Concrete is being widely used in all infrastructures and its material is mainly very expensive for the construction. The Bamboo sticks are unutilized in the concrete work and hence their usage may help to decrease the cost of construction. The use of waste materials in concrete production is becoming worldwide practice. The assessment of the activity of cement materials is becoming increasingly important because of the need for more sustainable cementing product. The early work has been carried out with partial replacement of Bamboo leaf ash with cement in order to increase the tensile strength of concrete and compressive strength has been decreased. Now we are using partial replacement of stick ash with cement in order to increase the compressive strength of concrete. The use of Bamboo stick and leaf ash with the partial replacement of cement is used in the concrete in order to know the compressive strength and tensile strength. Compressive strength of 28 days curing with partial replacement of BSA to cement gives 25 N /mm2 at 5% of ash replacement and it is observed that 20% of strength is decreased than conventional concrete. Compressive strength of 28 days curing with partial replacement of BLA to cement gives 26.20 N /mm2 at 10% of ash replacement and it is observed that 17% of strength is decreased than conventional concrete. Tensile strength of 28 days curing with partial replacement of BSA to cement gives 2.65 N/mm2 at 5% ash replacement and it is observed that 44% of strength is decreased than conventional concrete.

Tensile strength of 28 days curing with partial replacement of BSA to cement gives 2.65 N/mm2 at 10% ash replacement and it is observed that 44% of strength is decreased than conventional concrete. The partial replacement is done with the following percentages of 0, 5, 10, 15 with Bamboo stick and leaf ash separately. Thus, from the results obtained, it can be concluded that use of bla as a supplimentory for cement gives good result.
