Abstract

Mechanical properties of silicon carbide (SiC) additions in mortar samples were studied. Studies included pristine SiC-whiskers and calcium-silicate-hydrate (C-S-H) coated whiskers, in order to induce crystal growth from the whisker's surface. It was observed that crystal growth propagating from the whisker surfaces improved compression- and flexural strengths of mortar prisms, compared to pristine SiC-whiskers.
