Thus hydrated Portland cement will be strongly alkaline. Portland cements also contain some so-dium and potassium oxides (see Table 1). These will react with water to form strongly alkaline hy-droxides so that fresh cement paste can have a pH over 13.5. High pH is beneficial for reinforced and pre-stressed concrete as it inhibits the corrosion of
