BENDING AND TESILE STRENGTH CHARACTERISTICS OF FIBER-REINFORCED CEMENT TREATED SOIL

Abstract

The fiber reinforced cement treated soil was originally developed as a geomaterial that improves toughness of brittle cement treated clay by inclusion of fibrous materials. The bending strength was increased by fiber inclusion irrespective of the physical properties of soils and more significantly in the case of soils having larger sand fractions. A series of simple tension tests was additionally conducted to clarify the reinforcing mechanism more in detail for the purpose to apply the soil stabilization technique for reinforcement of soil structures and effective utilization of surplus soils. It was observed that the tensile failure was very progressive. The bending and tension strength characteristics were obtained to establish the design model for the member in bending mode.
