Resumen
El presente trabajo evalua las diferentes formulaciones de cementos ternarios elaborados a escala de laboratorio sobre la base del sistema clínquer-arcilla calcinada-carbonato de calcio en la proporciones 2:1 y 1:1 y que comprende la sustitución de un 50 y 35% de sustitución del clínquer.
Para la fabricación de estos cementos se utilizaron materias primas tales como la caliza y el yeso, procedentes de la fábrica de cemento Siguaney, la arcilla del yacimiento “Neptuno” en Artemisa y posteriormente calcinada en la FCA y el cemento procedente de la fábrica Carl Marx en Cienfuegos.
La evaluación de los cementos obtenido se realizaron a través de los distintos ensayos físicomecánicos, la reología por medio del método del Minicono y la cinética de las reacciones fueron analizadas mediante Calorimetría Isotérmica. La influencia de la finura de los componentes del cemento compuesto fue analizada a través de la resistencia a la compresión y la evolución de calor.
En general los cementos en su mayoría cumplieron con la NC 96-2011. Cemento con adición activa. Especificaciones y las formulaciones obtenidas de los LC3 65 superaron en más de un 30% las resistencias esperadas.
The present work evaluates the different formulations of ternary cement made on a laboratory scale based on the calcination-calcium carbonate test system in the ratio 2: 1 and 1: 1 and comprising the substitution of 50 and 35% of clínquer replacement. For the manufacture of these cements he used raw materials such as limestone and gypsum, the Siguaney cement factory procedures, the "Neptune" ore deposit at Artemisa and then calcined the FCA and the cement comes from the Carl Marx in Hundred fires. The evaluation of the cements was carried out through the various physical-mechanical tests, the rheology by means of the Minicono method and the kinetics of the reactions were analyzed by Isothermal Calorimetry. The influence of the fineness of the components of the composite cement was analyzed through the compressive strength and the evolution of heat. In general the cements mostly complied with the NC 96-2011. Cement with active addition. Specifications and formulations obtained from the LC3 65 exceeded by more than 30% the expected resistances.
