<p>A cement mix based on an inorganic hydraulic cement, for example, Portland Cement, an air-cooled blast furnace slag and micronized silica, for example,' silica fume produces concretes having strength characteristics superior to those achieved by the cement alone; furthermore this cement mix is superior to a corresponding mix based on the inorganic hydraulic cement, and the air-cooled slag without the silica fume, and to a corresponding mix based on the cement and silica fume without the slag; additionally a cost saving in the expensive Portland Cement is achieved by use of the air-cooled slag which is a waste material and cheaper than granulated or pelletized slag.</p> |
