DEVELOPMENT OF A TWO-CONPONENT BACKPACKING SYSTEM

A COMPOSITE SYSTEM CONSISTING OF THIN-WALLED SHELLS (TIN CANS AND/OR HOLLOW SPHERES) AND LIGHT-WEIGHT CELLULAR CONCRETE AS THE SURROUNDING MATRIX MATERIAL WAS TESTED AND ANALYZED AS A BACKFILLING SYSTEM. THIS STUDY INCLUDED STATIC EVALUATION OF LOAD-DEFORMATION CHARACTERISTICS, DEVELOPMENT OF AN IN SITU PLACEMENT TECHNIQUE, ANALYSIS OF WATER SATURATION PROPERTIES, AND AN OVERALL COST EVALUATION. THE RESULTS FROM THE TEST PROGRAM INDICATED THAT THE COMPOSITE SYSTEM HAD IMPROVED ENERGY ABSORPTION QUALITIES AND BETTER DEFORMATION PROPERTIES THAN PLAIN CELLULAR CONCRETE, WHICH IS ONE OF THE MATERIALS PRESENTLY USED FOR BACKPACKING. A SUITABLE PLACEMENT TECHNIQUE WAS DEVELOPED FOR THE SYSTEM, AND, IF USED IN LARGE QUANTITIES, MATERIAL AND PLACEMENT COST WOULD BE COMPATIBLE WITH THE PLAIN CELLULAR CONCRETE SYSTEM. /AUTHOR/
