Experimental Investigation on Bamboo-Made Cellular Mattress Reinforced Fly Ash Beds Overlying Soft Clay
The present study encompassed laboratory model tests on cellular mattress reinforced fly ash beds overlying soft clay. A series of model tests were performed to analyze the influence of mattress width on the overall performance of the system in terms of footing pressure applied over the center of the beds by means of a square rigid steel plate, footing settlement and the adjacent surface deformation (heave/settlement). The study was subjected to the limitation of scale and boundary effects. Laboratory test results indicated around two folds increment in footing capacity for a jute geotextile separator underneath the unreinforced fly ash bed, while around a five-fold increment in capacity was achieved for the cellular mattress reinforced fly ash bed along with the separator. The surrounding surface deformation of the loaded area over reinforced fly ash bed got diminished with an increase in the width of the cellular mattress, while the footing capacity kept on improving. The cellular mattress along with jute separator with basal bamboo grid produced optimum performance. Despite scale and boundary effects, the qualitative results from the present study encourage the use of bamboo-made cellular mattresses for soft ground improvement, while it contributes to the solution for disposal of fly ash. Again, bamboo is a very fast-growing tree and abundantly available in India and other Asian countries. The present study advocates a sustainable, cost-effective, harmless to environment and energy-efficient approach for infrastructure development.
