Analysis Of Pervious Concrete With Waste Marble Powder Blended Cement And Recycled Pet Fibers As A Sustainable Construction Material

Abstract

Pervious The Rapid Pace Of Urbanization Has Significantly Increased Impermeable Surface Areas, Leading To Severe Storm Water Runoff And Depleting Groundwater Reserves. Pervious Concrete Offers A Viable Solution For Sustainable Storm Water Management; However, Its Widespread Structural Application Is Often Hindered By Inherently Low Tensile Strength And Brittleness. This Study Investigates A Cleaner Production Approach By Evaluating The Mechanical And Hydrological Performance Of Eco-friendly Pervious Concrete Incorporating Two Distinct Industrial And Municipal Waste Streams: Waste Marble Powder (WMP) And Recycled Polyethylene Terephthalate (PET) Fibers. In This Investigation, WMP Was Used As A Partial Replacement For Ordinary Portland Cement (OPC) At Varying Percentages, While Recycled PET Bottles Were Processed Into Fibers And Introduced As Discrete Reinforcement. A Comprehensive Laboratory Program Was Executed To Analyze The Fresh And Hardened Properties Of The Modified Mixes. The Hydrological Performance Was Assessed Through Total Porosity And Falling-head Permeability Tests, While The Mechanical Behavior Was Evaluated Via Compressive Strength, Split Tensile Strength, And Flexural Strength Testing. The Results Indicate That While PET Fibers Bridge Micro-cracks And Substantially Enhance The Tensile And Flexural Capacity Of The Porous Matrix, The Extreme Fineness Of WMP Acts As A Micro-filler, Densifying The Interfacial Transition Zone Around The Smooth Plastic Fibers. This Synergistic Interaction Helps Mitigate The Typical Strength Loss Associated With Plastic Inclusions Without Significantly Compromising The Required Hydraulic Conductivity. The Findings Demonstrate That Optimizing WMP And PET Fiber Content Yields A Highly Sustainable Construction Material Suitable For Low-volume Traffic Pavements, Pedestrian Walkways, And Parking Lots
