Utilization of ceramic wastes in the construction sector

Abstract

Ceramic wastes causing a serious problem are polluting the environmental problem in Eskisehir Region, Turkey. In this paper, were studied three wastes, ceramic mud wastes (CMW), crushed ceramic tile wastes (CCTW) and ceramic tile dust wastes (CTDW). The waste reused as an alternative construction materials in the backfill material with lime, zeolite, and cement, and as a road sub-base material. with natural soil, sand and crushed aggregate, and as a concrete block material with cement mixture, and as an improving expansive soil material with Na-bentonite. According to the results of these experiments, a remarkable decrease of zinc (Zn) was noted in the content of CMW from ceramic refinery plant and it was reused as a construction materials. CCTW 3 were used for cement mixture production in substitution of aggregates with dosage of 175kg/m(3). Swelling pressure and swelling percent of Na-bentonite clay mixed with 40% CCDW decreased 86% and 57%, respectively.
