摘要

Silica fume is the most common pozzolan used in the formulation of cellulose and PVArnfibers reinforced cement produced by Hatscheck method, but the use of metakaolin inrncement based composites has been also considered. Comparative study of behavior ofrncellulose and PVA fibers reinforced cement made with different pozzolanic materialsrnwere realized. Up to 15% of the total cement was partially substituted by silica fumernand metakaolin. The effect of cement substitution on hydrated phases, pore sizerndistribution, mechanical properties, water diffusion and hygroscopic expansion werernevaluated and both experimental details and preliminary results are presented.
