引用本文摘 ? 要：在礦物摻合料總摻量35%~60%和水膠比0.42~0.29的情況下，采用粉煤灰、礦粉復摻，設計了系列大摻量礦物摻合料高性能混凝土（HPC）配合比，試驗研究了礦物摻合料摻量、水膠比對HPC坍落度、抗壓強度、抗碳化性能、抗氯離子滲透性能、早期收縮性能的影響。結果表明：礦物摻合料可顯著改善HPC的性能，且隨著水膠比的降低，礦物摻合料對HPC性能的改善效果更顯著；所制備的大摻量礦物摻合料HPC具有良好的技術可行性，滿足相關核電工程設計要求。 Abstract: With total percentage of mineral admixture of 35%~60% and water-binder ratio of 0.42~0.29, the high-performance concrete was made blending with fly ash and slag. The effects of mineral admixture content and water-binder ratio on slump, compressive strength, chloride ion penetration resistance, carbonation resistance, and early shrinkage properties of concrete were studied. The results show that the properties of HPC can be significantly improved by blending with mineral admixture, and with reduction of water-binder ratio, the affection is more significantly. The prepared HPC with large percentage of mineral admixture has good technical feasibility and meets the design requirements of nuclear power projects.
