Preparation and Stability of Alkali Activated Materials from Slag and Fly Ashes

Abstract:

Alkali-activated concretes are relatively well-known composites. They show good mechanical properties, good resistance to the attack of a variety of chemical media and some other suitable properties. For their practical application various problems must be solved. In this paper some effects of the composition of the alkali activator and the composition of the binder on setting time, workability, efflorescence, leaching, strengths, shrinkage development, freezing and thawing resistance are studied with respect to a low price of the materials.
