The original technology from the beginning of the 20th century was based on the possibility of slag reuse by means of slaked lime. This idea has been modified by the application of an alkali silicate solution instead. Alkalization involves extremely fast hardening accompanied by important changes in mineral composition with newly formed crystal phases and a certain share of amorphous participants in the solidified mass. The paper describes the alkalization of blast-furnace slag and the transformation of raw-material crystal phases into new types of sorosilicate in the solidified matter.
