Effect of the Addition of ZrSiO4 on Alkali-Resistance and
Basalt fiber has been used as a reinforced material in cement-based materials because it has higher mechanical strength and cheaper than common silicate based glass-fibers. However silicate-based glass fibers have low alkali resistance especially in cement matrix composite. In this work we studied the improvement of alkali resistance by addition of zirconium silicate (ZrSiO4) in original
