Influence of Treated and Untreated Bamboo Fiberson Properties of Concrete

Abstract

This research paper studies the effects of bamboo fiber, treated with sodium carbonate and hydrogen peroxide combined with glacial acetic acid, on the characteristics of concrete. The study examined mechanical propertiessuch as compressive strength, split tensile strength, flexural strength, and durability of concrete incorporating bamboo fibers. Bamboo fibers, both treated and untreated, were used, measuring 24 mm in length, 5 mm in width, and 3 mm in thickness. The research investigated the impact of adding 1% and 1.5% bamboo fiber to concrete's mechanical properties and durability, using M40 grade concrete as the baseline. Evaluations were carried out at 7 and 28 days. The study compared standard concrete with bamboo fiber-reinforced concrete. Results showed that the compressive strength of concrete increased with the use of treated bamboo fibers. Adding 1% bamboo fiber improved both split tensile and flexural strength. However, increasing the bamboo fiber content beyond 1% generally led to a reduction in these properties. The highest compressive strengths recorded were 47.2 N/mm² for 1.5% bamboo fiber treated with sodium carbonate and 48.1 N/mm² for 1% bamboo fiber treated with hydrogen peroxide and glacial acetic acid. Overall, concrete with 1% bamboo fiber exhibited the best performance.
