In this research the influence of the percentage of Aloe Vera on compressive strength, infiltration, capillary absorption, time of setting and settlement in a structural concrete is evaluated in order to determine the most optimum percentage by analyzing the fresh and hardened condition of the concrete. Costs was computed for the conformation of a cubic meter of concrete using industrialized additives (Sika) and Aloe vera. Fine aggregate was used with fineness modulus of 2.5, coarse aggregate of nominal maximum size of ¾ in. and type ICo cement. A study of the parts of the Aloe vera plant added in the concrete by the drip test was carried out, with which its best use was determined. A concrete mix design was performed according to ACI 211 (American Concrete Institute). The use of Aloe vera was in percentages of 1, 2, 3, 4, 5 and 6% with respect to the total of the concrete, using the li...
