Resumen

La temperatura a la cual se desarrolla el proceso de activación alcalina es un factor significativo en la evolución de las propiedades mecánicas de material cementante base ceniza de carbón. En este trabajo se evaluó, a través del estudio de la evolución mineralógica de las fases cementantes por DRX y FTIR, la influencia de la temperatura (8 a 38 °C) y tiempo (3 y 28 días) de curado sobre las propiedades mecánicas de la síntesis alcalina de dos cenizas de carbón. Se encontró que el tipo de zeolita, producto de la síntesis, depende de los factores de estudio. Para valores superiores a 28 °C y mínimo 7 días, se lograron cementos activados alcalinamente con resistencias superiores a 20 MPa. Otros parámetros, como la relación SiO₂/Al₂O₃, el porcentaje de carbón inquemado y la distribución del tamaño de partícula, se deben de tener en cuenta en la variación del desempeño mecánico.
