Abstract

Morteros y hormigones basados en cemento Portland que exhiben una reducción importante de la fisuración por contracción cuando se formulan con combinaciones sinérgicas de óxido de magnesio (MgO), Mezclas de Reducción de Contracción (SRA) y Polímeros Super Absorbentes (SAP). El problema de usar estos es que MgO es un sólido que reacciona con agua, SRA es un líquido y SAP si no se añade de forma apropiada puede expulsar agua fuera del sistema y, así aumenta en lugar de disminuir la contracción. Esta invención además proporciona un medio para combinar los presentes productos para dar lugar a un aditivo.
