Abstract

Concrete is a building material that is made up of fine concrete, coarse aggregate, water, and cement. Cement processing, on the other hand, produces a large number of carbon emissions, which contribute to global warming and climate change. Geopolymer concrete is an environmentally friendly alternative to traditional concrete, which uses fly ash as a binder material and GGBS as a fly ash replacement. To start the polymerization process, an alkaline activator made of sodium hydroxide and sodium silicate solutions is mixed with the binder material. In addition, geopolymer concrete has several advantages over conventional concrete, including high compressive strength, thermal resistance, and low cost. The effect of sodium hydroxide molarity on the strength properties of geopolymer concrete versus conventional concrete is discussed in this paper. The different molarities of NaOH used in the study were 8M, 10M, 12M, and 14M, and the results showed that the molarity of the mixture is directly proportional to compressive strength, so increasing the molarity increases the compressive strength of geopolymer concrete and vice versa. In addition, a questionnaire with a few questions about the importance of geopolymer concrete was developed. It could be concluded that responses say geopolymer concrete has better advantages over normal concrete and molarity impacts on strength properties of concrete
