Physical Properties of Cement-Based Paste and Mortar With Dehydrated Cacti Additions

This article presents results for the physical characterization of mortar cubes fabricated with botanical (green) dehydrated additions such as nopal (Opuntia ficus indica) and aloe vera. A total of 84 mortar cubes were fabricated with and without these natural additions and tested for a period up to 900 days. Mortar without such additions served as controls. The natural dehydrated additions, nopal and aloe vera, were mixed with CPO cement (the name used in Mexico for type I Portland cement) at different percent replacements (0%, 1%, 2%, and 4%). To characterize physical properties of such mixtures, four tests were performed at ?900 days: total void content, compressive strength, ultrasound wave propagation, and wet electrical resistivity. Marginal improvements were observed within the dehydrated aloe vera replacement mixtures. Dehydrated nopal additions did increase the physical performance of the mortar with time.
