汾河二库常态混凝土配合比优化设计

Optimum Design on Normal Concrete Mix of Fenhe Reservoir Ⅱ

通过对水泥、粉煤灰及砂石骨料原材料进行性能试验 ,并对四种粉煤灰、五种外加剂进行优选 ,经过大量混凝土性能试验 ,确定合理的混凝土配合比参数 。

In this paper, four kind kinds of fly ash and five kinds of admixture are selected through the performance test on the raw material such as the cement, fly ash and aggregate, the rational normal concrete mix parameters are also determined through the performances test on the normal concrete, finally, the concrete mix to meet the requirement of the design for Fenhe Reservoir Ⅱ is chosen.
