UTILIZATION OF MUĞLA FLY ASH AND QUARTZ DUST IN ENGINEERED CEMENTITIOUS COMPOSITES PRODUCTION AT HIGH VOLUMES

Concrete, because of its brittle nature, is very prone to cracking especially under induced tensile stresses. Those cracks make the material vulnerable to external influences. Water penetrating through the cracks yields various durability issues that shorten the service life of the concrete. However, contrary to ordinary concrete, in Engineered Cementitious Composites (ECC) formation of multiple and tight micro-cracks under loading yields to high ductility, energy absorption capacity and durability. Besides, these tiny cracks also exhibit self-healing properties with the help of a high amount of binding materials available in composite composition. Within the scope of this study, in the design of the ECC, two different mixtures with low and high fly ash amounts were produce. Furthermore, waste materials of the Muğla region which cause environmental pollution and have little or no commercial value were used in ECC production. Mechanical strength values and self-healing properties of the specimens were investigated at the scope of the study.
