| description | Increasing urbanization and industrialization leads to excessive use of natural resources such as
river sand and gravels, storage and disposal methods of wastes in sanitary landfills create great
economic obligations and increase environmental concerns. Therefore, managing solid waste byproducts and materials by repositioning has become an attractive alternative form of disposal. In this study, the effects of the use of waste foundry sands (WFS), which is an industrial waste type, by substituting natural fine aggregates in geopolymer concrete (GPC) were investigated. As a result of the investigations, it has been determined that there are a limited number of studies in the literature on the use of WFS as a substitute for natural sand in various industrial waste-based GPCs. In these studies, it was revealed that the focus was mostly on mechanical properties and the compressive strength among mechanical properties was examined more. In addition, it was observed that different WFS optimum substitution rates were determined in determining the compressive strength of WFS substituted GPCs. It has been determined that WFS substitution decreases the overall cost, workability, water absorption, and sorptivity of GPC produced with various industrial wastes. It is reported that GPC produced with the addition of WFS has better resistance against acid and sulfate attack compared to conventional concrete. It is thought that a comprehensive investigation of features such as physical, chemical, mechanical, durability, microstructure, radiological, etc. of GPCs substituted with different ratios of WFS with interdisciplinary studies on subjects that have not been adequately researched in the literature will contribute to the literature in many ways. |
