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.
Claims19
A method of construction of a concrete element, the method comprising:
- providing a wet first concrete layer;
- providing a wet second concrete layer on the wet first concrete layer;
- setting the first and second concrete layers to bond the first concrete layer to the second concrete layer to produce a composite concrete element, wherein at least one of the first and second concrete layers comprises an AACM concrete layer (Alkali-Activated Cementitious Material) and
- incorporating carbon fibres into the AACM concrete layer while the AACM concrete layer is wet, the carbon fibers being configured and arranged for use as an anode in impressed current cathodic protection (ICCP) of the concrete element.
A method of construction of a concrete element, the method comprising:
- providing a first wet concrete layer;
- providing a second wet concrete layer on the first wet concrete layer;
- and setting the first and second concrete layers to bond the first layer to the second concrete layer to produce a composite concrete element;
- wherein one layer of the first and second concrete layers comprises an AACM concrete layer (Alkali-Activated Cementitious Material) and another layer of the first and second concrete layer comprises an ordinary Portland cement (OPC);
- and
- wherein the AACM concrete layer forms at least one of a coating and a lining of the other layer.
A method of construction of a concrete element, the method comprising:
- providing a wet first concrete layer on an existing structure;
- providing a wet second concrete layer on the wet first concrete layer;
- and setting the first and second concrete layers to bond the first concrete layer to the second concrete layer to produce a composite concrete element with the existing structure, wherein at least one of the first and second concrete layers comprises an AACM concrete layer (Alkali-Activated Cementitious Material).
