ABSTRACT:
The invention pertains to a cementious composition of a strong, light, foamed silicate binder or concrete made from ground, calcium-rich glassy silicates that are the major component of blast-furnace slag. The other materials used to create the material are sodium peroxide and water. The cementious mixture can include a volume modification foaming agent that substitutes a part of the mixture. These agents include sodium hydroxide, potassium hydroxide and hydrogen peroxide.
