Metaheuristic Approach to Resolve the Real-World Problem of Binder in Concrete by Synthesizing Natural Iron-Rich Binder System Using Chemical Activation

Abstract

This research confirms the metaheuristic way using the novel method of synthesis of inorganic chemical activator binder just by replacing the Al3+ ion to Fe3+ ion by chemical activation in the matrix using Taguchi’s orthogonal array. The laterite soil was made reactive using calcination processes, and the material used was Fe2O3; as a major source, it is then combined with aluminosilicate substances such as low calcium fly ash, and ground granulated blast furnace slag (GGBFS) and Alccofine individually are considered as binder materials, which are activated using alkaline and acid-based chemical activation. Furthermore, the outcomes using Taguchi’s optimization technique with the compressive strength behavior of each chemical inorganic polymer binder to evaluate the best suitable combination of binder with suitable activator are studied, and also, the molarity required for polymerization process is identified using the same. This is found to be the most successful and economical way to solve the real-world problem of binder by preparing the binder system from the natural source and to control the greenhouse effect from the construction industry.
