Abstract

Concrete's resistance to weathering, chemical assault, and other deterioration processes is referred to as durability. The effects of acid, sulphate, and chloride attacks on the calibre and practicality of concrete are also discussed. In order to report on the longevity of synthetic fibres like aramid fibre, an experimental examination was carried out. This article examined the impact of aramid fibre on the durability of concrete for M30 grade by altering the proportion of aramid fibres in concrete. Aramid fibre reinforced concrete samples were subjected to tests for water absorption, sorptivity, RCPT, and chemical resistance (acid, sulphate, and salt). After 28 days of curing, the test samples' tensile strength was assessed. In the experiment, fibre dosages of 0.5%, 1.0%, and 1.5% by volume of concrete were employed for a length of 2.5 cm or less. By submerging these cubes for 30 days in the aforementioned solutions and observing the corresponding changes in compressive strength and weight reduction, we were able to determine the effects of 5% H2SO4, HCl, MgSO4, and NaCl on these concrete mixes. From this, we were able to draw the conclusion that aramid fibre reinforced concrete had better strength and durability properties than conventional aggregate in harsh environments. The experimental investigation's findings indicate that aramid fibre reinforced concrete has higher durable qualities than ordinary cement concrete.
