Abstract
As a result of rapid urbanization especially in the developing nations, there is increasing demand for sustainable construction materials. This coupled with increasing cost of the materials and environmental degradation as a result of mining of aggregates, there has been growing interest in the reuse of construction and demolition waste (CDW). Reclaimed fine aggregate (RFA), refers to fine aggregate derived from crushed concrete waste. It is being considered as a possible alternative to natural river sand in concrete production. This study assesses the integrity of RFA as a viable material for concrete by focusing on its physical characteristics. Study is light for comparison with require limits from standards. It is therefore concluded that RFA is unsuitable for complete substitution of natural aggregate in concrete production. However, it is recommended as partial replacement for natural aggregate in concrete production.
