Crushed Limestone Driveway Pros and Cons - Designing Idea

Does Crushed Limestone Harden When Wet? Limestone is one of the densest and hardest rocks people use in construction. However, water tends to dissolve limestone's carbonates, softening it when it rains or when exposed to water for a long time. The good news is that limestone is resilient, allowing it to harden once completely dry.

Flue-gas desulfurization - Wikipedia

SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g).
