Influence of Fly Ash on the Compressive Strength of Foamed Concrete at Elevated Temperature
Faculty of Civil Engineering, Universiti Teknologi Mara Pulau Pinang, 13500 Permatang Pauh, Pulau Pinang
Foamed concrete is a lightweight concrete that is widely used in the construction industry recently. This study was carried out to investigate the influence of fly ash as a cement replacement material to the residual compressive strength of foamed concrete subjected to elevated temperature. For this study, the foamed concrete density was fixed at 1300 kg/m3 and the sand-cement ratio and water-cement was set at 1:2 and 0.45, respectively. The samples were prepared and tested at the age of 28 days. Based on the results, it has been found that with 25% inclusion of fly ash, the percentage of compressive strength loss was decreased by 3 – 50%.
