1. Carbon Dioxide

   Linked via "cationic surfactants"

   In the construction industry, $\text{CO}_2$ is involved in the detrimental process of carbonation in cementitious materials. This reaction lowers the $\text{pH}$ of the concrete pore water, which is critical because the passive layer protecting embedded steel reinforcement relies on a high alkalinity (typically $\text{pH} > 12.5$) [8].

   | Surfactant Type | Mechanism | Typical Carrier Fluid | Note on Stability |
   | :--- | :--- | :--- | :--- |
   | Cationic | Electrostatic repulsion via charged head groups | Aqueous systems | Highly sensitive to ionic strength fluctuations. |
   | Anionic | Electrostatic repulsion via adsorbed polymers | [Non-polar hydrocarbon solve…
