| abstract |
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 red clay 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. |
