Abstract

Today's cement concrete industry is a major polluter. Cement, used as a binder in cement concrete, is made by high-temperature combustion, which raises atmospheric CO2 levels and contributes to climate change and natural resource depletion. As raw supplies diminish, several governments begin to levy carbon taxes. Numerous research have been undertaken to produce an innovative and ecologically advantageous construction material known as Geopolymer concrete (GC) in order to minimise and eliminate greenhouse gas emissions. In order to connect coarse aggregates (CA), fine aggregates (FA), and other materials in GC and improve concrete quality while using fewer natural resources, it is essential to replace cement with a byproduct substance rich in silicon and aluminium, such as red mud, fly ash (FA), rice husk ash (RHA), silica fume (SF), ground granulated blast furnace slag (GGBS), and others, activated by a high alkaline solution (AS). In this study were surveyed online and precast self-compacting geopolymer concrete's sustainability was examined. The data underwent factor analysis. Principal component analysis is used to extract factors. According to the research, there are 9 key variables to consider: Reduction in Carbon Footprint, Utilization of Waste Materials, Environmentally Friendly, Reduce Water usage during production, Low Maintenance, Augmentation of Mechanical Properties of Concrete, Natural Materials, Cost Effective, Reduction in Energy consumption during production. These are the nine primary sustainability criteria of Self-Compacting Geopolymer Concrete for Precast Construction.
