Abstract

In addition to the economic advantages, using fly ash in cement has enormous effect on the mechanical properties of the concrete. Moreover, Researchers have identified that the addition of fibers to concrete increases its mechanical properties. Therefore, Better concrete product using both fly ash and fibers especially natural fibers which are more economical and eco-friendlier than the other fibers for an improved concrete strength production is the major aim of this research. This experimental investigation had been undertaken to study a fly ash concrete reinforced with bamboo fibers. The optimum percentage of fly ash to replace cement was first determined by compressive strength test for different percentages by weight of fly ash substitution. After that, mechanical properties of the fly ash concrete were studied with the addition of three different percentages of bamboo fibers. Mix designs were formulated for all percentage and then, Specimens were casted and tested for computing compressive strengths, indirect tensile strengths and flexural strengths for 7^th and 28^th day period. In the experiments, non-fibrous 25% fly ash substituted with cement concrete (the optimum percentage which was first determined using compressive strength) were compared with the 25% flyash substituted with cement for the individual fibers percentages. The standard 150mm cube compressive strength of bamboo fiber reinforced Fly Ash Concrete (BFRFAC) with 0.10% addition of bamboo fiber by weight of concrete showed an increment of 12.44%, Whereas bamboo fiber reinforced Fly Ash Concrete with 0.2% and 0.30% addition of bamboo fiber by weight of concrete showed a compressive strength reduction of 9.33% and 33.03% respectively compared to non-fibrous fly ash concrete. Bamboo fiber reinforced Fly Ash Concrete with 0.10% and 0.20% bamboo fiber addition by weight of concrete showed an increment in mean split tensile strength of 5.81% and 0.12% respectively; whereas 0.30% additions of bamboo fiber by weight of concrete showed split tensile strength reduction of 14.54% compared to non-fibrous fly ash concrete. Mean Flexural strength of bamboo fiber reinforced Fly Ash Concrete with 0.10%, 0.20% and 0.30% addition of bamboo fiber by weight of concrete showed an increment by 2.48%, 5.98% and 7.80% compared to non-fibrous fly ash concrete respectively.
