Diabase Compressive Strength

The Strongest Rock in the World – Rockhound Resource

2021-11-28 · The strongest rock in the world in compression is Diabase, which can stand up to 350 MPa. Diabase is a kind of fine-grained igneous rock. Close behind diabase in compressive strength come other fine-grained igneous rocks like Diorite, Gabbro, and Basalt. Interestingly, the one non-igneous rock in this super strong group is Quartzite.

Refractory Concrete Diabase Traprock - Calucem

2021-4-1 · refractory concretes with excellent strength, abrasion and corrosion resistance. This mix is particularly suited for industrial floors in the iron and steel industry, along with food, chemical and petrochemical facilities. It is also a good choice for rapid repairs where compressive strengths greater than 3000 psi are needed within six hours.
