    An experimental study on determining the strength properties of frc with numerous mix proportions
    (2021) Nasir Ullah; Saddam Hussain; M.M Talha Umar; Zafar Ullah
    Worldwide researches are being conducted regarding the use of fibers in the concrete. Fibers are very effective way to strengthen and increase lifespan of the structure. It is considered suitable and advanced method as compared to previous traditional method to strengthen the concrete. The aim of this xperimental research work is to determine the strength properties of Fiber reinforced concrete with numerous mix proportions. Total of 20 samples with numerous mix proportions of steel and glass fibers of M25 grade concrete are tested, six of them with glass fibers percentage of 5%, 10% and 15% and six of steel fibers with same percentage of glass fibers by the weight of cement. Two samples with percentage of 5% of glass fibers and 10% steel fibers, two samples of 10% of glass fibers and 5% of steel fibers and two samples of 7.5% glass fibers and 7.5% steel fibers, compared with control sample with no fibers. All the specimens were cured for the period of 7 and 28 days before crushing. The results of fiber reinforced concrete for 7days and 28days curing with varied percentage of fiber were studied and it has been found that the higher reinforcement of the glass fibers had a significant adverse impact on the compressive strength while steel fibers had less impact on compressive strength. The highest compressive strength was achieved with the addition of 5% steel fibers at the age of 28 days, a further increase in fibers content decreased the compressive strength. The lowest compressive strength was gained at 15% glass fibers at the age of 28 days. The compressive strength of steel fibers with the addition of 5% steel is 8.43% more than control sample and with 10% SF than the percentage is 8.06% more. With the addition of 5% glass fibers the compressive strength is 8.17% more than the control sample. Further increase in percentage of SF and GF this percentage of strength decreases
