Resumen

En la naturaleza, los ácidos grasos se encuentran en forma de ésteres con glicerina (grasas) y son ampliamente usados para la fabricación de jabones, pinturas de aceite, medicamentos y productos cosméticos. En este estudio fue de particular interés la aplicación de derivados organosilíceos del ácido oleico para la producción de un revestimiento que cubriera la superficie del hormigón y lo protegiera de la permeación del agua. Como resultado de la silanización propuesta, la superficie del hormigón adquirió carácter hidrofóbico con los ángulos de mojado hasta 115º, y su capacidad de absorción se redujo hasta en un 93%.
