OPTIMUM PARTIAL REPLACEMENT OF CEMENT IN CONCRETE WITH WASTE MARBLE DUST IN CONJUNCTION WITH SUPER PLASTICIZERS

Efforts have been made over years to make concrete production sustainable and environment friendly . Notion of new materials as substitute for the conventional materials have supported these efforts to a large extent. In the present investigation ,m arble d ust obtained after processing of marble waste has been used as a filler material i.e. as replacement of fine aggregate. This study investigates the optimum partial replacement of cement in concrete with marble dust in conjunction with super - plasticizers. This investigation proved the feasibility of marble dust as an economic and eco - friendly replacement of cement. The slump and compressive strength of the concrete was improved when 5%, 10% & 15% of weight of cement was replaced with marble dust in preparation of M20 concrete. This paper provides the scope for more research that if the marble dust is used as a replacement of cement in conjunction with super - plasticizers , the problem of sustainable, economical and environment friendly concrete can be resolved.
