Özet: In this study, the effects of natural wollastonite obtained from Finland on strength and durability properties of HPM of wollastonite were investigated. In the production of HPM, wollastonite mineral was added to the mixture at 3%, 6%, 9%, 12% and 15% by keeping the water/binder ratio constant. In addition, the workability of the mixture was achieved by means of a high range water reducing admixture (SP). Compressive, flexural and ultrasonic pulse velocity tests were conducted at 3, 7, 28 and 90 days while sorptivity and gas permeability tests were applied at 28 and 90 days. According to the obtained results of these tests, it was observed that the mixtures containing 3% wollastonite had the recuperation in performance for all experiments. Compared to the control mortar, the mixture containing 6% wollastonite indicated the better results whereas the reduction in performance was observed in the comparison the mixture containing 3% wollastonite.
