Özet
In this study, the effects on high performance mortar (HPM) of synthetic wollastonite (SW) mineral were researched. Through this work, firstly, wollastonite was synthetically obtained by a particular production method. Secondly, SW was utilized as cement replacement material from 0 to 12% by 3% steps of increment in the production of HPM. After determination of slump flow diameters of HPMs, mechanical and durability properties were observed at 28 and 90 days. Additionally, microstructural performance properties of HPMs designed with SW in the ratios 0, 9, and 12% was specified with TGA/DTA and FTIR analysis as well as SEM/EDX and XRD analysis. The test and analysis results showed that SW decreased the workability of HPMs. The improvement of the mechanical and durability properties of HPMs proceeded up to 9% of SW. Microstructural analysis showed that development effect of SW on the HPM can be attributed to its needle-shaped structure.
