摘要
结合安徽界阜蚌高速公路阜蒙新河特大桥工程 ,研究C5 0高性能粉煤灰混凝土制备、拌和物性能、力学性能和长期耐久性。在混凝土中掺入一定量的Ⅰ级粉煤灰 ,不但能改善混凝土的工作性 ,提高混凝土力学性能 。
Through the Fu-men Xinhe extra-large bridge engineering of Jie-Fu-Bang expressway in Anhui province,the mix design,the workability of mixture,the mechanical performance and the long durability of C50 high-performance concrete with fly ash was studied By mixing some amount of grade I fly ash into concrete,not only the workability and mechanical performance,but also the durability of concrete was improved greatly
