A Demand of concrete materials in Civil Engineering applications finds a wide variety of works in construction aspects. But the rising cost of construction materials is a matter of concern. Certainly, there is a crucial need to search for an alternative solution. The selection of materials should not endanger the environment with its bio-reserves. Such materials should be of cost effective. In this pilot study, partially replacing aggregates in concrete using bamboo and coconut Fibres seems to be an effective alternative way. These fibres are cheap, renewable, flexible and more resistant to thermal conductivity. All cubes, beams and cylinders are casted with traditional methods and later the same are casted by replacing coarse and fine aggregate with 4 % and 6% of bamboo and coconut fibre. 36 specimens are casted and their compressive, split-tensile and flexural strength were evaluated at 7 days (compressive only) and 28 days. The behaviors of the specimens have been studied and results are compared with conventional specimens.
