Get PriceThis study investigated the mechanical behavior of normal strength (NS) and high strength (HS) concrete containing recycled fine aggregates (RFAs). A high slump mixing design was employed which may be potentially used as filled structural concrete. The compressive strength tensile strength and elastic modulus were measured according to the RFA replacement ratio and curing time.
