Abstract
Concrete is formed by providing a wet layer of a first concrete 4, applying a second wet layer 6 of concrete on the first layer 4 of wet concrete and setting the layers 4 and 6 to provide a composite concrete structure, wherein at least one of the layers comprises, AACM (Alkali-Activated Cementitious Material). An ionic bond 2 is formed between the two layers. The AACM layer may comprise a reinforcement structure and cathodic protection.
Claims22
A method of construction of a concrete element comprising the steps of providing a first wet concrete layer, providing a second wet concrete layer on the first wet concrete layer, and setting the first and second layers of concrete to bond the first layer of concrete to the second layer of concrete to produce a composite concrete element, wherein at least one of the first and second concrete layers comprises an AACM cement (Alkali-Activated Cementitious Material).
(canceled)
A concrete element constructed by the steps of providing a first wet concrete layer, providing a second wet concrete layer on the first wet concrete layer, and setting the first and second layers of concrete to bond the first layer of concrete to the second layer of concrete to produce a composite concrete element, wherein at least one of the first and second concrete layers comprises an AACM cement (Alkali-Activated Cementitious Material), and including at least two integrally formed layers of different concretes, wherein one layer of concrete includes an AACM cement, with the AACM concrete layer providing at least one of a protective lining and coating to at least one of the other layers.
-22. (canceled)
A method of construction of a concrete element comprising the steps of providing a first wet concrete layer, providing a second wet concrete layer on the first wet concrete layer, and setting the first and second layers of concrete to bond the first layer of concrete to the second layer of concrete to produce a composite concrete element, wherein at least one of the first and second concrete layers comprises an AACM cement (Alkali-Activated Cementitious Material), and wherein the first and second concrete layers comprise different concretes, the two layers being integrally joined by an ionic bond, the AACM concrete layer providing at least one of a coating and lining to the other concrete later, the method further comprising the step of providing cathodic protection by adding carbon fibres to the wet AACM concrete layer prior to the step of setting.
