RESEARCH ON ARTIFICIALLY SEDIMENTED CLAYS, PHASE REPORT NO. 1: ONE-DIMENSIONAL CONSOLIDATION CHARACTERISTICS OF AN ARTIFICIALLY SEDIMENTED MARINE CLAY

THE ONE-DIMENSIONAL CONSOLIDATION CHARACTERISTICS OF AN ARTIFICIAL CLAY, PRODUCED BY SEDIMENTING BANGKOK CLAY IN SODIUM CHLORIDE SOLUTION, WERE INVESTIGATED IN THE LABORATORY. THE LOAD INCREMENT RATIO WAS VARIED FROM 0.25 TO 2.0 FOR LOAD INCREMENT DURATIONS WHICH RANGED FROM 12 HOURS TO 7 DAYS. IT WAS FOUND THAT THE COMPRESSIBILITY OF THE ARTIFICIAL SOIL IN THE VIRGIN COMPRESSION RANGE WAS NOT SIGNIFICANTLY AFFECTED BY LOAD INCREMENT RATIO OR LOAD INCREMENT DURATION. THE RATES OF PRIMARY AND SECONDARY COMPRESSION, HOWEVER, WERE BOTH FUNCTIONS OF THE LOADING CONDITIONS. THE DIFFERENCES IN BEHAVIOUR BETWEEN THE ARTIFICIAL CLAY AND A NATURAL CLAY DEPOSIT CAN PROBABLY BE EXPLAINED IN TERMS OF THE DIFFERENT MAGNITUDES OF BOND STRENGTH DEVELOPED DURING THE PERIODS OF SEDIMENTATION AND COMPRESSION. THE RELATIVELY SHORT PERIOD OF TIME INVOLVED IN PRODUCING ARTIFICIAL CLAYS RESULTS IN A LOWER BOND STRENGTH WHICH PERMITS GREATER EASE OF SLIDING AT THE PARTICLE CONTACT POINTS THAN IN A NATURAL DEPOSIT. /AUTHOR/
