dc.description.abstractIn this study, synthetic wollastonite (SW) mineral was produced by using a new production method. This method which quartz and calcite minerals are used as raw materials, is 3-step wollastonite production method consisting of mechanochemical process, hydrothermal process and solid state reaction process. It was proved that the material (SW) produced with the help of this new method is wollastonite by using SEM, XRF and XRD analysis. The effect of SW on the mechanical and microstructural properties of cement mortar (CM) were experimentally investigated. The CMs were produced without SW as control mortar and by using SW with the ratios of 3%, 6%, 9%, 12% and 15% instead of cement. Compressive and flexural strength tests were conducted at 7 and 28 days. In addition, SEM/EDX, TGA/DTA and FTIR analysis were applied to mixtures incorporating SW in the ratios of 0%, 3%, 9% and 15% at 28 days. Test results indicate that mechanical performance of CMs improved up to 9% SW content. However, CMs with 12% and 15% SW had higher compressive and flexural strength than the control mortar. Microstructural analysis demonstrated that improvement in the strength characteristics of CMs incorporating SW can be explained with the acicular particle structure of SW. In addition, according to TGA/DTA and FTIR analysis, it is observed that CaCO3 in CMs decreased with the increase of SW. © 2019 Elsevier Ltd
