Strength Chracteristics of Self-Compacting Concrete Partially Replaced With Waste Marble Powder

Self−compacting concrete is one of the most revolutionary developments in concrete research; this concrete is able to flow and to fill the most congested places of the form work without vibration. This research work presents properties of self-compacting concrete after replacement of fine aggregate with powder of waste marble at different percentages (0%, 10%, 20%, 30% 40% and 50%). In this study, the waste marble powder, finer than 4.75 mm is used for the replacement of fine-aggregate. And with the increment in the dose of waste marble powder, the workability of SCC is increased. For the dose of waste marble powder replacement 30%, the fresh properties observed were good in comparison of dose 0%, 10%, 20%, 40% and 50% of waste marble powder replacement. The compressive strength test is conducted at different mix proportion of SCC with waste marble powder and the highest compressive strength has been found at 30% powder of waste marble replacement as compared to other mixes at 7 and 28 days ages.
