Studies on Mechanical Behaviour of Basalt Fibre Reinforced Cement Concrete

One of the primary goals of concrete engineering is to increase the material’s strength. High-strength concrete (HSC) has been gaining popularity among structural and civil engineers in recent years. Exhibiting a life cycle cost-performance ratio surpassing that of conventional normal-strength concrete (NSC), it also boasts unparalleled compressive and tensile strengths, stiffness, and durability. Furthermore, it surpasses the NSC in regards to the ratio of cost-performance throughout its life cycle. To ascribe the burgeoning favourability of high-strength concrete, one must acknowledge its manifold applications within the realm of the construction industry. So in this research work, the performance of high-strength concrete (HSC) is evaluated by adding different proportions of basalt fibre and alccofine. It was found that the addition of basalt fibre by 1.5% and alcofine by 20% in concrete resulted in an increase in compressive strength of 8.9% for 7 days and 4.9% for 28 days; similarly, split tensile strength increased by 30% and 31.31% for 7 days and 28 days, respectively. The flexural strength is also increased by 28.26% and 22.30% for 7-days and 28-days cured specimens, respectively.
