Procesamiento de materiales cementantes a base de concha marina y tusa de maíz, su influencia como aditivo para morteros

Abstract

Abstract: The emission of pollutants negatively affects the various ecosystems globally, which is why we seek to produce materials with low environmental impact in the field of construction. This research addresses the experimental development of masonry mortars, composed of marine waste that incorporates seashells (Cm) and agricultural waste such as corn hustle (Tm) with a substitution percentage of 5% and 10%. They were recycled and crushed into a medium-sized fine powder that was used as an alternative raw material. Both (Cm) and (Tm) residues were activated under thermal conditions in an industrial furnace at 800 °C for two hours. Mechanical and physical tests were carried out to determine its compression, flexural, immersion absorption, bulk density and capillary absorption properties at an age of 28 days. Its results show that the union of 5% Cm and 10% Tm (C5%-M10%) is the most optimal percentage, qualifying it as a mortar with the highest resistance, as long as it does not exceed 15% substitution.
