Abstract

Due to growing environmental concerns of the cement industry alternative cement technologies have become an area of increasing interest. One such thing is “GEOPOLYMER CONCRETE”. It utilizes an alternate material including fly ash as binding material in place of cement. This fly ash reacts with alkaline solution NaOH and sodium silicate (Na2sio3) to form a gel which binds fine and coarse aggregates. Since geopolymer concrete is an emerging field, the guide lines from the bureau of Indian standards are yet to be formulated. An attempt has been made to find out an optimum mix for geopolymer concrete. Concrete cubes of size 150*150*150 mm were prepared. The compressive strength was found out at 7 days and 28 days.. When compared with conventional concrete or any other concrete method it is more advantageous, economical and eco friendly.
