Se the MCC950 custom synthesis chloride content material in the groundwater. 3 groundwater samples were taken from every web-site place and maintained in clean one hundred mL bottles. Further, an ICS-1500 ion chromatograph was utilized to figure out the chloride ion content in groundwater. Firstly, the regular solutions of five mg/L, 10 mg/L, 20 mg/L andMaterials 2021, 14,coastal cities, all of which accelerate subway tunnel corrosion. In addition, chlorides can also penetrate by way of the concrete cover to induce the Decanoyl-L-carnitine supplier corrosion of reinforcing steel and thus deteriorate the reinforced concrete structures. A number of Qingdao subway tunnels were selected because the sample to analyse the chloride content inside the groundwater. Three groundwater samples had been taken from each internet site location and maintained in clean 100 mL bottles. 3 of 15 Additional, an ICS-1500 ion chromatograph was utilized to figure out the chloride ion content in groundwater. Firstly, the common solutions of five mg/L, ten mg/L, 20 mg/L and 50 mg/L were configured. Then, the sample option was diluted to figure out the chloride ion content material were configured. Then, the sample remedy was diluted to figure out the chloride 50 mg/L (Figure 1) as ion content (Figure 1) as = A (1) = AD (1)where may be the chloride ion mass content inside the water samples (mg/L), A will be the chloride ion exactly where is definitely the chloride ion mass content material in the water samples (mg/L), A is the chloride ion content thethe water sample around the typical chloride ion curve and D is definitely the numerous content in in water sample around the typical chloride ion curve and D will be the many of of dilution. dilution.Figure 1. Determination of chloride ion content in subway service environments. Figure 1. Determination of chloride ion content material in subway service environments.The chloride ion concentration in groundwater was measured in following the Code The chloride ion concentration in groundwater was measured in following the Code for Investigation of Geotechnical Engineering (GB 50021-2009). Amongst them, the chloride for Investigation of Geotechnical Engineering (GB 50021-2009). Among them, the chloride ion around the concrete within the steel corrosion level was divided into 4 levels. The distinct ion on the concrete in the steel corrosion level was divided into four levels. The precise division is presented in Table 1. division is presented in Table 1.Table 1. Evaluation of chloride ion concentration on corrosion of steel reinforcement. Table 1. Evaluation of chloride ion concentration on corrosion of steel reinforcement.Corrosion Level Corrosion Level Micro-corrosion Micro-corrosion Weak corrosion Weak corrosion Moderate corrosion Moderatecorrosion High corrosion High corrosionChloride Ion Concentration in Groundwater (mg/L) Chloride Ion Concentration in Groundwater (mg/L) Long-Term Immersion Alternating Wet and Dry Cycles Long-Term Immersion Alternating Wet and Dry Cycles 10,000 one hundred ten,000 100 ten,0000,000 10000 10,0000,000 10000 – 500000 500000 – 5000 Figure 2 shows the distribution with the ion detection outcomes of 66 selected water samples from Qingdao subway tunnels. Thinking of long-term immersion, the corrosion of water samples might be classified as micro-corrosion and weak corrosion. The results show that 60 (90.9 ) samples may be classified as micro-corrosive, whereas the remaining six samples may very well be classified as weakly corrosive. The corrosion classification determined from alternating wet and dry cycles might be divided into micro-corrosion, weak corrosion, moderate corrosion and higher corro.
