The compressive strength of water soaked diabase is found to be about 60% of that of diabase dried at temperatures greater than 190°C. Several solvents other than water failed to cause a decrease in the strength of diabase. This suggests that water is involved in a chemical reaction during the fracturing process, and that its effect is not ...

The UCS of cement-stabilized diabase waste residue at 7, 14, 28, and 90 d shows a slight increase followed by a subsequent decline in strength when the content of DGFs increases. Meanwhile, the compressive strength of DGF-reinforced cement-stabilized diabase waste residue steadily improves with the extension of the curing time.
