EXPERIMENTAL STUDY ON PARTIAL REPLACEMENT OF COARSE AGGREGATE BY BAMBOO AND FINE AGGREGATE BY QUARRY DUST IN CONCRETE

Concrete is the most used construction material across the world and in concrete maximum part is fine aggregate. Naturally available river sand is the commonly used as a fine aggregate in many countries. The more requirement for concrete has made this natural rive sand resource to get weakens. On one side the depletion of river sand in excess has shows very clear environmental impacts, on the other side, production of very huge amount of quarry dust is being produced during the process of quarrying and its leading to many environmental problems. It is necessary to carry out the research on identifying the feasibility of using alternative waste materials like bamboo and quarry dust. In this study, the laboratory investigation carried out on strength characteristics of bamboo and quarry dust on M40 concrete. The percentage of bamboo added by volume basis was 0, 5%, 10%, 15%, 20%, and 25% as replacement of coarse aggregate used in concrete. From the result it is concluded that 15 % of bamboo replacement in concrete shows good results on compressive strength, flexural strength, split tensile strength and durability characteristic compare to control concrete. Similarly the percentage of quarry dust added by weight was 0, 15%, 20% and 25%, respectively the fine aggregate replacement in concrete. From this experimental results it is observed that replacing coarse aggregate with 15% of Bamboo and fine aggregate by15 % of Quarry dust gave a satisfactory result when compared with conventional concrete for 7 days and 28 days. Hence the use of Bamboo and quarry dust as replacement for coarse aggregate and fine aggregate in concrete is reducing the Environmental wastes which pose a difficult problem in its disposal.
