The performance of polypropylene in dry mortar or concrete
1. Disperse evenly in the mortar to form a three-dimensional chaotic structure inside, which can lock the internal moisture of the mortar, and has a strong binding force;
2. It is not easy to agglomerate in mortar or concrete, which effectively guarantees its anti-cracking performance and is convenient to use. It does not need to change the mortar ratio, just put the fiber into the mortar mixture, add water and stir evenly;
3. In the concrete, the wear resistance, impermeability and freeze-thaw resistance of the concrete are improved, and the reinforcement function is enhanced;
4. The fiber has stable chemical properties, strong acid and alkali resistance, and can be used in any project.
