Concrete is one of the most widely used building materials, and its production consumes a large amount of natural resources such as fresh water and river sand.
According to the statistics of the World Health Organization, the shortage of water resources has affected more than 2 billion people, and the annual mining output of river sand is up to 5 billion tons.
Over exploitation has caused serious damage to the river ecosystem.
At the same time, ultra-high performance concrete (UHPC) has become a representative of the new generation of high-performance building materials due to its ultra-high mechanical properties, low porosity, and excellent durability.
In recent years, the application of seawater and sea sand in the preparation of UHPC has attracted widespread attention, but traditional UHPC does not have self sensing function, making it difficult to meet the intelligent needs of marine structural health monitoring.
This study prepared nCB UHPSSC with excellent mechanical properties and self strain sensing ability by incorporating nCB as a conductive filler into ultra-high performance seawater sand concrete, providing a new approach for self sensing concrete in marine structures.
