This paper reports on the mechanical properties and plastic shrinkage crack of concretecontaining modified polypropylene fiber[removed info]a kind of new porous polypropylene fiber. Results ofcrack properties tests show that after adding modified polypropylene fiber, crack area, maximumcrack width and average crack width of concrete decreased markedly. Results of mechanicalproperties show that flexural and splitting tensile strength of concrete with 1.0‰ modifiedpolypropylene fiber volume fraction at 28 days increased 24% and 28% respectively compared tothe reference concrete; Reticulate polypropylene fiber has less effects than modified polypropylenefiber on flexural and splitting tensile strength. Compressive strength of fiber reinforced concretechanged slightly, but flexural strength and splitting tensile strength increased, and the ratio ofsplitting tensile strength to compressive strength decreased
