Use of Waste Material for Sustainable Self Compacting Concrete

Abstract

This paper explores one of the major environmental concerns which is disposal or recycling of the waste materials”. “Marble processing plants produce millions of tons of waste dust in the powder form every year”. “Having a considerable high degree of fineness in comparison to cement, marble powder may be utilized as filler for the production of Self-Compacting Concrete (SCC)”. “This research paper aimed at developing an eco-friendly and workable self-compacting concrete with the maximum amount of marble powder”. For this, a control mix and four other mixes with varying amounts of marble powder as 5%, 10%, 15%, and 20% are prepared. These mixes are then tested for their fresh properties by slump flow, j-ring, and V-funnel at T 5minutes. Compressive strength is used to evaluate the hardened concrete. It was found that up to 15 % marble powder addition, the fresh and hardened properties of the concrete mix did not vary considerably. However, it was also found that with the addition of marble powder the compressive strength decreased.
