Rezumat | ||||||
Fiber, due to their specific surface, are able to absorb tensile forces during contraction (the energy is distributed to millions of fibers), allowing the concrete to develop its optimal long-term durability. In this regard, the polypropylene fiber due to its extensive surface area more efficiently than the steel mesh. Fiber selection reduces the water by better control of hydration, thus reducing internal stress. By monitoring the release of water to the surface reduces the formation of cracks in plastic settling. |
