MINERALOGICAL AND PETROGRAPHICAL ANALYSIS OF COMPOSITE GLASS FIBER ADDED LIME MORTARS

Abstract

Lime and brick dust are important and unique building materials commonly used in the construction of historical structures. Over time, different products and additives have been added to mortar mixtures to improve and modify certain characteristics. With the advancement of technology, composite materials have been developed when pure materials were insufficient, and their areas of use have expanded over time. The aim of this study is to contribute to the literature by adding materials such as glass fibers to lime mortar to create potential for new generation composite materials. The influence of these materials on the mineralogical structure of the produced mortars has been determined. Glass fiber materials exhibit high corrosion resistance and strength, making them resistant to outdoor conditions such as wind, temperature, and cold. They are widely used in the construction sector, especially in floorings. In this study, the mineralogical and petrographic analyses of lime mortar reinforced with composite glass fibers were examined. XRD analysis was performed for mineral composition and identification, FESEM analysis was used to define the morphology, microstructure, and chemical composition of the mortars, and EDS analysis was conducted to determine the chemical characterization of the mortars. As a result of these analyses, it was determined that glass reinforced mortars have a calcite mineral structure containing a high amount of Ca, C, O, Si elements, as well as Mg, Al, and small amounts of Fe, K, S elements.
