Experimental study on the strength parameters of self compacting concrete reinforced with carbon fibre

Abstract

Concrete being the most used material in construction, resulting to an increase in carbon footprint at a global rate. This results to the increasing search of sustainable concrete as a construction materials and Self compacting concrete (SCC) is one such example. Self-Compacting Concrete (SCC) is a special type of concrete that does not require any kind of compaction or vibration wherein flows under its own weight. This type of concrete can flow easily around the reinforced areas and into all over the formwork economically reducing the time for other works, labour and energy. Many studies had been carried so as to know the effectiveness of carbon fibres (CF’s) on the various properties of concrete. Addition of carbon fibres to concrete may offer significant improvements to the concrete’s fresh and hardened properties such as filing ability, passing ability, compressive strength, flexural strength etc. CFs are being attractive due to their thermal conductivity and low density. In this paper, the fresh and hardened properties of SCC were carried out by the following tests like V-Funnel test, Slump flow test etc. for the fresh properties and test for compressive strength and flexural tests were carried out. Chopped carbon fibres were added to the SCC in different percentages of 0.1%, 0.15% and 0.20% respectively and studied the optimum percentage of addition in acquiring the results. Optimum percentage for addition of CF to SCC was found at 0.15%.
