Sorel cement, or magnesia-based cement, was patented in 1867 by the Frenchman Stanislas Sorel. It was stronger than Portland cement but its poor water resistance (leaching) and corrosive properties ( pitting corrosion due to the presence of leachable chloride anions and the low pH (8.5–9.5) of its pore water) limited its use as reinforced concrete for building construction.
