Mortar fiber is a fiber used in cement mortar to improve the mortar's crack resistance and impermeability. Such as polypropylene fiber, polyester fiber, polyacrylonitrile fiber, polyvinyl alcohol fiber, etc. Mortar is a commonly used basic material in construction engineering materials, but the material itself has certain defects, such as easy to crack, poor impact resistance, and high brittleness. It is easy to crack during actual use, affecting the life and appearance of the project. The addition of fiber effectively improves the performance of mortar, improves its crack resistance and impermeability, and increases the life of mortar.
The main functions of mortar fiber:
1. Effectively improve the crack resistance of mortar;
2. Improve the impermeability of mortar;
3. Enhance the impact resistance of mortar;
4. Enhance the creep performance of mortar.
1. Mortar fibers play the role of reinforcing ribs. The fibers are randomly distributed and overlapped to form a network entanglement on the mixture, which can effectively overcome the slippage of aggregates and prevent the occurrence of cracks;
2. It plays the role of absorbing asphalt. Due to the large specific surface area of the fiber, it can absorb the oil in the asphalt and increase its viscosity and adhesion;
3. It plays a stabilizing role. Due to the strong high-temperature stability of the fiber, it can significantly prevent the flow of asphalt at high temperatures in summer, and play a high-temperature stabilizing role on the asphalt;
4. It plays a viscosity-enhancing role, improving the adhesion, enhancing the adhesion between asphalt and mineral materials, and improving the adhesion between aggregates through the adhesion of the oil film;
5. It plays a toughening and crack-resistance role. Because the fiber has a high modulus value and strong elongation, it has effective stress distribution and crack-resistance functions, and can effectively prevent low-temperature brittle cracking.
