石灰石粉在水工混凝土中的应用研究综述

Review of applied research on limestone powder in hydraulic concrete

在水工混凝土中应用石灰石粉,是绿色混凝土的发展方向之一。阐述了在水工混凝土中掺用石灰石粉国内外的研究现状,分析了掺入石灰石粉对水工混凝土宏观及微观性能的影响,总结了研究中存在的问题与不足,提出了掺入石灰石粉后,在配合比设计、水泥基材料的水化动力学模型、抵抗接触溶蚀、渗透溶蚀能力、硅灰石膏破坏的影响及作用机理等方面的研究方向。

The research status of mixing limestone powder in hydraulic concrete at home and abroad is investigated.This paper covers an analysis of its influence on macro-performance and micro-performance of hydraulic concrete when limestone powder are added.The problems and deficiencies in the former researches are concluded and new research directions of concrete adding limestone powder are proposed such as new proportion design,hydration kinetics mechanism of cement-based materials,the effect and mechanism of anti contact dissolution,anti leakage dissolution and damage caused by thaumasite.
