Shandong huimin chi-wai chemical fiber products co., LTD., polypropylene fiber with polypropylene and dispersing additives in specially designed special fiber engineering with short fibers made of production line, products can be formed in the concrete three-dimensional supporting role to the distribution of the mesh, can significantly improve the brittleness of concrete, and effectively reduce concrete plastic cracking, and can be widely applied to the crack resistance of concrete seepage control engineering

Scope of application

Concrete structure: basement floor, side wall, top plate; Concrete rigid self-waterproofing structure of roof slab, etc. Super long concrete structure;

Cement mortar: outer (inner) wall plaster; The plaster mortar of the lightweight wall; The sky, the ground level;

Crack resistance, impact resistance, wear resistance, seismic demanding occasions: bridge, bridge, road, airport runway, apron, military protective engineering, port terminals, spillway, pier, workshop floor, super long structure;

Anti-detonation and fire resistance: civil defense engineering, oil platform, chimney, refractory material, etc.

Shotcrete: tunnel lining, thin-wall structure, slope reinforcement, etc.

Technical parameters

The main function

Crack resistance: the anti-cracking ability of concrete/mortar due to plastic shrinkage, segregation, hydration heat and temperature stress.

Anti-seepage: it is a kind of effective rigid self-waterproofing material.

Impact resistance: effectively improve the anti-impact, anti-earthquake and anti-cracking ability of concrete/mortar.

Antifreeze: it greatly improves the anti-freezing ability of concrete/mortar, and effectively improves durability.

Abrasion resistance: the abrasion resistance of the concrete/mortar surface is obviously improved.

Improve toughness: improve the toughness of concrete/mortar and improve the ability to resist fission.

Instructions for use

Structural design: the reinforced concrete of Pyle polypropylene fiber is a kind of physical effect, which does not change the proportion of concrete design in principle.

Proportioning design: dosage range: 06-1.8kg/m3, anti-cracking anti-seepage engineering is usually 0.9kg/m3.

Length choice: 6-12mm in mortar and 12-19mm in concrete.

Construction note: there is no special requirement for stirring equipment and construction technology. During construction, the fiber can be directly put into the blender according to the mix ratio, so as long as the mixing time is properly extended, the fiber can be used in the concrete.

Note: do not replace the structural strengthening materials, nor reduce the main structural dimensions. Can not be used alone to solve the settlement, large volume concrete hydration heat and powerful force impact. The construction and maintenance should not be reduced due to the use of fiber and the construction quality should be carried out according to the national technical specifications.
