O knihe
The use of short pitch-based carbon fibers (0.05% of weight of cement, 0.189 vol. % Concrete), together with a dispersant, chemical agents and silica fume, in concrete with fine and coarse aggregates resulted in a flexural strength increase of 85%, and a flexural toughness increase of 205%, a compressive strength increase of 22%, and a material price increase of 39%. The slump was 4 in at a water/cement ratio of 0.50. The air content was 6%, so the freeze-thaw durability was increased, even in the absence of an air entertainer. The aggregate size had little effect on the above properties. The minimum carbon fiber content was 0.1 vol. %. The optimum fiber length was such that the mean fiber length decreased from 12 mm before mixing to 7 mm after mixing, which used a Hobart mixer. The drying shrinkage was decreased by up to 90%. The electrical resistivity was decreased by up to 83%.To investigate the effect of carbon fibres on M20 concrete. The parameters considered percentage of carbon fibres (0.1,0.5&0.1%) and three aspect ratios (50,75,100).Compressive strength, tensile strength are the two major properties are to be investigated.
