ULTRAFINE PARTICLES FOR THE MAKING OF VERY HIGH STRENGTH CONCRETES

The manufacture of very high strength concrete (28-day compressive strength higher than 80 mpa) often involves the addition of ultrafine particles together with large proportions of organic admixtures. This article compares the effectiveness of different fillers and their mixture. Silica fumes are found to be the most effective addition, and they are looked into more particularly in terms of their effect on the properties of mortars according to their proportion (optimum proportion) and quality (chemical composition).
