Abstract

Portland Cement Pervious Concrete (PCPC) is a special high porosity concrete containing zero or minimal amount of fine aggregates. Such concrete endows the concrete to have significant voids allowing water to percolate; however, such an open void structure reduces the mechanical strength of the concrete considerably. It is recommended that chemical admixtures be added to the concrete to enhance its workability and other properties. The study aims to potentially enhance the properties of PCPC through the incorporation of various fiber reinforcement schemes. The fibers used in the scope of this study are hooked-end steel fiber, macro-polypropylene fiber, and glass fiber. To meet that objective, concrete mixes were prepared using varying fiber dosage rates and aggregate gradations. An experimental program was developed to test fresh concrete properties, hardened concrete properties, and durability. In order to gauge only the effectiveness of the aforementioned fiber, the PCPC mix design was standardized across the spectrum to eliminate such variables. It was evident that the glass fiber with Vf 0.17% (GF 2) enhanced mechanical properties with the most significant compressive strength increase, compared to the control sample, reaching 34 MPa. Moreover, (GF 2) has enhanced, compared to the control sample, the flexural and the splitting tensile strength with an increase of 93.7% and 161.9%, respectively. The outcome of the study is that the use of different fiber reinforcement schemes has managed to enhance the mechanical strength of PCPC while maintaining an adequate rate of infiltration that complies with ASTM standards. The research opens the door for further application of the proposed model in different contexts both regionally and internationally, thus playing a vital role in the concrete nexus.
