Resumen
En la actualidad, las adiciones minerales son muy utilizadas ya que favorecen no solo la sustitución parcial del cemento Portland, la cual reduce la producción del clínker, sino que brinda ciertas propiedades químicas y físicas que hacen más durable el hormigón. El uso de aditivos y la adición de Materiales Cementicios Suplementarios (MCS) son factores que tienen gran influencia en las propiedades reológicas y físico-mecánicas. Es por ello que esta investigación se centra en evaluar el efecto de los aditivos Sikaplast 9100, SX32, y SRC 20 en morteros y hormigones producidos con adición mineral activa LC2. El trabajo consta de varias etapas: primeramente, se realiza un estudio de toda la bibliografía relacionada con el tema; en una segunda etapa se practican ensayos de consistencia y resistencia en morteros, y asentamiento, resistencia, resistividad y permeabilidad en hormigones; en una tercera y última etapa se interpretan los resultados y se analizan las propiedades reológicas y físico-mecánicas de los morteros y hormigones, ambos elaborados con un 40% de adición mineral activa LC2. Se logra con este estudio aportar una vía de sustitución del cemento Portland por adiciones, como es el caso del LC2 en combinación con aditivos que estén al alcance de la Industria de la Construcción en Cuba
Currently, mineral additions are widely used as they favor not only the partial replacement of Portland cement, which reduces clinker production, but also provides certain chemical and physical properties that make concrete more durable. The use of additives and the addition of Supplemental Cementitious Materials (MCS) are factors that have a great influence on rheological and physical-mechanical properties. That is why this research focuses on evaluating the effect of the additives Sikaplast 9100, SX32, and SRC 20 in mortars and concretes produced with active mineral addition LC2. The work consists of several stages: first, a study of all the literature related to the subject is carried out; in a second stage tests of consistency and resistance in mortars, and settlement, resistance, resistivity and permeability in concrete are practiced; In a third and final stage the results are interpreted and the rheological and physical-mechanical properties of the mortars and concretes are analyzed, both elaborated with 40% of active mineral addition LC2. This study provides a way of replacing Portland cement with additions, as is the case of LC2 in combination with additives that are within the reach of the Construction Industry in Cuba.
