摘要
以大体积混凝土工程为背景,研究了单掺火山灰、双掺火山灰和磷矿渣二元体系碾压混凝土的抗渗和抗冻耐久性能。工程应用结果表明,掺火山灰碾压混凝土抗渗性能随着混凝土强度等级的提高而提高,各强度等级掺火山灰碾压混凝土抗冻性能均满足工程设计要求,对结构稳定性及工程使用寿命均有良好的效果,可在类似工程中进行推广。
Based on the mass concrete construction, this paper studies on the impermeable performance and the frost resistance durability of RCC mixed with single pozzuolana and mixed with both pozzuolana and phosphorus slag. The results of the engineering application proved that the frost resistance durability becomes better with the increasing strength grade of RCC mixed with pozzuolana. And the frost resistance durability of all strength grade RCC can meet the design requirements of the project, which has good effect on the structural stability and the service life and can be popularized to the similar projects.
