Compressive and Flexural Strengths for Considerable Volume Fly-Ash Concrete

Abstract The use of considerable volume of fly ash concrete in replacement of cement is economically and environ-mentally benefic because the fly ash is cheaper and produces fewer emissions of greenhouse gases than the conventional Portland cement. By using 30; 40 and 50 percent of fly ash in cementitious materials, after comparing different results of samples tested, the 28 days high-performance fly ash concrete resisted to the compressive loading forces respectively equal to 30.9MPa; 29.7MPa and 26.2 MPa while for flexural loading forces, the high-performance fly ash concrete resisted re-spectively 5.1 MPa; 4.0MPa and 3. 9 MPa. These results were found after an experimental study done in the concrete labo-ratory and may inspire the sustainable construction especially for infrastructures with no high loading forces
