Abstract
Concrete, as one of the most widely used construction materials, has a brittle behavior. Adding fibers to concrete has an effect on formability, impact resistance, energy absorption rate, post-cracking resistance, abrasion resistance and tensile strength of concrete and prevents crack propagation. For this purpose, a research has been conducted to inves-tigate the effect of different combinations of polypropylene fibers, si-nusoidal steel fibers and colloidal nanosilica on the performance of flexural strength, compressive strength, tensile strength and water ab-sorption percentage of concrete. The results of the experiments show that by adding sinusoidal steel fibers and colloidal nanosilica to con-crete samples, bending strength, compressive strength and tensile strength are increased. The best mixing design is related to the sample of 7% of steel fibers and 3% of nano colloidal silica (S7N3), which the bending strength, compressive strength and tensile strength of this combination are 54.34, 35.62 and 26.31% respectively. The control sample (OPC) increases. In the sample containing 3% nanosilica (N3), compared to the control sample, water absorption has decreased by 32%.
