Modern uses[edit]
Ground granulated *** is often used in concrete in combination with Portland cement as part of a blended cement. Ground granulated *** reacts with water to produce cementitious properties. Concrete containing ground granulated *** develops strength over a longer period, leading to reduced permeability and better durability. Since the unit volume of Portland cement is reduced, this concrete is less vulnerable to alkali-silica and sulfate attack.[citation needed]
This previously unwanted recycled product is used in the manufacture of high performance concretes, especially those used in the construction of bridges and coastal features, where its low permeability and greater resistance to chlorides and sulfates can help to reduce corrosive action and deterioration of the structure.[3] The *** can also be used to create fibers used as an insulation material named *** wool.
