This study presents the effect of glass fiber and recycled aggregates on the strength properties of Geopolymer Concrete (GPC). The recycled aggregates were incorporated as a partial substitute for the natural coarse aggregates in the geopolymer concrete at 50%, 80%, and 100% by weight, and the results were compared to natural coarse aggregate. Class F fly ash is utilized as the source material for the production of Geopolymer and brought in from local sources. The effect of glass fiber (alkali resistant) with a length of 36 mm is also studied for the content ranging from 0.3, 1, 2, 3, and 3.5% based on the weight of the concrete. The flexural strength and compressive strength were compared at 7 days and 28 days for different cases. The results show that 1%, 1.5%, 2%, and 2.5% of glass fiber have exceeded the flexural strength of the geopolymer concrete by 20%.
-As of late the ascent of substantial creation costs has consistently been a worry of substantial makers and customers. Using current waste to override concrete and some poIn ongoing years the ascent of substantial creation costs has consistently been a worry of substantial makers and buyers. Using present day waste to override concrete and some bit of all out can diminish its cost and environmental dirt of all out can decrease its cost and natural tainting. The mark to the purpose of this paper to audit the shot at powder made from marble dust close by the copper slag as an in part substitution to fine aggregate all out in geo-polymer concrete. Marble dust powder was used in mix in comprise copper slag as in part substitution to fine aggregate in level of 10%, 20%, 30%, 40% and 50%. The strength of geo-polymer concrete was tested after 7 & 28 days. Result shows that compressive strength is increased after the replacement of 60% of copper slag and marble dust powder to fine aggregate and also flexural strength and split tensile strength increases strength upto 60% and 80% after replacement. These discoveries of the examination express that powdered marble dust will be utilized as the conceivable substitution material to fine aggregate to give maximum strength copper slag geo-polymer concrete.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
