Abstract
The aim of this study is to evaluate the durability of Self-Compacting Concrete (SCC) incorporating metakaolin (mk). For the mixture preparation, cement or limestone powder were replaced by mk at different levels. The estimated properties (open porosity, sorptivity, water and gas permeability, chloride penetrability) were evaluated against a reference mixture (without mk). The incorporation of mk improved durability, but not the near surface water permeability of the concrete. Equations expressing the effect of the replacement level on the examined properties were formulated, whenever appropriate. The most enhancing effect of mk as a replacement material was observed in the chloride penetration resistance.
