Abstract: The modern engineering has successfully involved in developing innovative, sustainable, green and recycled products in the manufacture of concrete. In India, the demand of natural sand is quite high due to the rapid infrastructural growth. The abundance availability of Fly ash and bottom ash that needed to be disposed of in a friendly way. Bottom ash has potential to be used as concrete material in place of fine aggregate. This paper elaborates the effect of bottom ash as fine aggregate in Geopolymer concrete. Bottom ash used as fine aggregate replaced partially in geopolymer concrete. GGBFS is used as Cement replacement in geopolymer concrete. NaOH and Na2SiO3 activator are used as binder in geopolymer concrete. The test involved designation of 20%, 40 % & 60% of bottom ash (BA) as a partial replacement of fine aggregate to study the engineering properties (compression test, split tensile strength) and the functional properties (test on sulphate resistance, salt water resistance, test on acid resistance, RCPT, sorptivity also quality assessment test (UPV test) and the test results indicate that there is decrease in compressive stress with increase of bottom ash, it is observed that 20%to 40% replacement of bottom ash has good strength and durability
