Effect of Utilization of Agro-based Materials in Geopolymer – A Review

The global emission of greenhouse gases is largely attributable to the construction industry. One practical way to address environmental issues is to use waste resources in concrete. Farm manure is widely used in place of cement in the production of environmentally friendly concrete. Large quantities of Rice Husk Ash (RHA) are produced yearly, most of which is disposed of in landfills, severely degrading the environment. The usage of RHA as a precursor or alkaline binder in the synthesis of alkali-activated geopolymer, which is thought to be a workable way to lessen the serious issue and as well to prevent it. This new material is superior to conventional materials in terms of price and performance. This paper aims to outline an overview of the research on the application of geopolymer based on agro waste ash as a long-term, ecologically benign, and affordable building material. This study offers a thorough examination of the physio mechanical and workability characteristics of geopolymer concrete made of rice husk ash from agro-waste. The findings added to the body of evidence supporting the viability and sustainability of replacing conventional cement-based materials with geopolymer concrete that contains derivatives of agricultural waste as binding agents.
