Compressive and Flexural Strengths for Considerable Volume Fly-Ash Concrete

The use of considerable volume of fly ash concrete in replacement of cement is economically and environmentally 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 respectively 5.1 MPa; 4.0MPa and 3. 9 MPa. These results were found after an experimental study done in the concrete laboratory and may inspire the sustainable construction especially for infrastructures with no high loading forces.
