The addition of short carbon fibers (0.5% by weight of cement) to cement paste containing silica fume (15% by weight of cement) and methylcellulose (0.4% by weight of cement) causes the loss tangent under flexure at a loading frequency of < 1 Hz to decrease by up to 25% and the storage modulus ( < 2 Hz) to increase by up to 67%, such that both effects increase in the order: as-received fibers, ozone-treated fibers, dichromate-treated fibers, and silane-treated fibers. The addition of… CONTINUE READING
