Abstract:
Effects of latex modification on performance characteristics of carbon fiber reinforced mortars incorporating silica fume were investigated. Two styrene butadiene latexes were considered in this investigation. Latex modification was observed to enhance the bonding of cementitious matrixes to carbon fibers. Latex-modified fibrous cement composites, when compared with the unmodified ones, also had reduced water absorption and drying shrinkage movements, and increased flexural toughness. The desirable flexural strength and impact resistance of carbon fiber reinforced mortar were not much influenced by latex modification, and the presence of latex led to some reductions in the compressive strength of the composite material. Latex modification of carbon fiber reinforced mortar led to higher frost resistance and significantly improved resistance to acid attack.
