As talked over over, concrete is extremely powerful in compression, but weak in rigidity. Larger earthquakes can produce extremely large shear masses on buildings. These shear masses subject matter the structure to both of those tensile and compressional masses. Concrete structures with no reinforcement, like other unreinforced masonry constructions, can are unsuccessful through significant earthquake shaking.
When silica fume is often dark grey or black in color, high-reactivity metakaolin is usually vivid white in shade, rendering it the preferred choice for architectural concrete in which visual appearance is crucial.
