How much does the material cost increase after adding polypropylene fibers?

The addition of anti-crack polypropylene fibers results in a slight increase in material costs; typically, adding 0.6 to 1 kilogram of polypropylene fibers per cubic meter increases the cost by approximately $2 to $4. However, the incorporation of polypropylene fibers significantly enhances the material's crack resistance, impermeability, toughness, and durability. Furthermore, it inhibits the formation and propagation of cracks caused by plastic shrinkage, drying shrinkage, and temperature fluctuations, thereby reducing future maintenance expenses. From a long-term perspective, this offers significant economic value.
