Flexural behaviour of fly ash based geopolymer concrete

2021-1-1  Mean. 4.99. Based on the flexural test, the observed behaviour of the Geopolymer concrete beams are observed. The flexural strength for Geopolymer concrete with Fly ash replaced by 100%, are 4.85 N/mm2, 5.02 N/mm2 and 5.12 N/mm2 for 28th day. The average flexural strength is 4.99 N/mm2 for 28th day respectively.
