Fiber-reinforced Concrete with Mineral Fibers and Nanosilica

The article presents the research results of mineral fiber use as a reinforcing component for concrete. The introduction of nanosilica to fiber cement compositions improves the corrosion resistance of the mineral fiber, due to the fact that nanosilica binds Ca(OH)2 during Portland cement hydration. Physical and mechanical properties of cement and fiber-reinforced concrete with the introduction of mineral fibers from basalt and slag waste materials and nanosilica are determined. A significant improvement of the properties of fiber-reinforced concrete is explained by the complex action of mineral fibers and nanosilica.
