摘　　要：对花岗岩、玄武岩、灰岩、砂岩和大理岩等5种水工混凝土人工骨料的物理力学性质、化学属性、长期吸水特性、热学参数等进行分析,对比研究骨料的特征参数,为掌握骨料特性,分析其在混凝土中的行为以及水工混凝土配合比的科学设计、骨料料场的合理选择等提供技术支持,以实现水工混凝土的体积稳定性。The physical and mechanical properties, chemical properties, long-term water absorbing characters and thermal parameters of granite, basal4 limestone, sandstone and marble are analyzed herein by experiments. These five kinds of rocks are usually used as artificial aggregate of hydraulic concrete. The comparisons of characteristic parameters of these artificial aggregates provides a technical support to understand the characteristics and behavior of aggregates in concrete, design the mix proportion of hydraulic concrete scientifically and select the sources of aggregate material rationally, and to achieve the volume stability of hydraulic concrete.
