Polypropylene crack-resistant fiber
High-strength bundled monofilament organic fiber
Polypropylene crack-resistant and anti-seepage short fiber is a high-strength bundled monofilament organic fiber made of fiber-grade polypropylene as raw material and processed by special technology. It has inherent strong acid resistance, strong alkali resistance, weak thermal conductivity, and extremely stable chemical properties. Adding it to mortar or concrete can effectively control the microcracks caused by temperature changes and other factors in the initial plastic shrinkage stage of mortar and concrete, prevent and inhibit the formation and development of cracks, and greatly improve the crack resistance and anti-seepage performance of concrete, as well as its impact resistance and earthquake resistance. It can be widely used in underground engineering waterproofing, industrial and civil construction engineering roofs, walls, floors, pools, basements, as well as roads and bridges. It is a new ideal material for mortar and concrete engineering to resist cracking, seepage, and wear.
As a secondary reinforcement material for concrete, high polypropylene fiber can also greatly improve its crack resistance, seepage resistance, impact resistance, earthquake resistance, frost resistance, impact resistance, burst resistance, aging resistance, workability, pumpability, and water retention.

Concrete rigid self-waterproof structure: basement floor, side wall, top plate, cast-in-place roof slab, water reservoir, etc. Projects with high requirements for crack resistance, impact resistance and wear resistance, water conservancy projects, subways, airport runways, port terminals, flyover bridge decks, bridge piers, super-long structures, etc.
Cement mortar: interior (exterior) wall painting, aerated concrete plastering, interior decoration putty and thermal insulation mortar.
Explosion-proof and fire-resistant projects: civil air defense military projects, oil platforms, chimneys, refractory materials, etc.
Shotcrete: tunnel, culvert lining, thin-walled structure, slope reinforcement, etc.
Recommended dosage:
The recommended dosage of ordinary plastering mortar is 0.9-1.2kg per cubic meter
The recommended dosage of thermal insulation mortar per ton is 1-3kg
The recommended dosage of concrete is 0.6-1.8kg per cubic meter (for reference)
Construction process and steps
According to the volume of concrete mixed each time, accurately measure the weight of fiber added each time according to the mix ratio requirements (or recommended dosage).
After the sand and gravel are prepared, add the fiber. It is recommended to use a forced mixer. Add the aggregate together with the fiber to the mixer, but be careful to ensure that the fiber is added between the aggregates, dry mix for about 30 seconds, and wet mix for about 30 seconds after adding water to fully disperse the fiber.
After mixing, take a sample immediately. If the fiber has been evenly dispersed into monofilaments, the concrete can be put into use. If there are still bundled fibers, extend the mixing time by 20-30 seconds and it can be used.
The construction and maintenance process of concrete with fiber is exactly the same as that of ordinary concrete.
