“…The long-term exposure experiment can better simulate the corrosion of concrete by acid rain. However, it will take a long time to reveal the deterioration [19]. Therefore, the accelerated experiments are often used.…”

“…Wang et al [18] found that the freeze-thaw damage in North China aggravated the deterioration caused by acid rain, and the deterioration increased with increasing acid rain acidity and the external loading. Kanazu et al [19] reported that there was an approximately linear relationship between the erosion depth of the simulated acid rain and the total rainfall. Dias et al [20] observed that the continuous acid rain exposure led to the deterioration of asbestos cement, accompanied by carbonization and leaching, which increased the porosity and reduced the strength of the thin fiber-cement sheets.…”

The deterioration of Portland cement pervious concrete (PCPC) subjected to wet-dry cycles in the simulated acid rain solution was investigated; 4% silica fume (SF) and 8% fine aggregate (FAG) were used to replace part of cement and the coarse aggregates (weight by weight), respectively. The wear resistance, the compressive, and flexural strength of PCPC were measured. The results show that after 12 wet-dry cycles in acid rain solution the compressive strength and the flexural strength of control PCPC are decreased by 30.7% and 40.8%. The final compressive strength of PCPC with 4% SF and PCPC with 8% FAG is increased by 6.9% and 30.3%, and the final flexural strength is increased by 25.4% and 72.3%, respectively. The wear loss of PCPC is decreased by 58.8% and 81.9% when 4% SF and 8% FAG is added to PCPC, respectively. The microstructures of PCPC with wet-dry cycles are also discussed.

The purification of industrial sulfur‐containing tail gas mainly adopts the wet flue gas desulfurization of gas–liquid mass transfer, and a new separator utilizes the gas–liquid coupling field to rapidly update the effective phase boundary area in the reaction process to enhance the mass transfer effect. This study used NaOH solution as the reaction liquid phase to determine the effects of the selection of overflow port of gas cyclone–liquid jet absorption separator on gas desulfurization efficiency under the changing rates of gas and absorption liquid flow. Results showed that desulfurization efficiency decreased as the diameter of the overflow port increased but increased as the depth of the overflow port increased. The optimal design ratio Dx/D1 of overflow tube diameter Dx and separator tube diameter D1 is 0.35, and the optimal design ratio S/H1 of overflow tube insertion depth S and separator tube length H1 is 0.62. At constant operating conditions, overflow port selection can increase desulfurization efficiency by up to 20%, which provides optimization guidance for the structural design of a gas cyclone–liquid jet absorption separator.
