具有良好工作性能的自密实混凝土是钢板-混凝土结构能够实现的前提。自密实混凝土的早期力学性能是钢板-混凝土结构设计的重要参数。本文通过实验的方法对自密实混凝土的工作性能和早期力学性能进行了研究。配制出满足钢板-混凝土结构要求的自密实混凝土,并给出钢板-混凝土结构设计所需的自密实混凝土早期力学参数。研究成果可以指导钢板-混凝土结构内部自密实混凝土的施工以及钢板-混凝土结构的设计和施工。
Self-compacting concrete with good workability is a prerequisite for the realization of steel-concrete structures. The early mechanical properties of self-compacting concrete are important parameters in the design of steel-concrete structures. In this paper, the working performance and early mechanical properties of self-compacting concrete are studied by means of experiments. The self-compacting concrete satisfying the requirements of steel-concrete structure was prepared and the early mechanical parameters of self-compacting concrete required for the design of steel-concrete structure were given. The research results can guide the construction of self-compacting concrete in steel-concrete structures and the design and construction of steel-concrete structures.
