Geotechnical Characterization Cement - Fly Ash –fibers Mix

The fly ash is a waste produced mostly from the burning of coal in thermal power station which contributes to environmental pollution. It is naturally-cementitious coal combustion by-product. Many studies have been reported in the literature on the performance evaluation of soil – fly ash system as well soil-fly ashfiber system. Although ample studies have been reported with randomly distributed fibers, relatively less amount of work is found in respect of polypropylene fibers and cement. In view of this, an experimental investigation being undertaken for the performance evaluation of polypropylene fiber-cement-fly ash system is proposed to be reported in Dissertation report. The objective of present investigation is to quantify the optimum quantity of randomly distributed fibers and cement on the performance in terms of unconfined compressive strength especially when it is planned to be used as sub base for foundation and also in highways The results obtained so far reveals that there is significant improvement in the compressive strength with inclusion of randomly distributed fibers. Further it is observed that the optimum moisture content increases and maximum dry density decreases with increase in percentage of polypropylene fibers with stabilized Fly ash.
