Resumen
El presente trabajo investigativo tiene como objetivo general diseñar una mezcla
de hormigón a partir del uso del cemento LC3 para la construcción de una obra
escultórica del grupo Tezontle a presentarse en la Bienal de La Habana 2019. Se
evalúa el comportamiento de hormigones elaborados con LC3, tanto sus
propiedades reológicas como físico-mecánicas. En la construcción del cimiento de
la estructura se utilizó un diseño de mezcla en la que solamente se empleó
Cemento Portland Ordinario (CPO). Durante la fabricación de la superestructura
se implementó un diseño que incluía una dosificación de 55% de CPO y 45% de
adición mineral activa (LC2). Para la evaluación de los hormigones elaborados
con LC3 y Portland P-35 (patrón de referencia), en estado fresco y en estado
endurecido, se realizaron ensayos durante tres días de trabajo midiendo
asentamiento y resistencia a la compresión a los 3; 7 y 28 días. Se realizaron un
total de 14 ensayos de Cono de Abrams y 36 probetas de 15x30.
Palabras claves: hormigón, LC3, ensayo, asentamiento, resistencia.
The main objective of this research work is to design a concrete mixture based on the use of LC3 cement for the construction of a Tezontle sculptural work to be presented at the Havana Biennial 2019. The behavior of concrete made with LC3 is evaluated, both its rheological and physical-mechanical properties. In the construction of the foundation of the structure, a mixing design was used in which only Ordinary Portland Cement (CPO) was used. During the fabrication of the superstructure, a design was implemented that included a dosage of 55% CPO and 45% active mineral addition (LC2). For the evaluation of the concretes made with LC3 and Portland P-35 (reference standard), in a fresh state and in a hardened state, tests were carried out during three working days measuring settlement and resistance to compression at 3, 7 and 28 days. A total of 14 Abrams Cone tests and 36 15 × 30 specimens were made. Keywords: Concrete, LC3, settlement, resistance
