 note = {A successive research for aggregates on Okinawa Islands is now undertaken to make a good correlation with the concrete works, and this paper presents partial remarks of the investigation. Mostly, this time, the beach sands and crushed stones, being used for concrete works necessarily, were collected in the southern and middle parts of the Okinawa main island. The laboratory tests were performed according to the standard of the Japan Society of Civil Engineers. Both the fine and coarse aggregates, especially the later, are generally poor comparing with those of Japan, consequently it is emphasized to develope the unique specifications by using those representative aggregates to make a good correlation with the concrete works on Okinawa Islands., 紀要論文},
