摘　　要：为解决亚洲基础设施投资开发银行总部工程混凝土高粘度、高水化热等技术难题,需配制性能优越、满足施工要求的C80高抛自密实大体积混凝土,以混凝土拌合物的V漏、倒置与绝热温升为指标,对混凝土粗骨料种类、水胶比、掺合料用量、砂率进行调整与优化,满足工程需求。In order to overcome major technical problems as high viscosity and high hydration heat in key projects of Asian Investment Bank, and prepare C80 high throw from dense bulk concrete, which has superior performance and meets construction requirements, in this paper, the types of concrete coarse aggregate, the ratio of water to glue, the amount of admixture, sand rate are adjusted and optimized, and the targets of V leakage, inversion and adiabatic temperature rise of concrete mixture are taken as the indexes, and the concrete that meets the engineering needs is finally prepared.
