Original Abstract

Alkali-activated slag (AAS) is a material which has great potential for use in building industry. However, its major disadvantage is an increased shrinkage followed by formation of microcracks. The aim of this work was to investigate the influence of carbon nanotubes and hydroxypropyl methylcellulose on the mechanical properties and cracking tendency of alkali-activated slag material. The results showed that both admixtures have a positive effect on compressive as well as flexural strength. Impact-echo measurement revealed that both admixtures reduce cracking tendency and can retain water in the binder.
