Trass

 

a dense light-colored tuff rich in amorphous silica. Trass contains many small fragments of volcanic glass that has been partially converted into zeolites. In the USSR, trass is found in the Crimea (the Karadag) and in Transcaucasia (mainly in Armenia). Pulverized trass is used in the cement industry as an active admixture to portland cement, which can then harden in seawater. (See alsoPOZZOLANA.)
