摘要
针对目前我国再生混凝土使用的局限,着眼于经济、环保的可持续性发展,从滨海环境混凝土材料面临的主要腐蚀特点出发,研究再生骨料混凝土满足标准工作性能的抗腐蚀能力.结果表明：采用粉煤灰掺合料和特定外加剂改性后,C30～C40再生混凝土强度及耐久性均符合规范对普通混凝土的基本要求,具有良好的使用前景,为拓宽再生混凝土利用领域提供了参考.
This research is carried out under the instruction of pump concrete, mixing with recycled coarse aggregate, to get a conclusion from the durability test against the port corrosion environment. The experiment shows that it is possible to improve the durability of C30- C40 concrete after cement is partly replaced by fly-ash and mixed with specified admixture, so as to fulfill the basic requirement of commercial concrete. It could bring a reasonable orientation to use recycled aggregate concrete for civil structure in port environment, and to provide conditions for the sustainable development of economy and environment.
