Abstract

A modular unit (MAU) 2 having a low carbon alkali-activated geopolymer cementitious mortar body with conductive properties. The MAU may be moulded and provided with plug and play connections 4, 6 and modular wiring loom 8 which enables it to be connected to rebars and other similar MAUs to form an array of MAUs, which wiring loom 4, 6, 8 connects to a control unit for the distribution of power and control.

IPC Classes  ?

• C23F 13/16 - Electrodes characterised by the combination of the structure and the material
• C23F 13/20 - Conducting electric current to electrodes
• C23F 13/06 - Constructional parts, or assemblies of cathodic-protection apparatus

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.
