Abstract: The urgent need to reduce the environmental footprint of the construction industry, where cement production contributes significantly to global co2 emissions motivates the search for sustainable alternatives. This study evaluates the potential of bamboo fibers and fly ash as eco-friendly substitutes in concrete production. Bamboo fibers were incorporated as a fine aggregate replacement, while fly ash partially substituted cement to mitigate environmental impacts. A series of 45 cylindrical specimens were cast with varying proportions of bamboo (2%, 4%, 6% and 8%) and fly ash (5%, 10%, 15% and 20%), and compressive strength tests were conducted at 7, 14 and 28 days of curing. The results indicate that an optimal mix, containing4% bamboo fibers and 15% fly ash, balances mechanical performance with sustainability objectives. Although increased bamboo content slightly reduced workability, fly ash contributed to long-term strength gain through its pozzolanic activity. This research provides valuable insights into the design of sustainable concrete mixes that reduce cement consumption and lower carbon emissions. Future investigations should address durability aspects and large-scale application feasibility to further advance eco-friendly construction practices.
