摘要: This paper presents the experimental results on behavior of fly ash geopolymer concrete incorporating bamboo desired temperature (200 °C to 800 °C). Different amounts were investigated and was considered as control sample. The synthesized with sodium hydroxide silicate solutions. Ultrasonic pulse velocity, weight loss, residual compressive strength determined, all samples tested two different cooling approaches i.e., an air-cooling (AC) water-cooling (WC) regime. Results from these tests show that addition 5% in ash, exhibited a 5 MPa (53%) 5.65 (66%) improvement strength, well 940 m/s (76%) 727 greater ultrasonic velocity AC WC, respectively, at when compared samples. Thus, can be one alternatives it faces exposure high temperatures.
