Recycling of disposal Polypropylene Blister Tablets and Strapping ties as fiber reinforcement for Pervious concrete

Abstract

Pervious concrete (PC) was introduced as a solution for the runoff from rainfall. To insure high porosity, pervious concrete should contain limited quantities of fine aggregate, which adversely effects concrete mechanical properties. As an attempt to improve PC mechanical properties, fibers were added to concrete matrix. As PC is allows water to pass through it, metal fibers are uncourageous to be added to it. Plastic fibers were selected as an alternative to metal fibers to be added to PC. Concrete physical and mechanical properties were studied for mixtures containing different quantities of fibers. Tests results showed a slight improvement in concrete compressive strength (0.48% to 1.44%) as fibers were added. The addition of fibers improved splitting tensile strength by (6.36% to 27.67%). As adding fibers, concrete flexural strength increased by (11.37% to 24.17%) compared to the reference mixtures. of PC. Concrete physical properties (Density, Porosity and permeability) were also investigated. The addition of fibers to concrete has a slight effect on (density, porosity and permeability).
