| Popis: | The Geopolymer concrete is a new alternative for ordinary Portland cement concrete developed with environmental friendly materials. This paper apparently discussed the emphasis and benefits including mechanical properties of developed with Ground Granulated Blast Furnace slag (GGBS) and flyash as binding materials and alkaline activator (combination of sodium hydroxide and sodium silicate solution) for M25 grade of concrete. Various specimens are casted with and without GGBS (10%, 20%, and 30%) in fly ash with different strength activator ratios (1.5 and 2.5) to determine compressive strength, split tensile strength and ultrasonic pulse velocity test for 7 and 28 days under ambient curing and oven curing at 60 °C for 24 h. From the results, it is concluded that that geopolymer concrete with 30% GGBS replacement and 1.5 strength ratio better properties compared to all mixes. |
