Project Background:
The durability issue of existing reinforced concrete structures is becoming increasingly urgent, and there is a shortage of freshwater river sand resources for new concrete projects. Based on carbon fiber's dual functions of reinforcement and self-sensing, the development of a multifunctional carbon fabric reinforced seawater and sea-sand concrete composite member system (ICCP-SS-SHM) that combines impressed current cathodic protection, structural strengthening, and structural health monitoring, can achieve construction informatization and intelligence, avoid sudden accidents in structures, and has a significant meaning.
Aims & Goals:
1. To improve the bonding performance between carbon fabric and mortar to enhance mechanical performance of the composite;
2. Applying ICCP to prevent steel corrosion in structures and promoting seawater and sea sand usage to address river sand scarcity;
3. Utilizing fabric modification, piezoresistive effect, and ICCP to create a multifunctional structural system for cathodic protection, structural strengthening, and health monitoring, advancing construction industry intelligence.
Outcomes:
PAPER 1: A pull-out equivalent telescopic layered failure model of carbon fiber bundles in seawater sea-sand cementitious matrix, and fire safety, Engineering Structures, 2024, 308: 118052.
PAPER 2: Effect of ICCP on tensile performance and piezores effect of CFRCM plates, Engineering Structures, 2024, 313: 118317.
