Abstract
The sustainable manufacture of self-compacting geopolymer concrete (SCGC), which has a lower carbon footprint compared with traditional concrete, reflects environmentally friendly concrete. In addition to the physical properties, this article presents an analysis of the fresh and mechanical properties of self-compacting geopolymer concrete. Some parameters such as varied sodium hydroxide molarity from 8 M to 16 M, sodium hydroxide/silicate solution ratio from 1:2.5 alkaline to GGBS, extra water ratio, GGBS content from 400 Kg/m3 to 500 Kg/m3. The current experimental evaluation examines the effectiveness of GGBS in improving SCGC workability and compressive strength due to durability. The sodium hydroxide molarity rises marginally reducing the fresh properties of self-compacting geopolymer concrete. As in the case of self-compacting concrete (SCC) with Portland cement, the durability properties of self-compacting geopolymer concrete are just a fraction of the compressive strength. The durability properties of self-compacting geopolymer concrete are adversely affected by rising test results of physical properties. Out of 5 different SCGC mix series, the optimum mix was achieved when a hundred percent Ground Granulated blast furnace slag (GGBS) and fifty percent river and M-sand were used, which not only showed better compressive strength and durability but also produced adequate workability within the EFNARC Self-Compacting Concrete (SCC) limits.
