Investigating the Characteristics of Engineering Properties of Concrete Made from Hormak River Sediments and Sistan Reed Fibers

The purpose of this research is to investigate the characteristics of engineering properties of concrete made from Hormak river sediments and Sistan reed fibers.in order to investigate the effect of reed fibers on the engineering properties of concrete, the ratio of water to cement in all designs is constant and equal to 195 to 410 and experiments have been performed on 5 samples containing fibers and without fibers, before determining the optimal amount of each From the mentioned fibers to strengthen the concrete, the results of the necessary tests on fresh and hardened concrete were examined. In this study, in addition to mixing reed fibers with concrete, laboratory methods such as Compressive and tensile strength were used to confirm the accuracy of the results and the importance of selecting suitable materials at low cost in a short time before the concrete mixing project. The results show that the addition of reed fibers to concrete has increased the compressive strength in concrete samples Comparing the results of this test in ordinary concrete and fiber reinforced concrete, showed that this increase in strength at the ages of 7 to 28 days has increased only in samples S2 and S3 and is Similar to the typical concrete example isS1, While in S4 and S5 samples, which were samples of three-row fibers, there is a large decrease in compressive strength. Adding reed fibers initially increases the compressive and tensile strengths, but over time reduces these resistances. DOI: https://doi.org/10.52783/pst.789
