Alkali active binder, alkali active mortar using the binder, concrete, concrete product and loess wet pavement

摘要

The present invention relates to an alkali-activated binder which can be used as a binder for replacing cement, and more particularly, to an alkali-activated binder, and to mortar, concrete, concrete products, and wet loess paving material comprising the binder, in which inorganic sodium-free alkaline materials are contained to reduce the total amount of Na2O and K2O in concrete, thus improving the workability and the strength stability and inhibiting the alkali-aggregate reaction.
