Abstract

This Experimental work shows the investigation on M30 grade due to incorporation of glass fibers. In this Experiment, we used the glass fibers of Filament diameter 14 microns with aspect ratio 857.1 at various percentages as 0 , 0.4 , 0.8 , 1.2 , 1.6 by the weight of cement on M30 grade of mix proportion 1 1.60 2.96 with water cement ratio 0.45. Hence, in this research the Experimental investigations and analysis of results were conducted to study the compressive, tensile and flexural behavior of composite concrete with varying percentage of such fibers added to it. The concrete mix adopted were M30 with varying percentage of fibers ranging from 0, 0.4, 0.8, 1.2 and 1.6 by weight of cement. On the analysis of test results, the concrete with straight glass fibers had improved performance as compared to the conventional concrete, which was readily available in market. From the experimental investigation, It has been found that optimum dosage amount of glass fiber of concrete is 1.2 by weight of concrete because at this point the compressive strength of GFRC increased up to 17.36 as compared to plain concrete while the flexural Strength increased up to 35 and Split Tensile Strength increased up to 40 . The common person in their regular constructions could easily adopt these sustainable improvements or modifications. Manoj Kumar | Er. Shashi Sharma | Er.
