FEASIBILITY STUDY OF BAMBOO ASH ON CONCRETE MEMBERS
Abstract
- This study investigates the strength performance of concrete using partial blends of cement and bamboo ash. The bamboos were dried under sunlight and burnt in air. Bamboo ash was obtained after passing the residual through 200μm sieve. Elemental analysis was conducted on bamboo ash and ordinary portland cement, OPC by EDXRF (Energy Dispersive X-ray Fluorescence) technique to evaluate its percentage composition. Bamboo ash shows pozzolanic activity and it was used as supplementary cementitious material. Bamboo ash was then used to replace OPC by weight in ratio of 0%, 5%, 10%, 15%, 20% and 25% in concrete (M-15 & M-20). Base upon the quantities of ingredients of the mixes (1:2:4), M-15 grade and mixes (1:1.5:3), M-20 grade concretes were prepared. Twelve pieces of 150 mm concrete cubes were prepared. These cubes were tested at 28 days of curing ages and then maximum load and compressive strength of cubes were determined respectively. To investigate the pozzolanic behavior of bambo ash , (95%OPC+5% bamboo ash) and (90% OPC+10% bamboo ash) concrete crushes were analyzed by XRD analysis.
