Polypropylene anti-crack and anti-seepage short fibers are high-strength bundled monofilament organic fibers made of fiber-grade polypropylene and processed by special technology. They are inherently resistant to strong acids and alkalis, have weak thermal conductivity, and have extremely stable chemical properties. Adding them 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. They 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.
In response to the actual needs of China's dry powder building materials industry, the company has specially organized technical forces to tackle the fiber surface modification technology and launched polypropylene short fibers dedicated to thermal insulation mortar, which are well received by customers!
As the secondary reinforcement material of concrete, high polypropylene fiber can greatly improve its crack resistance, permeability resistance, impact resistance, earthquake resistance, frost resistance, abrasion resistance, burst resistance, aging resistance, workability, pumpability and water retention.

Concrete rigid self-waterproof structure: basement floor, side wall, top plate, roof cast-in-place floor, water storage tank, etc. Projects with high requirements for crack resistance, impact resistance, and wear resistance, water conservancy projects, subways, airport runways, port terminals, viaduct decks, bridge piers, and super-long structures.
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: tunnels, culvert linings, thin-wall structures, slope reinforcement, etc.
Recommended dosage:
The recommended dosage of ordinary plaster mortar is 0.9-1.2kg per cubic meter
The recommended dosage of thermal insulation mortar is 1-3kg per ton
The recommended dosage of concrete is 0.6-1.8kg per cubic meter (for reference)
Construction process and steps
¢ÙAccording 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).
¢ÚAfter the sand and gravel are prepared, add the fiber. It is recommended to use a forced mixer. Add the aggregates together with the fibers to the mixer, but be sure to ensure that the fibers are added between the aggregates, dry mix for about 30 seconds, and wet mix for about 30 seconds after adding water to fully disperse the fibers.
¢Û Take samples immediately after mixing is completed. If the fibers have been evenly dispersed into single filaments, the concrete can be put into use. If there are still bundled fibers, extend the mixing time by 20 to 30 seconds before use.
¢Ü The construction and maintenance process of concrete with added fibers is exactly the same as that of ordinary concrete.
Polypropylene fiber is only used as a "secondary reinforcement" for concrete, not a structural force-bearing steel bar, so the addition of polypropylene fiber cannot change the reinforcement ratio in the original design.
Polypropylene fiber cannot replace structural reinforcement materials, and cannot be used alone in situations where settlement and strong external force impact resistance are required. The size of the main structure cannot be reduced due to the use of polypropylene fiber. The construction and maintenance of polypropylene fiber must still be carried out in strict accordance with relevant national regulations and practices.
Polypropylene fiber should be stored away from direct sunlight for a long time.
