Enhancing Pervious Concrete for Pavements: The Impact of Mineral Admixtures

Abstract

The fundamental difficulty provided by impermeable pavements is inadequate surface runoff drainage, which causes degradation of the wearing course and contributes to the urban heat island effect. Nonetheless, pervious concrete offers a possible answer to
this problem. Pervious concrete is useful in parking lots and sidewalks, and it may be used with geo-synthetics to counteract coastal erosion. Pervious concrete's efficiency is determined by a number of elements, including pore structure, cement matrix,
aggregate gradation, cement concentration, admixtures, and water/cement ratio. This research focuses on three important elements of pervious concrete. To begin, it seeks to create an optimum combination with high compressive strength and permeability, finding a balance to assure durability and efficiency across a wide range of applications.
Secondly, durability tests are being conducted to assess the material's long-term performance under diverse environmental conditions and stress factors. Lastly, the study explores the impact of mineral admixtures on pervious concrete's strength and durability, potentially leading to the development of improved mixtures. Through these research objectives, the study aims to enhance the understanding and application of pervious concrete, addressing the challenges associated with impervious pavements, managing surface runoff effectively, and mitigating the urban heat island effect. Additionally, it advocates for sustainable construction practices that prioritize environmental conservation without compromising structural integrity.
