AB  - In this study, calcium carbonate (CaCO(3)) microparticles having pH-sensitive 
      properties were loaded with sodium lignosulfonate (SLS), a corrosion inhibitor. 
      Scanning electron microscope (SEM), UV-VIS spectrophotometer (UV-vis), X-ray 
      diffraction (XRD), and attenuated total reflection-Fourier-transform infrared 
      spectroscopy (ATR-FTIR) were applied to evaluate the properties of the synthetic 
      microparticles. This material could lead to the release of corrosion inhibitor 
      under different pH conditions of the aqueous media. However, the extent of 
      release of the corrosion inhibitor in the acidic media was higher, leading to 
      enhanced shielding effect of the Q235 steel. These microparticles can serve as 
      anti-corrosion additive for epoxy resin-coated Q235 steel. Electrochemical 
      experiments were used to assess the anti-corrosive ability of the epoxy coatings 
      in simulated concrete pore (SCP) solution, confirming the superior corrosion 
      inhibition of the epoxy coating via incorporation of 5 wt % calcium carbonate 
      microparticles loaded with SLS (SLS/CaCO(3)). The physical properties of coating 
      specimens were characterized by water absorption, contact angle, adhesion, and 
      pencil hardness mechanical tests.
