The effect of mineral admixtures on the properties

01-01-2000  The results, in general, showed that mineral admixtures improved the properties of high-performance concretes, but at different rates depending on the binder type. While SF contributed to both shortand long-term properties of concrete, FA required a relatively longer time to get its beneficial effect.
