Abstract
Geo binder is a sustainable binding material that produces no emissions of carbon dioxide during curing and after curing. Aggregates contribute more than 65% for producing geopolymer concrete. The Eco-friendly sand material and Cost effective material called Manufacture sand was used as a partial replacement material for fine aggregates by various percentages. Manufacture sand is generally produced by crushing, screening and washing a rock in desired shapes and sizes. Electronic waste is one of the hazardous waste materials; it is a non-degradable waste material creates harmful effects on environment. Such materials are cost effective for processing, other than using this process to make it degradable; these electronic materials were replaced here partially in place of fine aggregates which are a very cost effective technique for degrading from earth. Polypropylene fibers were used in concrete to avoid micro cracks and to get the closed surface of concrete which in terms give good strength. Manufacture sand and electronic waste was partially replaced by fine aggregates in 10%, 20%, 30%, 40% and 50%. Mix designs were prepared and casted separately and then tests were carried out and then the results were compared with respect to conventional geopolymer concrete and concrete made by replacement materials.
