Abstract
Concrete with fiber as a reinforcing material is one of the important fields of research that is gaining traction in this upcoming green technology revolution. By adding fibers to concrete, the tensile strength properties are vastly improved without compromising the strength characteristics, and cost fluctuation is minimal. This research is being carried out to improve the qualities of concrete that have been infused with chemically treated sisal fiber in varied ratios. The paper investigates and describes the effects of sisal fiber when it is chemically treated and infused with concrete, comparing it to ordinary concrete in strength tests. Water absorption, workability, and other material characteristics of Sisal fiber reinforced concrete with 0.5 per cent, 1 per cent, 1.5 per cent, and 2 per cent fiber replacing cement by volume fraction and a sisal fiber aspect ratio of 1:100 are compared to the traditional M30 concrete grade. After being treated with an alkaline solution, 0.5 per cent and 1 per cent sisal fiber reinforced concrete increased tensile and compressive strength, as well as the formation of calcium carbonate deposits on the fiber interfaces; this also contributes to the concrete’s corrosion resistance and durability.

Summary
Natural fibers are biodegradable and are extensively being used in new generation concrete technologies. There is a conclusive result of all the experiments stating that adding natural fibers such as sisal, coir, hemp, Kenaf, pineapple fiber will be used as reinforcement and will provide better strength qualities (Jitendra et al 2016). They provide better insulation against electrical and thermal objects and have acoustic effects (Wei & Meyer 2014). Sisal fiber is high in tension and low in density, many studies were conducted to understand its effectiveness and its application in concrete structural material (Abirami et al 2020).
