Mechanical properties of sustainable concrete modified by adding marble slurry as cement substitution

Abstract

Industrial waste has been rapidly increased day by day because of the fast-expanding population which inappropriately dumps the waste resulting in environmental pollutions. It has been recommended that the disposal of industrial waste would be greatly reduced if it could be incorporated into concrete production. The basic objective of this investigation is to examine the characteristics of concrete using marble slurry as binding material in proportions 5%, 10%, 15%, 20%, 25%, and 30% by weight of cement. Many properties have been reviewed in the current paper; the results observed from the various studies depict that replacement of marble slurry to a certain extent enhances strength properties of the concrete but simultaneously decreases the slump value with the increase of replacement level of marble slurry.
