Grouting is being used as one of the suitable ground improvement methods since long time. Cement grouts have been used to improve the engineering properties of soil/rock for instance, to increase the cohesion and shear strength, to reduce the settlement, to reduce the compressibility and permeability of deposits. Grouting is also used to increase the strength of the soil and thus it reduces the potential of liquefaction. Depending upon the materials used for making the grout, it is divided into two major types, i.e. cement grouting and chemical grouting. Considering the sustainability aspect of grouting technology instead of using cement grout, the proposed study focuses on the use of alternate binding material for grouting. The geopolymer, as an alternative binding material, is one of the recent areas of research and also used in the construction industry. The geopolymer technology utilizes the silica and alumina rich industrial waste materials and alkaline solution to activate these materials. Using this geopolymer technology, the grout can be prepared which has the potential to replace the cement grout for a particular application. In this study, the grout was prepared from the geopolymer material considering its setting time and compressive strength as a design parameter. The present study has an objective to design the grout using geopolymer materials such as fly ash and sodium hydroxide and sodium silicate as an alkaline activator. The effort has been made to check the feasibility of the designed grout such that it can have the potential to become a cost-effective, eco-friendly, and sustainable solution in the geotechnical field. The soil sample taken for the study is granular soil for the application of the designed geopolymer grout.
