This paper describes with experimental study on properties of mortar using recovered fine aggregate. Within the range of the present tests, compressive strength of mortar using recovered fine aggregate lower than compressive strength of original mortar. The causes of the strength reduction when mortar using recovered fine aggregate are an increase of air content of mortar caused by change in grading of fine aggregate and a decrease of fine powder of fine aggregate. However, when recovered fine
