Flexural Behaviour of High Performance Reinforced Concrete Beams Using Industrial Byproducts
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 1
Abstract
In this study experimental investigations were carried out to explore the possibility of using Fly Ash, silica fume and metakaol in as a replacement of cement and bottom ash as a replacement of sand to make high performance concrete mixtures. The main objective of this study is to evaluate the flexural strength of high performance concrete beams by utilizing fly ash, silica fume, metakaolin and bottom ash. A total of eight rectangular beams were cast and tested. The beams were 125 mm 250 mm in cross-section and 3200 mm long. The beams were tested in two point loading over a simply supported span of 3000 mm. Of the above eight beams, 2 beams served as control specimen, 6 beams were cast with three different combinations of replacement of cement and fine aggregate. All the beams were evaluated in terms of load, deflection, moment, curvature and ductility. The test results indicated that beam with cement replacement by 10% silicafume and 10% metakaolin and fine aggregate replacement by 20% bottom ash exhibit 60% increase in load carrying capacity when compared to that of control beam.
