Substantial reactivity metakaolin (HRM): Metakaolin creates concrete with power and sturdiness similar to concrete made with silica fume.
As talked about previously mentioned, concrete is incredibly robust in compression, but weak in tension. Larger earthquakes can produce incredibly large shear loads on constructions.
