摘要

Stone dust is rock particles formed when huge rocks are broken into smaller sizes for use as construction material. Enormous amount of stone dust is generated as waste product at quarry sites all over India. Proper utilization of this waste is needed in a developing country like India. To check the suitability of this waste product in geotechnical engineering applications, a series of triaxial tests have been performed on stone dust without and with reinforcement. Reinforcements used were bamboo grid (BG) and steel grid (SG). Circular reinforcement grids of diameter 55 mm were used and placed in the triaxial specimen in four different arrangements as: one layer at center, two layers each at 1/3~(rd) height, three layers each at 1/4~(th) height, and two layers with one each at top and bottom of specimen. For all cases, BG reinforced specimen corresponded to higher peak deviator stress and shear strength parameters compared to that with SG. Finite element simulation is carried out with Plaxis 2D software, the results obtained show good agreement with the experimental results.
