| Today, the use of new additives in self-compacting concrete leads to the improvement of its mechanical properties. Palm groves are one of the vegetation covers of Behbahan city in Iran, which cover a large area of land in this region. In this research, due to the abundance of palm groves in the south of Iran, the idea of using date palm fibers in the self-compacting concrete mixing plan has been proposed. The fibers were cut into 3 cm lengths and used in self-compacting concrete as a natural, cheap, and readily available admixture. In this research, palm fibers were used to make self-compacting concrete to improve the mechanical properties of this concrete with percentages of 0%, 0.5%, 1%, 1.5%, and 2% weight of cement. The results of the tests showed that the tensile strength of self-compacting concrete with and without date palm fibers with percentages of 0.5%, 1%, 1.5%, and 2% by weight of cement in 7 and 28 days of processing were 16.37%, 34.27%, 56.39%, 82.24% and 13.56%, 27.61%, 46.96%, and 67.6% tensile strength increased compared to the self-compacting concrete sample without date fibers. The compressive strength of self-compacting concrete with and without date palm fibers with 0.5%, 1%, 1.5%, and 2% by weight of cement in 7 and 28 days of processing are 5.19%, 10.87%, 17.81%, 22.60%, and 4.11%, 9.51%, 15.48%, 22.47% respectively of the compressive strength decreased compared to the self-compacting concrete sample without date fibers. | ||
