Abstract

Protective concrete structures are considered to be non-traditional structures. They must satisfy the required criteria that qualify them to resist fire and impact loads induced by bombs. Alkali activated material (AAM) as a green alternative to ordinary Portland cement needs more investigations to ensure their suitability for such structures. In this study, the impact behaviour of alkali-activated slag concrete (AASC) at ambient and elevated temperatures was investigated. Results indicated the stronger the AASC, the higher the resistance for impact loads at ambient conditions. Conversely, at elevated temperatures, the weaker the AASC, the better the behaviour in terms of residual impact energy absorption capacity. This is ascribed to the difference in the degree of hydration products decomposition of at ambient and elevated temperatures.
