“…Hernandez-Zaragoza et al (12) studied Portland cement mortar with a w/c ratio of 0.60 containing lyophilized cactus gum. Their results indicated a 65% compressive strength increase with respect to the control mortar at only three days of age, which is contrary to other studies in which the addition of cactus mucilage extended the setting times and also negatively affected the compressive strength gain at early ages as well as at 28 days (11,13). Moreover, their results fail to provide a clear trend for either increasing or decreasing compressive strength with increasing lyophilized cactus gum concentration.…”

“…The tests were undertaken at later ages (60 and 120 days of age) because of the retarding effect on the development of mechanical properties reported in the literature when using cactus mucilage (11,13).

“…Therefore, higher compressive strength at only three days with respect to the control cannot be expected and it is not feasible to make strong conclusions from their data. Chandra et al (11) reported increases in compressive strength of 6% and 12% in mortar containing 50% and 100% of cactus mucilage solution replacing the mixing water compared to the control at 90 days of age. Before this age, the compressive strength of concrete containing cactus mucilage was always lower than the control.…”

“…Therefore, in a system of finer pores and higher tortuosity, the capillary flow should be lower compared to systems of larger and more connected pores. Chandra et al (11) suggests that the reduction in water absorption when cactus mucilage is added to mortars is because a film formed by the admixture and the calcium complexes formed during the interaction between the cactus mucilage and the divalent calcium ions, seals the pores. Similarly, the alginate found in the seaweed extract, reacts with calcium ions to form spheres of calcium alginate ( Figure 9).…”

“…The lime pastes made with higher mucilage/lime ratios had an increased fracture resistance. Chandra et al (11) studied the interaction between cactus mucilage and Portland cement in mortar with a w/c ratio of 0.50. They observed improved workability in fresh mortar containing cactus extract.…”

This paper presents the mechanical performance and durability of concrete with water/cement (w/c) ratios of 0.30 and 0.60 containing cactus mucilage and brown marine seaweed extract solutions (at 0.5° Brix concentrations). Cylindrical specimens (100 mm×200 mm) were cast and moist-cured for 0 and 28 days. Compressive strength, rapid chloride permeability, and chloride diffusion tests were conducted to evaluate all of the concrete mixes at the ages of 60 and 120 days. In addition, accelerated carbonation tests were carried out on specimens at the age of 180 days by exposure to 23 °C, 60% RH and at 4.4% CO 2 for 120 days. The compressive strength results showed that only one concrete mix with admixtures increased in strength compared to the control. Regarding the rapid chloride permeability, chloride diffusion and carbonation, the results indicated that the durability of concretes containing organic additions was enhanced compared to the control. RESUMEN: Influencia del mucílago de cactus y extracto de algas pardas marinas en la resistencia a compresión y durabilidad del hormigón.Este trabajo presenta el comportamiento mecánico y de durabilidad de concretos con relaciones agua/cemento de 0.30 y 0.60, conteniendo soluciones de mucílago de nopal y extracto de algas marinas cafés (0.5 °Brix de concentración). Especímenes cilíndricos (100 mm×200 mm) fueron elaborados y curados en húmedo por 0 y 28 días. Se evaluó la resistencia a la compresión, permeabilidad rápida y difusión de cloruros a los 60 y 120 días de edad. Adicionalmente, se realizaron pruebas de carbonatación acelerada en especímenes con 180 días de edad, expuestos a 23 °C, 60% HR y 4.4% de CO 2 por 120 días. Los resultados de resistencia a la compresión muestran que únicamente una mezcla de concreto con adición orgánica incrementó su resistencia con respecto al control. Con respecto a la permeabilidad rápida a cloruros, difusión de cloruros y carbonatación, los resultados indican que la durabilidad de los concretos que contenían adiciones orgánicas fue mejorada con respecto al control.

BACKGROUND: This investigation presents experimental results concerning water and chloride permeability of cement-based mortar specimens fabricated with botanical (green) dehydrated additions such as Nopal (Opuntia ficus-indica) and Aloe vera.Mortar without such additions served as control. The natural dehydrated additions, Nopal or Aloe vera, were mixed with ordinary Portland cement and sand at different percentages of cement replacement (0%, 1%, 2%, 4%, or 8% of the cement mass). To characterize water and chloride ion transport in such mortars, 5 × 5 × 10-cm prisms were fabricated (three prisms per mixture). RESULTS:The results showed improvements in both water absorption-desorption (on average: 10% decrease in capillary absorption; 6% increase in water penetration resistance; 58% decrease in effective capillary porosity; and 2% decrease in capillary sorption) and chloride transport (14% decrease in surface chloride concentration, and 31% decrease in chloride concentration at 7 cm into the mortar) within the dehydrated Nopal replacement mixtures (≤2% of the cement mass). Aloe vera additions did not improve the corresponding parameters of water and chloride ion transport into the mortar. (water, chloride ions, etc.) into the material through its network of pores. Additions of dehydrated Aloe vera did not improve the protective performance of mortar against water and chloride ion transport and are, therefore, not suitable for increasing the durability of such cement-based materials. Figure 1 shows the typical results obtained with this method, showing the change in mass of the cubes ([W t −W 0 ] A −1 ) as a function of t for the tested mixtures. Specimen designations in all J Chem Technol Biotechnol 2019; 94: 3488-3494 CONCLUSIONS: Addition of dehydrated Nopal (≤2% of the cement mass) powder to cement-based material (mortar) may increase its durability as most aspects of durability are related to the absorption of aggressive agents Water permeability
