Experimental Study on Strength of Concrete by Partial Replacement of Cement by Cashew Nut Shell Ash (CNSA) and Chicken Feather Fiber (CFF) as Fiber Reinforcement

In this project, to reduce the cement content in the concrete to use the cashew net shell ash (CNSA). Most ashes have pozzolanic activity and may be used as a cement replacement material, resulting in less energy waste and low-cost composite. And also increase the strength of concrete to add the chicken feathers as a fiber. The CFF has the presence of more void space in its cross-section, so it has good resilient property. By using the CFF will save cost, eco-friendly environment and also help the fiber industry sustainable. Combination of CNSA and CFF is cost-efficient and improve the strength of the concrete block.
