C50海工清水混凝土配制技术研究

Research on Preparation Technology of C50 Fair-faced Concrete

针对C50海工清水混凝土设计要求,以抗裂性、耐久性为主要设计目标,采用粉煤灰+矿粉大掺量矿物掺合料的胶凝材料体系配制C50海工清水混凝土,通过试验配制出耐久性满足要求,具有良好抗裂性能的低收缩C50海工混凝土,达到清水混凝土的技术要求。

In accordance with the design requirements for C50 fair-faced concrete,the C50 fair-faced concrete was formulated with a cementitious material system that a large amount of fly ash and mineral admixture,for the main objective of crack resistance and durability.The test of C50 marine concrete was formulated to meet the requirements of durability,and had a good crack resistance performance to meet the technical requirements of fair-faced concrete.
