摘要：In this paper, mechanical and permeability related properties of Self Compacting Concrete (SCC) containing metakaolin (MK) were evaluated and their interrelationships discussed. For this purpose, different types of mixture were prepared with different amounts of MK and ordinary Portland cement (OPC) was replaced by 5, 10, 15 ... 30% of MK. When increasing the percentage of MK, the mechanical and permeability related properties of SCC considerably improved. The result showed that the SCC sample incorporating the cement with 20% MK showed better workability, mechanical and permeability related properties than that of the normal SCC sample (without MK). One interesting point was observed that the UPV and other mechanical properties were perfectly fitted in the regression analysis. It is used to indicate that the strong interrelationships were presented with each other. In addition, the resistance to chloride ion penetration was directly varied with the SiO2 + Al2O3 + Fe2O3 / CaO ratio. A good result was obtained for resistance to chloride ion penetration in SCC at the SiO2 + Al2O3 + Fe2O3 / CaO ratio of 1.1.
