摘要
海洋环境中混凝土耐久性和抗压强度是结构设计需要考虑的两个重要方面。通过试验研究了耐久混凝土抗压强度的变化规律,基于试验结果,定量分析了龄期、水胶比、粉煤灰掺量、骨料级配、最大骨料直径和掺耐蚀剂对耐久混凝土抗压强度的影响,获得了一些结论,为海洋环境钢筋混凝土结构耐久性设计提供理论依据。
The durability and compressive strength of concrete located in a costal environment are two important aspects that need to be considered in the design of structures.The variation characteristics of the compressive strength of durable concrete are studied by experiment.Based on the experimental results,the effects of the curing age,water/binder ratio, fly ash content, aggregate gradation,maximum aggregate diameter, and addition of anti-corrosion proclucts on the compressive strength of durable concrete are evaluated in a quantitative manner.Some useful conclusions are drawn, which can provide theoretical evidence for the durability design of steel reinforced concrete structures located in a costal environment.
