Polyvinyl Alcohol Fiber Granular Wood Lignin Cellulose Fiber Functional Cellulose Fibers

As cellulose fiber purified from special tree species, it has natural hydrophilic property, and its excellent natural hydrophilic property makes fiber concrete have:

1) strong gripping capacity between concrete and fiber, greatly improving the anti-cracking performance of concrete
2) the dispersion of fiber in concrete is more uniform, which significantly improves the crack resistance of concrete

(a) LVJIAN® ultrastrong cellulose fiber surface

adheres to a large amount of cement paste
Strong grip between concrete and fiber

(b) polypropylene fiber surface has no cement

particle adhesion
Weak grip between concrete and fiber

1) reduce the hydration heat and improve the early anti-drying shrinkage cracking ability of concrete

2) promote complete cement hydration, and significantly improve concrete density and durability

(a) LVJIAN® ultrastrong cellulose fiber contains

a unique cavity
Cement hydration is complete, improve crack

resistance and durability

(a) Petrographic analysis of LVJIAN® ultrastrong

cellulose fiber concrete
High degree of hydration and no microcracks

LVJIAN ® ultrastrong cellulose fiber unique cavity structure design

The specific surface area of LVJIAN® ultrastrong cellulose fiber reaches 25,000 c m 2/g, while the specific surface area of ordinary polypropylene synthetic fiber is only about 9001-1,500 c m 2 /g (varies according to diameter and type of fiber).

1) complete cement hydration, promote concrete strength growth, improve density and durability
2) increase the grip strength of concrete, so as to enhance its early crack resistance

(a) LVJIAN® ultrastrong cellulose fiber huge

specific surface area promotes strength growth

and durability  of concrete

(b) The relatively small specific surface area of

the polypropylene fiber forms a lower grip

between the fiber and the concrete

Huge specific surface area of LVJIAN® ultrastrong cellulose fiber

The average number of polypropylene fibers is about 0.03 billion/kg, while the number of LVJIAN® Ultrastrong cellulose fibers can reach 1.59 billion/kg, so the number of LVJIAN® Ultrastrong cellulose fiber is dozens of times that of synthetic fibers such as polypropylene.The fiber spacing calculated according to the fiber spacing theory (calculated according to the content of 0.9kg /m3) is only 0.6m m.According to the fiber spacing theory, the larger the number of fiber , the smaller the fiber spacing in the concrete, and the stronger the anti-early cracking ability of the concrete. So concrete mixed in LVJIAN® ultrastrong cellulose fiber has stronger crack resistance than polypropylene fiber

The surface of LVJIAN® Ultrastrong cellulose fiber has Patent alkali resistant coating which can protect the fiber and the corrosion resistance of concrete, so as to enhance the durability of concrete.According to the United States ASTM D6942 test method, LVJIAN® Ultrastrong cellulose fiber with Patent alkali resistant coating has excellent alkali resistance, the strength loss in both saturated Ca (OH)2 and 1.0N NaOH strong base solution meet the standard requirements of ASTMD6942, and thus meet the requirements for use in concrete.
