Evaluación de morteros con sustituto de cascarilla de arroz para complejos camaroneros

Abstract

Abstract: This research conducts tests on mortars with 20% rice husk ash (RHA) substitution, with the purpose of determining the compressive strength for its possible use in works in shrimp complexes. First, the rice husk was prepared to obtain RHA ash. Then, the fine aggregate and rice husk ash were characterized by means of a granulometric study, fineness modulus, density, absorption percentage, gravimetric mass and percentage of voids. Subsequently, the dosages for the specimens were determined, where 4 mixtures were prepared differentiating rice husk content between fresh water and salt water. Finally, the compressive strength of the 12 specimens was evaluated, where it was found that none of the mortars exceeded the required f'c of the design at 28 days. The mortar with the best performance was the one composed in the traditional way with fine aggregate and fresh water, while the mixture of salt water and RHA was the one with the worst compressive strength.
