Utilization of Marble and Boron Waste in Brick Products

Abstract

In this study, usability of marble and boron wastes as alternative raw materials in the production of bricks was investigated. They were used in different ratios to prepare samples.  Marble waste in concentrations of 5, 10, 15 and 20 wt% were added to the boron waste. Afyon brick clay was used as a binder in 10 wt%. Specimens were shaped by hydraulic press and fired at temperatures from 850 to 1050 °C for 4 hours. The crystalline structure and morphologies of the samples are characterized by X-ray powder diffractometer (XRD) and scanning electron microscopy (SEM), respectively. Flexural strengths of samples were measured. The reasonable mechanical properties have been obtained from the brick sample containing 5 wt% marble waste, 85 wt% boron waste and 10 wt% clay sintered at 1050 °C for 4 hours.
