉煤灰高强混凝土的综合性能的主要因素,超细粉煤灰高性能混凝土的早期抗压强度主要取决于水灰比,后期抗压强度主要取决于水胶比和胶凝材料总用量,掺UFA高性能混凝土长期抗压强度增长稳定。同时,耐久性良好,高性能混凝土也具有良好的徐变性能。
The composite properties of ultrafine fly-ash high-strength concrete are reviewed, and predominant factors affecting the composite properties of ultrafine fly-ash high-strength concrete are analyzed. The results show that the early compressive strength is depended on w/c value , the later compressive strength is depended on the w/c value and cement amount, and the long-term strength increases stably. Meanwhile, the UFA high-strength concrete possesses good durability and creep property.
