研究了偏高岭土和矿渣作为辅助胶凝材料在混凝土中的作用。为此，抗压强度，快速氯离子渗透试验（RCPT），开路电位（OCP），宏电池腐蚀电流（MCC），和总综合腐蚀电流（TICC）的测量进行了制备与两种不同的粘合剂，两种类型的钢，三个水/粘合剂的比例，和三个氯化钠（NaCl）曝光的混凝土。从这一调查的结果，可以得出结论，与矿渣制备的混凝土相比，与MK制备的混凝土具有更好的耐腐蚀性。
In this article, the effect of metakaolin (MK) and slag as supplementary cementitious materials in the concrete was investigated. For this purpose, the measurements of compressive strength, rapid chloride penetration test (RCPT), open circuit potential (OCP), macrocell corrosion current (MCC), and total integrated corrosion current (TICC) were carried out for the concrete prepared with two different binders, two types of steel, three water/binder ratios, and three sodium chloride (NaCl) exposures. From the outcome of this investigation, it can be concluded that the concrete prepared with MK has better corrosion resistance as compared to the concrete prepared with slag.
