CHARACTERISTICS OF FIBRE-REINFORCED COCONUT SHELL AGGREGATE CONCRETE

In this experiment, sisal fiber is used as a reinforcement in a coconut shell aggregate concrete. This is one of the experiments to check if coconut shell as an aggregate is suitable for a lightweight concrete. The sisal fiber was applied in the ratio of 0, 0.15, 0.3 & 0.5% to improve the mechanical and physical properties like the compressive strength, flexural strength, split tensile strength and its structural integrity. The construction industry views coconut shell concrete containing sisal fiber as an appropriate and environmentally beneficial substitute for conventional building materials. According to the test results, Coconut shell aggregate concrete durability qualities are on par with those of other traditional lightweight concretes, and convenient curing is required for Coconut shell aggregate concrete to reach higher durability. Additionally, it shows that coconut shell can be utilised to make lightweight concrete for non- structural elements, strip footings, and non-load bearing buildings. By using these leftover coconut shell components, sustainable and effective procedures can also reduce environmental problems. The features of fiber-reinforced coconut shell aggregate concrete (FRCSC) with different fibre contents (0.15%, 0.3%, and 0.5% by volume) are examined in this study. The effects of fibre composition on durability, tensile strength, and compressive strength are investigated. When compared to the control mix, the results demonstrate that FRCSC with a 0.3% fibre content has the best mechanical qualities, with notable gains in compressive and tensile strength. According to the results, 0.3% fiber-reinforced cement (FRCSC) is a potential material for environmentally friendly building that offers improved performance. Compressive strength, splitting tensile strength, and flexural strength are tested experimentally at 3, 7, 21, and 28 days of cure. According to the findings, adding sisal fibre improves the concrete's tensile and flexural qualities; the best results are obtained when the fibre level is 0.3%. Sisal fibre has the potential to improve structural performance in lightweight concrete, as evidenced by its better post-cracking behaviour and energy absorption capacity, even if compressive strength marginally declines as fibre concentration increases. This study promotes the use of sustainable agricultural byproducts in building, which helps to preserve the environment and enhance the performance of Materials
