对自密实轻骨料高性能混凝土的配合比优化设计进行了系统的试验研究，根据自密实混凝土和轻骨料混凝土配合比设计原理，采用绝对体积法，成功研制出强度等级为LC30LC50的自密实轻骨料高性能混凝土。对影响自密实轻骨料高性能混凝土工作性和力学特性的主要因素进行了定量分析，获取了自密实轻骨料高性能混凝土的优化配合比，所得结论为自密实轻骨料高性能混凝土的进一步研究与应用提供了参考。

The mixtures of self-compacting light-aggregate concrete （SCLC） were systemically experimented. Based on the principles of designs of self-compacting and light-aggregate concrete mixtures, SCLC of middle strength （LC30～LC50） was developed with the absolute volume method. Several factors that significantly affect the workability and mechanical properties of SCLC were analyzed, as well as some advices were given to choose the optimal values and optimum matching ranges of the main design parameters. The optimal mixtures of LC30～LC50 which may contribute to the further analysis and application of SCLC were given.
