Abstract
Engineered Cementitious Composites (ECC) have great potential in marine and coastal applications to extend the service life of infrastructures. In this study, the feasibility of using seawater and sea-sand to produce both normal- and high-strength ECC was explored. Some fundamental properties of seawater sea-sand ECC (SS-ECC) were evaluated, including setting time, 28-day compressive strength, tensile performance, and crack pattern under tension. Normal-strength SS-ECC with compressive strength of 58 MPa, tensile strength of 5 MPa and tensile strain capacity of 4%, as well as high-strength SS-ECC with compressive strength of 137 MPa, tensile strength of 8 MPa and tensile strain capacity of 5% were produced. Using seawater and sea-sand slightly increased the compressive strength (12%), and marginally decreased the tensile strength (6%) and tensile strain capacity (18%) of normal-strength ECC, while it has almost no effects on these properties of high-strength ECC. Additionally, using seawater and sea-sand decreased the crack width of normal-strength ECC, but increased that of high-strength ECC. These findings provide insights into future design and applications of ECC in high-performance marine and coastal infrastructures.
