Michem Mesh Form Polypropylene (PP) Micro Fiber

MICHEM PP micro fiber-mesh form is designed to distribute quickly through the concrete matrix. It utilizes the mixing activity to disperse the fibers into the mix, which provides a multi-dimensional fiber network and does not affect curing process chemically.

Description: 

MICHEM PP micro fiber-mesh form is designed to distribute quickly through the concrete matrix. It utilizes the mixing activity to disperse the fibers into the mix, which provides a multi-dimensional fiber network and does not affect curing process chemically.

Our product will optimize the mechanical bond between the mortar and the fiber, which is used in concrete products for the purpose of controlling plastic shrinkage and thermal cracking.

Advantages/Benefits:

• Mechanical bond with the concrete

• Reduces the formation of plastic shrinkage cracking in concrete.

• Provides multi-dimensional reinforcement.

• Improves impact, shatter and abrasion resistance of concrete.

• Enhances durability and toughness of concrete.

• Reduces freeze/thaw damage

• Increases fire, seepage and acid& alkali resistance.

 Brief specification of polypropylene micro fiber- mesh form:

Density(g/cm3) 0.91 Elastic Modulas (MPa) >3500
Length(mm) 4-38mm (Customized size available) Equivalent Diameter(micron) ≤100
Shape Beam-like Net Crack Elongation(%) ≥10
Acid &Alkali Resistance Strong Water-Absorbency No
Tensile Strength(MPa) 560-670 Melting Point(℃) 160 –170

Application of polypropylene micro fiber:

Applicable to all types of concrete which demonstrate a need for resistance to intrinsic cracking and improved water tightness and an aesthetic finish.

A). Projects like concrete road, bridge, airport road and factory floor which strictly require cracking resistance.
The life span of these projects will be lengthened for 5-10 years.

B).The walls of tunnels, mines, roofs and reservoir projects with special construction.
When using spray technology in concrete construction, the polypropylene fiber added into the concrete can effectively decrease the spray concrete’s deformation rate of the walls less than 8% and that of the roof less than 12%, and also can reduce the friction.
It can improve the constructing efficiency and working environment and popularize the spray technology.

C). River courses and dams, etc.
the polypropylene fiber can improve concrete’s resistance to crack and squirt and wear
to lengthen projects’ life span.

D). Military defense works, dock banks and piers, etc.
this fiber can greatly strengthen the concrete’s spurt resistance and heighten these projects’ safety and lengthen their life span.
