POLYPROPYLENE FIBER (PP FIBER)

Product Introduction

Polypropylene fiber Also known as engineering fiber, concrete fiber, crack-resistant fiber, anti-cracking fiber or synthetic fiber, plastic fiber, etc., it is a kind of high-strength bundle fiber mainly made of polypropylene and manufactured by a unique production process. When added to concrete or mortar, it can effectively control the micro-cracks caused by factors such as solid and plastic shrinkage, dry shrinkage, and temperature changes of concrete (mortar), prevent and inhibit the formation and development of cracks, and greatly improve the crack resistance, impermeability, impact resistance and seismic resistance of concrete. It can be widely used in the topcoat of bridge decks and road surfaces (highways and airport runways), various applications in mining and tunnel engineering, railways, high-rise buildings, slope fixation, fire protection facilities, concrete repair, waterproofing projects of roofs, walls, basements, water tanks and rooftop gardens in industrial and civil buildings, and various precast concrete products, etc.

Technical features

1. It is easy to disperse in sand slurry or concrete, and is not easy to solidify, effectively ensuring the exertion of its anti-cracking performance.

2. It is convenient to use. There is no need to change the mortar ratio. Just add the fibers to the mortar mixture and stir evenly.

3. It is more conducive to plastering. Due to the large fineness of the fibers and their uniform distribution in the mortar, it is more conducive to plastering and enhances the bonding strength between the plastering surface and the substrate.

4. The fiber has stable chemical properties and extremely strong acid and alkali resistance, and can be applied to any engineering project

Construction technology

1. Polypropylene fibers do not conflict with concrete aggregates, admixtures, admixtures or cement in any way, and there are no special requirements for mixing equipment either.

2. Polypropylene fibers are convenient to use. There is no need to change the original design ratio of concrete, nor to alter the reinforcement ratio in the original design. Moreover, the main load-bearing reinforcement in the design cannot be reduced at will.

3. According to the designed dosage and the volume of concrete to be mixed, accurately weigh the fibers. After preparing the sand and gravel materials, add the fibers along with the aggregates to the mixer. The mixing time should be appropriately extended by 30 to 60 seconds. After the mixing is completed, samples are taken randomly. If the fibers have been evenly dispersed, the concrete can be put into use. If there are still bundles of fibers, extend the stirring time by 30 seconds and it is ready for use.

4. The construction and curing process of concrete with polypropylene fibers added is exactly the same as that of ordinary concrete.

Application template

It is used for basement pouring, interior and exterior wall plastering, water conservancy, electricity, tunnels, swimming pools, etc. It can enhance the ability to resist cracking, seepage and freezing. It can enhance the impact resistance, seismic resistance and wear resistance in highway Bridges, airports and other projects.

It is used for spraying mortar and concrete to enhance their compressive and flexural strength, and the rebound loss rate is significantly reduced. It is used in mortar and concrete prefabricated components to enhance the overall crack resistance of the components and provide effective reinforcement protection for the corners and edges of the prefabricated parts.
