Abstract
Three repair materials were prepared using cement-based, geopolymeric, or geopolymeric containing steel slag binders. Their mechanical performances such as compressive strength, bond strength and abrasion resistance were examined experimentally. The test results showed that the geopolymeric materials had better repair characteristics than cement-based repair materials, and the addition of steel slag could improve significantly the abrasion resistance of geopolymeric repair. By means of scanning electron microscopy (SEM) it can also be concluded that the steel slag was almost fully absorbed to take part in the alkali-activated reaction and be immobilized into the amorphous aluminosilicate geopolymer matrix.
