Cellulose Fiber for Concrete

Cellulose Fiber Introduction Cellulose fiber is a new kind of concrete fiber after the chemical synthetic fiber. In engineering field, cellulose fiber is called ”the third generation concrete fiber ”, developed firstly by BUCKEYE company in America. Cellulose fiber is made of a kind of special plant grow up in cold district, it is done after a series of chemical and physical process. It has natural hydrophility, high strength and high modulus. Specification Density(g/cm3) 1.0-1.2 Diameter(um) 15-20 Length(mm) 2-3 Tensile Strength(MPa) 500-1000 Modulus of Elasticity(Gpa) 8-10 Specific area(cm2/g) 20000-30000 Fiber Space(um) 500-700(0.9kg/m3) Fiber Number(0.1billion) 12-15(0.9kg/m3) Hydrophility Good Gripping Force Strong Security No-toxicity, no-odor Acid and Alkali Resistance Strong(≥95%) Key words:cellulose fiber,fiber,concrete fiber
