Development of a Portland Cement-Based Material with Agave salmiana Leaves Bioaggregate by Rosas Díaz, Felipe Esteban, García Hernández, David Gilberto, Mendoza Rangel, José Manuel, Terán Torres, Bernardo Tadeo, Galindo Rodríguez, Sergio Arturo, Juárez Alvarado, César Antonio

“…The objective of the research was to develop plant-based concretes with a matrix based on Portland cement and an aggregate of Agave salmiana (AS) leaves, obtained from the residues of the tequila industry that have no current purpose, as a total replacement for the calcareous aggregates commonly used in the manufacturing of mortars and whose extraction is associated with high levels of pollution, to improve their thermal properties and reduce the energy demand for air conditioning in homes. Characterization tests were carried out on the raw materials and the vegetal aggregate was processed to improve its compatibility with the cement paste through four different treatments: (a) freezing (T/C), (b) hornification (T/H), (c) sodium hydroxide (T/NaOH), and (d) solid paraffin (T/P). …”

Bromate and chromate removal from water by double layered hydroxides by Villanueva Rangel, Cecilia Patricia

“…Adsorption kinetics of chromate on DHL31500 was affected by the stirring type (mechanical, magnetic, intermittent, and oscillatory mixing), but the intermittent mode allowed the maximum chromate uptake as well as bubbling argon gas to the initial solution in order to displace the air in a closed vessel and to avoid carbon dioxide absorption along the experiment. …”
