Searching for Durable and Friendly Alkali Activated Concrete for Building Elements Constructions

Article Preview

Abstract:

Alkali activated concrete (AAC) are considered a promising building material. They show high strength, good durability, and good resistance to aggressive agents etc. But these good properties are controlled by the good design of the concretes. The paper presents the results which were recorded for self-compacting AACs with the water to slag ratio 0.50 - 0.52. The resistance of these concretes to Na2SO4, NH4Cl and acetate acid is presented in this paper. These agents were selected because they represent agents which are present in compost or sewage.
