Abstract

Increasing infrastructural needs have been creating huge stress on available natural resources leading to environmental deterioration. In a developing nation like India, concrete is a commonly adopted material in major infrastructure projects. Environmental burdens associated with the manufacture and processing of raw materials for concrete are enormous. The major impact associated with concrete production is carbon dioxide gas emission during cement manufacturing and the depletion of natural resources for aggregate production. These environmental issues have paved the way for adopting eco-friendly materials and techniques in concrete production. Industrial by-products such as fly ash, blast furnace slag, silica fume, etc., are successfully employed as cement replacements for sustainable concrete production. The present research has been aimed at examining the potential of phosphogypsum, the by-product of the fertilizer industry, as a partial replacement of cement (5, 10, 15 and 20%). The compatibility of phosphogypsum with cement has been initially studied and adopted for the production of M20 concrete. The performance of the processed concrete was analyzed in terms of workability and mechanical properties. Results obtained have proved the potential of phosphogypsum for adaptation as a retarder in concrete production; the optimum replacement was found to be only up to 10%. For enhancing the properties of the concrete, the study has been extended with partial replacement of glass fiber (0.5%, 1%, 1.5% and 2%) for M20 concrete with phosphogypsum content (5% and 10%) of cement replacement. Obtained results have suggested the suitability of utilizing these nanomaterials (with 1.5% glass fiber and 10% phosphogypsum) for M20 concrete.
