Abstract :Experimental studies concerning the improvement of the local base materials of Okinawa Islands has been made, and a part of the investigative results on Coral Reef Rock was reported before. Present paper describes, first, the effect of the compacting method on the density and strength of Coral Reef Rock of Okinawa island. Those methods are, 1) Manual Impact Compaction-JIS and Proctor method, 2) Laboratory Manual Kneading Compaction by Harvard Miniature Device, and 3) Laboratory Static Compaction by a jack. Moisture-density relations and 7 day-cured-uncon-fined compressive strengths of those compacted samples are presented and discussed. Secondly, the Coral Reef Rock stabilization test results by some chemicals are presented. The mixed and statically compacted samples are soaked in water for the slaking test. The treatment with a chemical; Di-anmonium Hydrogen Phosphate (NH4)_2 HPO_4, appears to be highly evaluated.
