A Methodology of Waste Material Utilization in Concrete Mix for Rigid Pavement Construction

Abstract

Abstract: The demand of concrete for rigid pavement construction is constantly growing. Thus, the extraction of fine aggregate, coarse aggregate and cement from natural resources also increases. The more extraction of these virgin materials from the natural resources enhances the cost of these materials progressively. Therefore, it has severely affected the financial viability of the government for rigid pavement construction. Further, due to urbanization and industrialization the amount of waste material is also increased. This state creating an ecological problem that must be addressed. Therefore, there is an urgent need to preserve natural resources by using recycled or discarded wastes as a construction material. Hence the main objective of this work is to study of utilization of waste material in concrete production for rigid pavement construction. A four stages methodology is proposed in this study. these stages are (I) Determination of quantity of various materials for development of concrete mix (II) Identification of significant waste materials and their properties (III) Prepare concrete mix using replacement of cement, sand, and aggregate by waste material and (IV) Comparative evaluation of different properties of developed concrete mix. This study to check the suitability of waste foundry sand (WFS), granulated blast furnace slag (GBFS), and waste rubber tyre (WRT) as a replacement of fine aggregate, cement, and coarse aggregate respectively. The analysis and results indicated that WFS, GBFS, and WRT can be used as a replacement of fine aggregate, cement, and coarse aggregate respectively. Thus, it is expected that the proposed methodology will be useful for researcher to determination of suitability of different alternative materials for replacement of cement, fine aggregate, and coarse aggregate Keywords: Concrete mix, Waste Material, GGBS, WFS, WRT etc.
