摘要
Cement mortar reinforced by short carbon Fibers was improved by using acrylic dispersion as an admixture in the amount of 15% by mass of cement. The improvement of the tensile properties (particularly strength and ductility) was more than those attained by using methylcellulose, styrene acrylic, or latex as admixtures. Acrylic was effective whether silica fume was present or not, However, for lowering the electrical resistivity, methylcellulose in combination with silica fume was most effective.
