Properties of sand-self cementing flyash mixtures

The Class C fly ash which is an industrial by-product of coal combustion in electric power plants has cementing characteristics which can be utilized for the stabilization of soils. Laboratory investigation was done to analyze and determine the behavior, engineering properties of the sand-class C fly ash mixtures. Several samples of this mixture were prepared with desired mix proportions and triaxial, California Bearing Ratio (CBR) tests were performed. The test results were used to evaluate the effectiveness of this mixture as a pavement base course. An illustrative low volume road design incorporating fly ash stabilized soil as its base course is shown. Also a model of pile foundations in the stabilized soil was built in the laboratory and compression testing was performed on these piles until failure to understand the nature of load deflection curves and to determine the load carrying capacity.;This abstract of 142 words is approved as to form and content.
