Resumen
En la actualidad el uso de las adiciones minerales y de los cementos mezclados permite un ahorro de energía; de combustible, no solamente a nivel de fábrica o de empresa, sino a nivel de país; la protección y cuidado del medio ambiente, y brinda al hormigón ciertas propiedades que lo hacen más durable. En Cuba se implementa el uso de dos adiciones como solución alternativa ante esta característica, una es el cemento mezclado PP35 (adición del 15% de tobas zeolíticas) y la otra es Cemento de Bajo Carbono LC3 (adición arcilla calcinada, caliza y yeso (LC2)). Esta investigación se centra en la introducción de las adiciones puzolánicas en las construcciones hoteleras de Cayo Santa María, en la provincia de Villa Clara, Cuba, debido a los problemas de fisuración que presentan las estructuras. El trabajo consta de varias etapas, en una primera etapa se realiza un estudio de la bibliografía relacionada con el tema; en la segunda etapa luego de seleccionar y caracterizar los materiales se elaboran los morteros para realizar los ensayos como resistencia mecánica, absorción de agua por capilaridad y el ensayo de retracción por el canal. En una tercera y última etapa se interpretan los resultados y se analizan las propiedades físico-mecánicas de los morteros y la influencia con respecto al hormigón, ambos elaborados con un 15 y un 30% de adición mineral activa LC2.
Currently the use of mineral additions and mixed cements allows energy savings; of fuel, not only at the factory or company level, but at the country level; the protection and care of the environment, and gives concrete certain properties that make it more durable. In Cuba the use of two additions is implemented as an alternative solution to this characteristic, one is the mixed cement PP35 (addition of 15% of zeolitic tuffs) and the other is Low Carbon Cement LC3 (addition of calcined clay, limestone and gypsum (LC2)). This research focuses on the introduction of pozzolanic additions in the hotel buildings of Cayo Santa María, in the province of Villa Clara, Cuba, due to the cracking problems presented by the structures. The work consists of several stages, in a first stage a study of the bibliography related to the subject is carried out; in the second stage after selecting and characterizing the materials, the mortars are made to carry out the tests such as mechanical resistance, water absorption by capillarity and retraction test by the channel. In a third and final stage the results are interpreted and the physical-mechanical properties of the mortars and the influence with respect to the concrete are analyzed, both elaborated with 15 and 30% of active mineral addition LC2.
