SUMMARY:

Dry concrete is a composite in which its components are mixed dry and is sold in bags, where water is added, in this semi-ready concrete, only when the material is to be used. The advantages are less waste of materials, quality control and dosed concrete can be supplied with the incorporation of different materials and special features. Thus, this research studies the development of a dry concrete incorporated with different contents of rubberized polyester fibers from the residual tires. For this, a defibration of the residue was carried out and the influence of the incorporation of 0, 2 and 2.5 kg / m³ of macrofibers by the volume of the concrete was studied, in a ratio of 1: 1.75: 2.83 (Cement: Sand: Gravel). The technical analysis was carried out through the slump test, physical indexes, resistance to axial compression, diametral and tensile strength in flexion. The concrete mix with the use of 2 kg / m³ was the one that presented the best results of resistance in axial compression and tensile strength in flexion.
