In this research was evaluated the influence of Aloe vera in the concrete to determine the most optimum percentage by analyzing the fresh and hardened condition of the concrete. A study of the parts of the Aloe vera plant by the drip test was carried out, with which its best use was determined. The mix design for a concrete 210 kg/cm2 was made according to ACI 211 (American Concrete Institute). The use of Aloe vera was in percentages of 0-6% with respect to the total of the concrete. The tests were conducted under the American Society for Testing Materials (ASTM) standards C39, C1701, C403 and C143 and A Spanish Norm European Norm (UNE-EN 1925). The water content of the Aloe vera gel was 98%. The best use of the plant was achieved to 2% with: the bark, gel 2mm and the Aloin. The settling decreased linearly, the initial setting favored almost double and approximately 7.6 times more for the final setting. The compressive strength reached 355 kg/cm2 (increase of 41% of compressive strength). Permeability decreased by 47,9% in terms of infiltration rate with 0.039 in/hr and Capillary absorption decreased 32% with 1,9 g/m2xseg0.5.
