Characterization of two calcium aluminate cement pastes
, 2021 Este capítulo examina la caracterización de cementos de aluminato de calcio (CAC) con 52% en peso y 71% en peso de contenido de alúmina. Las muestras de pasta de cemento se fabricaron en proporciones de agua a cemento de 0,4 y 0,5 (a / c). La microestructura tanto de los polvos de cemento crudo como de sus correspondientes muestras se caracterizaron ...
