Effect of Coconut Fiber and Nano Silica on Compressive Strength of Concrete

Natural aggregate and cement are the basic elements of concrete. Due to exploding world population, construction activities are growing by leaps and bounds, leading to a whole new jungle of concrete, thus enhancing the requirement of the natural aggregate cement. This research is the investigation for examining the effect of nano silica and coconut fiber on compressive strength of concrete. For completing the objective of the study, Coconut fiber has been added in the concrete with the variation of 0.25 %, 0.5 %,and 0.75 % by the weight of the fine aggregates and 2 % and 3 % nano silica and 20 %fly ash have partially replaced cement in the mix. Fly ash is a waste material which is generated by burning of coal in power plant. Different samples with varying percentages of nano silica and coconut fiber have been prepared keeping water to binder ratios as 0.47, 0.45 and 0.42 for calculating the compressive strength results have been compared with the controlled specimens.
