Due to growing population, urbanization and industrialization, the utilization of cement in construction industries has been increasing day by day to fulfill the effective needs of infrastructure. The production of cement poses severe environmental problems due to excess emission of gaseous pollutants. Cement is an energy devouring and high greenhouse gas effuse object. The goal of this explore is to process a carbon dioxide free binding material. The Geopolymer concrete is such a requisite and promising one. Geopolymer is acquiring increased interest as it binds with little carbon-dioxide emission in contrast to Portland cement. The augment in need of environmental friendly construction has been the motive force for evolving defensible and cost-effective construction materials. In current investigation, mechanical and durability properties of Geopolymer concrete containing recycled concrete aggregates (RCA) are studied. The RCA is sourced from local C&D waste in Anantapur. Apart of this, quarry stone dust (QSD) is used for partially replacing sand that which is sourced from nearest quarry. Class F fly ash is used as the source material for the Geopolymer and 12M NaoH and Na2SiO3 as activators are used to polymer rise the fly ash. In this attentive study cube specimens of size 100×100 have been cast and tested. In curing of concrete at room temperature ambient curing has been endorsed. To evaluate strength parameters, compressive strength test is directed at the duration of 28 days and as a measure of durability, acid attack test is conducted on specimens that are immersed in 5%H2SO4 solution for a period of 30, 60 and 90 days. As from the test consequences, it can be concluded that GPC own excellent compressive strength and render good durability attributes. GPC can be used in construction industry efficiently, especially in precast members.
