摘　　要：对高贝利特水泥 (highbelitecement ,HBC)低热高抗裂大坝混凝土的性能进行了研究 ,并通过与三峡二期大坝中热水泥 (moderateheatcement,MHC)混凝土的平行对比实验 ,论证了HBC大坝混凝土具有良好的工作性、力学性能和耐久性能。在相同配合比下 ,HBC大坝混凝土的绝热温升将降低 3～ 5℃。抗裂性分析表明HBC大坝混凝土具有良好的抗裂能力。HBC大坝混凝土是一种可望在水工大体积混凝土工程中推广应用的低热高抗裂大坝混凝土。High Belite cement (HBC) dam concrete with low-heat and high crack resistance was investigated. Compared with the moderate heat cement (MHC) concrete used for Three Gorges Dam in the second stage, the HBC dam concrete has a good working performance, mechanical behavior and longer durability. The adiabatic temperature rising of HBC dam concrete is reduced by 3-5°C at the same mixing proportion. The crack resistance analysis shows that the HBC dam concrete possesses good crack resistance ability. HBC dam concrete is a new dam concrete with low-heat and high crack resistance, and is expected to be widely used in the mass concrete projects of water resource engineering.
