A STUDY ON PARTIAL REPLACEMENT OF CEMENT BY WASTE MARBLE DUST AND FINE AGGREGATE BY TYRE RUBBER WASTE IN CONCRETE

Leaving the waste materials to nature straightforwardly can cause ecological issue. Henceforth the reuse of waste material has been underscored. Marble is one of the vital materials utilized in the development business. Marble powder is delivered from handling plants amid the sawing and cleaning of marble squares and around 20 - 25% of the prepared marble is transform into powder structure. Overall creation of tyre increments because of increment of vehicle industry, it is hard to arrange the waste tyre as the accessibility and limit of spaces of landfill diminishes. In this examination, execution of waste materials, waste marble dust and tyre rubber waste as a halfway substitution of cement and fine aggregates for M30 grade of concrete is learned at various rates and its impact on solid properties like Compressive Strength, Flexural Strength and Split Tensile Strength is examined. The waste marble dust was utilized in the level of (20%, 25%, and 30%) and tyre rubber waste was utilized in the level of (5%, 10%, and 15%). Results showed that substitution of waste marble dust to the cement and tyre rubber waste to the fine aggregates in concrete at proportions 20% and 5% there was no impact on the properties of concrete however for different proportions changes were watched.
