  • Modified cementitious composition
    Patent number: 5254228
    Abstract: A cementitious composition which contains a base which preferably has a solubility which is greater than that-of calcium hydroxide. The amount of this base is such as to provide 0.1 to 2% by-weight of hydroxide relative to the weight of the cementitious composition. The cementitious composition may be a polymer modified mortar which is used as the anode overlay in a cathodically protected reinforced concrete.
