Research on working property and early age mechanical property of self-compacting concrete used in steel-concrete structure

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。

Background： Self-compacting concrete that has good working property is the prerequisite of steel-concrete structure. The early age mechanical property of self-compacting concrete is the important parameter when design steel-concrete structure. Purpose： This paper attempts to research the working property and early age mechanical property of self-compacting concrete. Methods： Test is used to research the working property and early age mechanical property of stir-compacting concrete. Results： Self-compacting concrete that could meet the requirement of steel-concrete structure has been mixed and parameters of early age mechanical property of self-compacting concrete which is necessary for design of steel-concrete structure have been presented. Conclusions： Base on the results, this paper can guide the construction of self-compacting concrete in steel-concrete structure and the design and construction of steel-concrete structure.
