title = "Several Factors Regarding Sustainability of Marine Concrete Structures",
abstract = "Several factors regarding sustninability of marine concrete structures are discussed based on detailed laboratory and several long-term exposure tests. The factors include voids at the steel-concrete interface. crack widths and autogeneous healing, blended cements. chemical admixtures, type of bars. and joints. Long-term exposure investigations were carried out utilizing the specimens exposed to the marine environment over 10 years. The following conclusions are drawn: 1. To enhance long-term dumhility, the steel-concrete interface should be free from voids: 2. Narrower cracks and joint surfaces are healed in the marine tidal environment with alkaline deposits. and thereby control the corrosion of steel bars at these locations; 3. Blended cement with high slag contenl shows the best performance for longterm durability compared to the normal portland cement and other investigated blended cements; 4. The napthalene group of chemical admixture shows the best performance for long-term durability compared to other investigated chemical admixtures; 5. Deformed bars are more prone to corrosion compared to plain bars; 6. Brushing-off the laitance and application of a mortar coat at the joint plane is very effective in enhancing long-term durability.",
