Effect of marble dust blended with recycled coarse aggregate on self-compacting geopolymer concrete

Abstract

Abstract This investigation on the application of marble dust, ground granulated blast furnace slag (GGBS), and recycled coarse aggregate (RCA) in geopolymer concrete is presented in this research report. The study aims to determine whether it is possible to make concrete that is more environmentally friendly and sustainable while maintaining its desirable features. The creation and testing of various GGBS-based geopolymer concrete mixtures utilizing varying ratios of marble dust and RCA in a 12M NaOH solution were part of the research technique. In the experimental study, new concrete qualities were developed and examined by EFNARC requirements. The addition of marble dust and RCA has been found to significantly alter the geopolymer concrete’s characteristics. The study finds that employing RCA, GGBS, and marble dust can be successful.
