INTRODUCTION In 1978, Davidovits suggested that a binder could be generated by a polymerization process including a response between soluble fluids and mixes containing aluminium and silicon. The folios made were termed as “geo polymers”. Not at all like normal Portland/ pozzolanic bonds,geopolymers don’t frame calcium-silicate-hydrates (CSHs) for matrix formative and strength , yet silica and alumina responding with an alkaline solution and creates an alumina silicate gel that ties the aggregates and gives the strength of concrete ,source materials and antacid fluids/alkaline fluids are the tow primary constituents of geo polymers, the strengths of which rely on the nature of the materials and the sorts of fluids. Materials containing silicon (Si) and aluminum (Al) in indistinct structure, which originate from characteristic materials or by-item materials, could be utilized as source materials for geopolymers. kaolinite, clay, etc., are incorporated into the common materials bunch though fly cinder, silica smoke, granulated ground blast slag, rice-husk fiery debris, red mud etc., are by products obtained from various sources. For the production of geo polymers, the decision of source materials depends majorly on their accessibility and expense, the sort of utilization and the particular interest of the clients. Fly powder based geo polymers cements give phenomenal building properties that
