Strength and Durability Performance of Basalt Fibre Reinforced Concrete Made with Concrete Debris and GGBFS

Concrete is one of the versatile construction materials which has the significant property of high compressive strength under varying exposure conditions. Over the past century, there are numerous constructions were done with the help of concrete and steel around the world. Utilization of concrete in the field of construction, increases the consumption of raw materials like cement and aggregates which could results in shortage of raw materials and produces numerous socio-environmental problems. In this study, it is suggested to utilize some of the industrial wastes as a substitute for the raw ingredients of concrete. It is essential to determine the strength and durability performance of a concrete over a long period of time, because it is necessary to analyse the performance of concrete whenever a substitution is made on the ingredients of concrete. In this article, M30 grade basalt fibre reinforced concrete (BFRC) was made with 0%, 0.3%, 0.6% and 0.9% of basalt fibre by volume of concrete, over the mean time cement was replaced with 30% ground granulated blast furnace slag (GGBFS) and coarse aggregate was replaced by demolished concrete debris (DCD) from 0% to 100% at an interval of 20%. To predict the performance of BFRC, strength and durability properties were assessed at varying curing periods from 28, 56 and 90 days. Various tests were performed on strength properties (Compression, Split tensile and Modulus of Rupture) and durability properties (Carbonation test, abrasion resistance, water and chloride penetration test).
