CLAY MINERALS IN FOUNDATION ENGINEERING - THE CHEMICAL AND MINERALOGICAL TESTING OF FINE GRAINED SOILS

THE MECHANICAL BEHAVIOR OF SOILS IS CALCULATED BY THE CONSTRUCTION ENGINEER BY MEANS OF COEFFICIENTS WHICH ARE DETERMINED IN FIELD AND LABORATORY TESTS. THE GEOLOGIST PROVIDES THE CONSTRUCTION ENGINEER WITH INFORMATION ON THE GEOLOGICAL AND PETROGRAPHIC STRUCTURE OF THE SUBSOIL, THE ORIGIN OF THE SOIL, AND GROUND WATER CONDITIONS. THE BEHAVIOR OF COARSE GRAINED MATERIALS CAN BE DETERMINED TO A LARGE EXTENT FROM PROPERTIES SUCH AS ELASTICITY, FRICTION AND HYDRO-MECHANICS. ON THE OTHER HAND, THE MECHANICAL BEHAVIOR OF SOILS RICH IN CLAY (FINE GRAINED SOILS) IS MAINLY DETERMINED BY THE CHEMICAL AND PHYSICAL PROPERTIES OF THE CLAY/WATER SYSTEM. CLAY MINERAL ARISES PREDOMINANTLY THROUGH WEATHERING AND IS THEREFORE WIDESPREAD. IT CAUSES SERIOUS LANDSLIDES AND DAMAGE BECAUSE OF ITS TENDENCY TO SWELL. CHEMICAL AND PHYSICAL TESTS ARE NEEDED TO CHARACTERIZE FINE GRAINED SOILS. THE ARTICLE IS BASED ON THE WORK OF VAN OLPHENS AND DEALS WITH THE MOST IMPORTANT CHEMICAL AND PHYSICAL PROPERTIES OF THE CLAY/WATER SYSTEM. /TRRL/
