Experimental investigation on performance evaluation of geopolymer concrete with coatings

Abstract

This research work is to experimentally evaluate the behavior of newlinegeopolymer concrete with coating, for its strength and durability behaviour. The newlineprimary objective of the study is to concentrate on two major categories, namely newlinegeopolymer and coatings. The objective of this study is to develop a geopolymer newlinethat is both environmentally friendly and long-lasting by utilising the appropriate newlineproportion of source materials, such as fly ash and GGBS. Additionally, the newlinestudy aims to determine the coating system that can be effectively utilised in fly newlineash-GGBS sourced geopolymer concrete, with the goal of improving both its newlineperformance and its durability. newlineThe total study is separated into two phases, and the purpose of this newlineresearch activity is to determine the optimal source material distribution among newlinefly ash and GGBS in geopolymer concrete based on mechanical strength. This is newlinebased on the research gap that was recognised and the target that was established newlinefor the study. In order to get an understanding of the behaviour of alkali newlineactivated geopolymer paste, it is necessary to investigate its mechanical and newlinedurability properties, as well as the coating materials (OPC, geopolymer, and newlineacrylic) that are used as additives. Utilising a metaheuristic technique (the ABO newlinealgorithm) and developing a model in order to determine which of the three newlinecoating systems oil-polymer coating, acrylic coating, and OPC coating is newlinethe most effective. In order to investigate and get an understanding of the newlinemechanical behaviour of flyash-GGBS based geopolymer concrete with and newlinewithout coatings in a range of hydroxide molarity and The purpose of this newlineresearch is to investigate and comprehend the durability and microstructural newlinebehaviour of geopolymer concrete based on fly ash and GGBS, both with and newlinewithout coatings, in a multitude of hydroxide molarities. newline
