Study of Sustainable Pervious Concrete using Agro- Industrial Waste

For the effective synthesis of sustainable pervious concrete, the polycarboxylate ether-based superplasticizer is blended together with agro-industrial waste materials, in which iron slag and rice husk-activated carbon are specifically utilized as partial replacement materials in order to provide workability at lower water/cement ratios. The aim and objective of this research are the enhancement and development of improved mechanical and durable qualities and reducing the environmental concern related to concrete production by synthesizing and implementing waste-produced components. Comprehensive analysis (specific gravity, abrasion resistance, crushing strength, XRF analysis, SEM-EDS, and XRD analysis) confirmed that iron slag is useful as a strong and angular aggregate that could hold reactive mineral constituents such as gehlenite and akermanite. High pozzolanic activity is also evident in RHAC, which contains high silica proportions and is known as an amorphous material that is macroscopically very porous. Based on these characteristics, mix designs are conducted in order to evaluate effective improvements in structural density development, strength, and permeability. The experimental findings confirmed that proper mix proportions of iron slag and RHAC could allow effective improvements in load transfer efficiency and afford greater development in the amount of C-S-H, which could afford reduced waste disposal problems and could also reduce dependence on natural aggregates. Based on these experimental findings, the research illustrates that agro-industrial wastes are an effective solution that could afford the development of environmentally compatible pervious concrete incorporating advanced chemical admixtures that could afford more functional qualities.
