Resumen
Teniendo en cuenta el potencial de los cementos geopoliméricos como una alternativa para sustituir parcialmente al cemento Portland, este artículo presenta el análisis del efecto que tienen las condiciones de curado de los cementos geopoliméricos sobre su desempeño mecánico. Las variables evaluadas durante el proceso de curado fueron tiempo, humedad y temperatura. Además, se describe el comportamiento de estas variables de acuerdo con los métodos de curado que han sido estudiados y evaluados hasta el momento en los cementos geopoliméricos con base de ceniza volante. Para llevar a cabo la revisión bibliográfica fue usado Scopus como herramienta principal de búsqueda, a partir de la palabra clave “cementos geopoliméricos”. Se identificaron más de 90 documentos relevantes tras aplicar filtros específicos y revisar sus resúmenes. Finalmente, se realizó una lectura y análisis detallado de los datos bibliográficos, que aportaron información relevante para el tema de estudio. Los procedimientos publicados muestran que no hay unanimidad para definir el mejor método de curado para este tipo de material; sin embargo, las condiciones más aceptadas para el desarrollo de mayores resistencias a la compresión son temperaturas entre 60 y 80 °C, con humedad controlada (sellado), durante un periodo de 4 a 12 horas. En general, esta revisión sirve como una guía para proponer, estudiar y aplicar diferentes procesos de curado en cementos geopoliméricos con base de ceniza volante, buscando optimizar su desempeño mecánico.
