There are several ways to reinforce concrete structures so far. One of these methods is to usewinding technique on a concrete structure with a fabric. In this study, first, rib knitted structures with andwithout weft inserted yarn were fabricated with two types of ordinary and high tenacity polyester yarn(with a low and high modulus). Then concrete columns were made and winded using produced fabricswith and without tension. The compression test was carried out on the winded columns. The results showthat with increasing tensile modulus of the fabric (such as weft inserted rib fabric with high tenacitypolyester yarn) the compressive strength of the concrete columns increases. Accordingly, while thesample had only 7.52% weight increase and 8.75% increase in diameter compared to the control sample,the bearing capacity of the column showed an increase of 88.55% compared to the control sample. Also,the compressive strength of concrete column is increased by increasing the number of layers windedaround the concrete column.
