摘要

25 CONTROLLED DETERIORATION OF NON-REINFORCED CONCRETE ANCHORS ABSTRACT A CONCRETE FON-NULATION WHICH UNDERGOES CONTROLLED DETERIORATION IN WATER, THAT CAN BE USED FOR MAKING ANCHORS FOR RELEASABLY TETHERING SUBMARINE DEVICES AT THE SEABED. THE ANCHOR MAY HAVE HANDLES FOR A DEVICE RELEASE 5 MECHANISM OR A CENTRAL HOLE FOR A CENTRAL DEVICE RELEASE MECHANISM. THE FORMULATION INCLUDES ADDITIVES WHICH CAUSE THE CEMENT TO TRANSFORM INTO NON- BINDING THAUMASITE OVER A PRE-SET PERIOD OF TIME, LEAVING ONLY NATURAL MATERIAL ON THE SEAFLOOR.
