Abstract

Waste handling and management is the major problem faced by the countries in the modern era. Concrete demolition waste has been one among the source of creating environmental pollution. There have been many strength and durability studies taken place to analyze the concrete made with coarse aggregate which has recycled from the old concrete structures and proved high strength compared to the concrete made with new materials. Those research works are limited in analyzing of finer divisions of the concrete made with the aggregates which has recycled. This paper concentrates the applications of Recycled Fine Aggregate (RFA) as partially or complete replacement instead the fine aggregates available naturally to prepare the concrete. The strength of the concrete partially replaced by RFA was investigated and the results suggest that 60% substitution is optimal.
