| Abstract | The use of pervious concrete to reduce the effects of soil impermeability as a result of increased urbanization is a viable option that still requires more research and development in terms of design and implementation. In this light, the focus of this research is on the properties of pervious concrete, such as compressive strength, void content, and water infiltration in the field, as well as the development of various combinations to change the features of the local aggregates. Three types of combinations were tested, one of which was similar to pervious concrete without finer aggregate. Following that, two combinations of shredded polyethylene terephthalate (PET) and polypropylene (PP) were investigated to see how the addition of recycled plastic affected the qualities of pervious concrete. The inclusion of shredded plastic of various sizes modified the features of the concrete, boosting its strengths while maintaining a reasonable penetration rate, according to the findings. There was an increase in the compressive strength of the pervious concrete, which is the most important attribute to consider for its use in pavements, without compromising its permeability, which expands its application possibilities. In this experiment the no fine aggregate (sand) was used and cement and coarse aggregate (local stone) ratio was maintained approximately 1:3, where the gradation of the coarse aggregate is 12 mm to 20 mm. The cement-water ratio was .33, whereas mixed recycled plastic ratio was upto 20% of the volume of coarse aggregate. The shredded Polyethylene terephthalate (PET) chips were smaller that the Polypropylene (PP) and the blocks that contained smaller chips showed increase in the compressive strength of the recycled plastic pervious concrete blocks than regular pervious concrete blocks with the same cement, aggregate and water ratio. |
