Mechanical properties of geopolymer concrete with varying cement content using flyash and ground granulated blast furnace slag

In the recent past, importance of geopolymer concrete as an eco-friendly product to replace portland cement is continuously increasing over time. Yet less research effort has been invested in this area compared with some topical issues civil engineering. Thus, objective article analyse mechanical properties where replaced by fly ash and ground granulated blast-furnace slag (GGBS). Sodium silicate sodium hydroxide 8 molarity solution was used. The compressive strength a cube measured for various mixtures (i.e. G50F50 G F stand GGBS flyash, respectively while numerical value denotes percentage) contents 0, 10, 20, 30, 40%). specimens are 100mmx100mmx100mm ambient curing at 35- 400C. total, 9 cubes, 3 beams cylinders cast 7days, 14days 28days strengths different mixes cubes calculated. For 28days, flexural tensile strength. 7,14 28 days nearly doubled target using instead normal concrete. Compressive about 10% higher 7 20% after replacing 40% cement. Flexural increased 50% when but split only 1%.
