Abstract
En un método para mejorar un producto de cemento curado, se exponen matrices de cemento curado a CO2 en fase densa o supercrítico, el cual entrala matriz a través de pasajes en la misma para neutralizar la alcalinidad natural del cemento, de manera que los materiales intolerantes al álcali puedanser incorporados en el cemento. El CO2 convierte el hidróxido cálcico en el cemento en carbonato cálcico y agua, y la alta presión del CO2 en fase densa osupercrítico forma cristales redondos, estrechamente empaquetados y alineados con pocos o no visibles poros o vasos capilares, para perfeccionar lahomogeneidad y firmeza del cemento curado y su enlace con, por ejemplo, fibras de vidrio reforzantes no revestidas. El CO2 supercrítico puede ser usado paratransportar otros materiales orgánicos o inorgánicos, incluyendo metal pulverizado, en solución o suspensión, al interior de la matriz de cemento paraalterar sus características químicas y/o físicas. El CO2 supercrítico puede además ser utilizado para determinar rápidamente si un espécimen particular decemento proviene de una mezcla de cemento líquida a la cual se le ha agregado un material que evita u obstaculiza la carbonatación del cemento.
