Recycling of stone cutting sludge in formulations of bricks and terrazzo tiles

Abstract

This study examines the possibility for enhancing the use of stone cutting sludge waste in the production of building bricks and terrazzo tiles, which would reduce both the environmental impact and the production costs. Stone cutting wastes in the form of sludge is currently generated at several factories in Jordan. At the Samara factory, incorporation of the sludge in the batch formulations of bricks and terrazzo tiles was examined. The physicochemical and mineralogical characteristics of the sludge were analyzed to identify the major components. Results indicated that the sludge generated from stone cutting could be used in producing concrete bricks. Mixtures of aggregates with added amounts of sludge were used successfully to produce non-load bearing bricks. Sludge was also used to produce terrazzo tiles and the results indicate that the transverse strength, water absorption and tile measurements, for all the taken samples, comply with Jordanian standards. The transverse strength decreased while water absorption increased as the sludge ratio increased.

Influência Dos Resíduos Da Poluição Atmosférica Na Saúde Respiratória De Motoristas De Transporte Coletivo Urbano Em Uma Cidade Do Pontal Do Paranapanema

“…Muitos materiais, devido a sua distribuição granulométrica, são utilizados para controlar a plasticidade típica das matérias-primas argilosas e obter um melhor nível de trabalhabilidade com um menor consumo de água. A quantidade de resíduos adicionados a matriz pode variar entre 10 e 60% em peso (BILGIN et al, 2012;AL-ZBOON et al, 2010).…”

A Suppression Method for Elution of F−, [B(OH)4]−, AsO43−, and CrO42− from Industrial Wastes Using Some Inhibitors and Crushed Stone Powder

“…However, because of the continuous depletion of natural resources, the limited landfill land available, and increased transportation costs, there is a demand for the effective utilization of CSP. In recent years, there have been an increasing number of studies that focus on the recycling of CSP in concrete instead of in silica powder or sand [35][36][37][38][39]. However, further utilization of CSP in inhibiting the elution of hazardous ions is rarely found.…”

Characterization of Sugarcane Bagasse ash Waste for Its Use in Ceramic Floor Tile

“…In recent years, the building materials industry has become a promising alternative for the recycling of solid waste materials (Badiee et al, 2008;Wei et al, 2009;Al-Zboon et al, 2010). Some reasons for this are: i) the ceramic industry utilizes large amounts of natural raw materials; ii) the building materials permit large variability of their chemical and mineralogical compositions; and iii) toxic substances could be inertized in the sintered ceramic matrix.…”
