石灰石粉对水泥和减水剂相容性的影响综述

Impact of Limestone Powder on Compatibility of Cement and Water Reducer

在自密实混凝土应用日趋广泛的今天,掺入石灰石粉成为改善其工作性的重要措施,越来越多的学者开始关注加入到胶凝材料体系中的石灰石粉对体系和减水剂相容性的影响。该文从石灰石粉掺量、细度、不同减水剂种类以及石灰石粉和其他种类混合材料的影响差异4个方面总结石灰石粉对水泥和减水剂相容性影响的研究现状。

With the increasing adoption of self-compacting concrete,limestone powder has been one of the important measures to improve its workability. More and more scholars begin to pay attention to the influence of limestone powder added to the cementitious material system on the compatibility of the system and waterreducer. In this paper, the study status on the impact of limestone powder on cement and water reducer is summarized from the four aspects of limestone powder content, fineness, waterreducer types and impact difference of limestone powder and other types of mixed materials.
