EXPERIMENTAL INQUISITION OF CONCRETE AFTER THE REPLACEMENT OF CEMENT WITH CERAMIC WASTES AND METAPHORICAL STUDY OF THEIR PROPERTIES WITH THE NOMINAL CONCRETE

Objective: The aim of this investigation was to observe the change in the properties of concrete after the partial replacement of cement with the marble dust powder MDP. In addition to this, the use of ceramics like tiles and marbles is increasing with the gradual increase in the population day by day. This hike in the use of ceramics has resulted in the production of ceramic wastes to a larger extent. The marble powder waste generated from marble industries and construction sites is useless and is thus disposed off into the landfills, thereby, degrading the environmental health. The proper use of marble dust powder in concrete makes it ecofriendly and cost effective which is one of the objectives of this study. Method/Statistical analysis: The M25 grade of concrete was used for the research work. The cement was replaced with MDP by 10%, 15%, 25% and 30% and the concrete cubes were cured for 7 and 28 days. The compression strength, split tensile strength and flexural strength of the concrete cubes with and without MDP was checked by conducting tests on them. The results obtained were compared to the results obtained from nominal concrete. Findings: The mechanical properties of concrete with MDP were improved. The strength of concrete was maximum at 10% replacement. It was found out to be decreasing with the increase in the MDP percentage above 25%. Applications: Marble dust powder is produced during the cutting process of marble. It is the solid waste material which can be used as filler in concrete. Marble powder can act as replacement material for cement as well as aggregates in making concrete. It not only enhances its properties but also makes it ecofriendly and cheap which can help the fraternity of civil engineers to reduce the effect of concrete on environmental health and built the economical infrastructures
