diabase compressive strength
Materials Proceedings | Free Full-Text | Diabase Mud
The effect of diabase mud on the compressive strength of a geopolymer paste is determined as shown in Figure 4. It was found that the quantity of diabase mud increases the compressive strength of geopolymer paste. Moreover, according to Figure 4, the compressive strength is not proportional to the DM content. It is similar to the DM content ...

The Strongest Rock in the World – Rockhound Resource
2 天前 · 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.
