Objectives: To study the formation of geopolymer repair mortar; Secondly, results of repair mortar are to be evaluated in comparison with commercial repair mortar. Methods/Statistical Analysis: The methodology adopted in this research is about geo-polymer repair mortar. For this method, geo-polymer mortar is made to repair cracks and to increase the compressive strength of structure. Polymerization technique is employed for making mortar. With this research the waste material like fly ash is added to mortar with lesser cement content that holds it up economic. Compressive test and split tensile test were performed. Findings: The research arrives at the conclusion of the reduction in pollution with good compressive strength. The addition of fly ash in cement mortar makes it lighter and helps in gaining good strength. Due to low cement content and higher the fly ash content, it is compared with commercial repair mortar resulting better results. The study evaluates the difference in cost and the time taken. Therefore, when the addition of fly ash increases up to some percent the cost of the material decreases by 20-30% after comparing with commercial repair mortar due to which it is easier and more helpful for Indian construction companies to maintain budget easily. Application/Improvements: Geopolymer mortar servers many applications which include: better scheduling of cost, recognition of time, cost estimation during whole project. *Author for correspondence
