Evaluation of environmental wastes in building material

Abstract

In this study, it was produced composite material by using environmental waste sources of Turkey in brick clay. It was selected Resadiye Clay as main material and boron waste of Kütahya-Emet Boron Works, fly ash of Seyitömer Power Plant and wastewater treatment sludge of Ankara- Tatlar Wastewater Treatment Plant as filling materials. Obtained samples from various resources were firstly grinded, then well mixed in different ratios, moistened and poured into the molds. In the experiments mass percent of boron waste, fly ash and treatment sludge were changed in composites respectively between (2.5-20%), (2.5-10%) and (0-10%) and brick clay was used between 75-85%. Shaped samples which have 50x50x50 mm dimension were dried at room temperature for 24 hours and after that at 105±1 °C for 12 hours respectively. Specific bulk density, drying shrinkage, water absorption, compressive strength and loss of mass tests were carried out. At the end of the tests, it has been conclused approach to the TS EN 771-1 brick standard physical parameters partly also, it has been produced energy conservative and environmentally friendly composite material.
