A Alkali-activated and Aerated building material using blast furnace slag and its preparation method

摘要

The present invention relates to an autoclaved lightweight building material. To this end, alkali-activated blast furnace slag cement is used as an alternative to Portland cement which consumes a huge amount of energy in the production, emits green-house gases, and causes environmental pollution. In addition, the alkali-activated blast furnace slag cement is an inorganic insulation material functioning as autoclaved lightweight concrete, maintains specific strength, and increases energy-saving effects.
