An Experimental Study on Fresh and Hardened Concrete Using Coconut Fibre as a Partial Replacement of Cement

Abstract

In today’s scenario,sustainability may be a widely accepted concept. Despite the reality that the building industry is revolutionising in terms of both technology and products used, the expense of construction has increased day by day, resulting in a detrimental effect on the environment. As a result, a more balanced approach was introduced, with the environment as its nerve core, to create a much healthier universe to calculate in. As a result, a fibre like coconut has been used to increase the resilience of concrete.

Coconut fibre is readily accessible at the test site, making it a feasible alternative for concrete strengthening. It also offers a new source of income for coconut farmers, who can be benefited from the construction industry's increased demand. Furthermore, it is a cost-effective coir mattress waste disposal system that decreases the need for new waste disposal facilities while also reducing the burden on existing landfills and incinerators. The problem of the fibres absorbing a lot of water may be fixed by covering them with oil.

Coconut fibre reinforced concrete with varying percentages (4%, 5%, and 6% by the weight of cement) anda water cement ratio of 0.5. In this analysis, we find that the conventional compressive strength of concrete and coconut fibre reinforced concrete after 7 days and 28 days. By this study, we can analyse the compressive strength of concrete of coconut fibre reinforced concrete and compared the result with the conventional strength of concrete and we find that the compressive strength of coconut fibre reinforced concrete is better.
