基于流变学特性的SCC配合比设计研究进展

Advances of the research on self-compacting concrete mixture design based on rheological characteristics

基于流变学特性的配合比设计有利于建立标准的自密实混凝土配合比设计流程。初始流动屈服应力和塑性黏度是描述自密实混凝土流变学特性的两个基本参数,坍落流动度试验结果与流变学特性参数存在定量关系。然而我国对自密实混凝土流变学特性的研究较少。详细介绍了混凝土流变学特性和基于流变学特性的自密实混凝土配合比设计研究进展,供实际应用参考。

The mixture design based on rhoological characteristics is beneficial to set up standard self-compacting concrete mixture design flow. The yield stress and plastic viscosity are two fundamental parameters describing the behavior of self-compacting concrete.The standard slump flow test gives two results,which are related to the theological parameters.However, the study on rheological characteristics of self-compacting concrete is less at abroad.The recant advances on concrete rheological characteristics and relative mixture design for self-compacting concrete were re- viewed.It is hoped that the study may provide some reference for practical engineering.
