Abstract. While porous concrete has a poor compressive strength because of its porous structure, concrete will lead to failure when the load applied is high. With recycled concrete aggregate and PVA fibre, an attempt was made to improve porous concrete’s physical and mechanical properties. The features of ingredients such as recycled concrete aggregate, cement, Polyvinyl alcohol fibre, and water were first discovered, and then the mix was created and cast. After proper curing, the mechanical properties of concrete were determined by conducting the following tests: compression strength, split tensile strength, and flexural strength, along with physical factors such as permeability. The findings reveal that using the aggregate size of 1012mm improves mechanical characteristics. Permeability was also excellent. On the other hand, strength increased as the percentage of PVA fibre grew and at a certain point strength as well as porosity decreased. The maximum strength was attained at an incorporation % of 1. The mechanical characteristics of the aggregate declined when the size increased, as the surface area available for the cement to bind them together shrank.
