石灰石粉在水泥基材料中的作用及对其耐久性的影响
Role of Limestone Powder and Its Effect on Durability of Cement-Based Materials
摘要
Abstract
Limestone powder (LP), as a supplementary cementitious material (SCM), can have a certain influence on the hydration, microstructure and durability of cement-based materials. This paper reviewed the action mechanism of limestone power in cement-based materials (i.e., nucleation effect, filler effect, dilution effect and chemical effect). LP accelerates the hydration reaction, improves the pore structure and ITZ, and enhances the properties of cement-based materials. Instead, LP with larger sizes or excessive additions shows a dilution effect on the properties of cementitious materials. Moreover, this paper also represented the four action mechanisms of LP for the durability properties,i.e., permeability, carbonation resistance, sulfate corrosion, frost resistance and reinforcement corrosion. In addition, further researches on the addition of limestone power into cement-based materials were also proposed.关键词
