N2 - The useful life of concrete in areas prone to freezing and thawing has been a challenge for its preservation, since these environments cause cracks and deterioration in the material. Therefore, the purpose of this research was to determine a concrete durable to freezing and thawing under the standards of ASTM 666, which is made of a material of the fourth glaciation-the morainic aggregate, for which air incorporating additive was used. Preliminarily, for compressive strength, values of 33.72 MPa were obtained in the samples without incorporating air subjected to freezing and thawing; however, in the samples when incorporating air subjected to freezing and thawing, it was reduced to 31.18 MPa. Next, for the tensile strength, values of 3.88 MPa were obtained in the samples without incorporating air subjected to freezing and thawing; however, in the samples when incorporating air subjected to freezing and thawing, it was reduced to 3.31 MPa. Finally, it is concluded that the use of morainic aggregate in concrete improves compressive and tensile strength. Despite the moderate loss of strength due to freeze-thaw cycles, the concrete still retains superior mechanical strength compared to its design strength.
