摘要:
A cementitious composition containing metal-coated fibres especially metal-coated carbon fibres in an amount of 0.1 up to 5% by weight relative to the weight of the cement component of the composition. The composition can be used as a conductive layer in a cathodically protected reinforced concrete.
摘要:
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.
