This research investigates The combined Influence of PPF and SF on Concrete Strength. key variables Effects such as contents of PPF and SF were studied. An experimental plan was conducted to achieve the required objectives. Concrete mixes having a fixed water/binder ratio equals 0.40 and a constant total binder content equals 500kg/m3are prepared. The % of SF that replaced cement in this study were 0%,6%,12% and 18%. PPF with 12mm length and four volume fractions of 0%, 0.25%,0.5% and 0.75% are used. The results illustrate that SF posses great enhance on the concrete tensile and compressive strengths. The increasing of replacement of SF from 12% to 18% has no approximately significant change on the development of concrete strength. The adding of PPF caused an inverse influence on the strengths of plain and SF concretes.
