Abstract
This research aims to study the possibility of recycling stone cutting slurry in concrete production as a replacement of potable mixing water. Physical and chemical characteristics of slurry were determined. The effects of replacements were investigated by measuring identifiable concrete and mortar parameters, such as workability, compressive, tensile, and flexural strength for concrete, and compressive, flexural strength and expansion due to alkali aggregate reactions for mortar. The results showed an improvement of all concrete and mortar characteristics: concrete compressive strength had increased by 21 %, flexural strength by 18 %, mortar compressive strength by 11 %, and flexural strength by 11.7 %. Slump values of concrete were reduced by 58 %. Such results emphasized the feasibility of reusing slurry sludge in concrete and mortar production.
