FUNDAMENTAL STUDIES ON THE FABRIC OF SOIL-CEMENT MIXTURE AND ITS MECHANICAL PROPERTIES

THE RELATIONSHIP BETWEEN THE STRUCTURE AND MECHANICAL PROPERTIES OF SOIL CEMENT MIXTURES IS DISCUSSED FROM MICRO- AND MACROSCOPIC STANDPOINTS. FIRST, THE EFFECT OF THE INTERACTION OF CLAY MINERALS AND CEMENT ON THE STRENGTH CHARACTERISTICS OF COMPACTED MIXTURES IS TREATED EXPERIMENTALLY, CHIEFLY FROM THE MICROSCOPIC STANDPOINT. FOUR PROBLEMS ARE INVESTIGATED THROUGH THE USE OF X-RAY DIFFRACTION, THERMAL ANALYSIS, PH TESTS, OPTICAL MICROSCOPES, AND UNCONFINED COMPRESSION TESTS. TEN MAJOR CONCLUSIONS EMERGE FROM THIS ANALYSIS. FROM THE MACROSCOPIC STANDPOINT, THE QUANTITY, SIZE DISTRIBUTION, AND PHYSICAL PROPERTIES OF CLAY POCKETS CONTAINED IN SOIL CEMENT SPECIMENS ARE FOUND TO HAVE A SIGNIFICANT EFFECT ON THE MECHANICAL PROPERTIES OF SOIL CEMENT. SECOND, THE INFLUENCE OF THESE FACTORS ON CREEP DEFORMATION CHARACTERISTICS IS DISCUSSED ON THE BASIS OF EXPERIMENTS. THE EFFECT OF A PHYSICAL PROPERTY (MOISTURE CONTENT) OF CLAY POCKETS EXISTING IN THE PRODUCTION OF SPECIMENS ON THE SUBSEQUENT FORMATION OF MACROSCOPIC STRUCTURE IN CLAY CEMENT MIXTURES IS ESTIMATED FROM VISCOELASTIC BEHAVIOR. SEVERAL EXPERIMENTAL DISCUSSIONS ARE INTRODUCED REGARDING THE VISCOELASTIC PROPERTIES OF GRANULAR SOIL CEMENT MIXTURES TO ELUCIDATE THE ROLE OF CLAY POCKETS IN SOIL CEMENT MIXTURES. FIVE CONCLUSIONS ARE DRAWN FROM THESE EXPERIMENTS AND ESTIMATES. THIRD, BECAUSE OF THE SERIOUSNESS OF SHRINKAGE CRACKING IN SOIL CEMENT PAVEMENTS, THE EFFECT OF CLAY POCKETS ON SHRINKAGE CHARATERISTICS IS TREATED. TWO ATTEMPTS ARE MADE TO ESTIMATE SHRINKAGE STRESSES IN SOIL CEMENT. SIX NEW FINDINGS FROM THIS ANALYSIS ARE REPORTED.
