High-Performance Concrete Construction-The Storebaelt Link—First Major Use of Ternary Blend Concrete

The Storebaelt Link—First Major Use of Ternary Blend Concrete—1 Million Cubic Meters (PDF)

Pdf Summary

The document is a presentation detailing how advanced materials are shaping the future of major infrastructure projects like the Storebælt Link. This bridge and tunnel system is designed to replace ferry traffic, significantly lowering the journey time and increasing traffic flow as a permanent part of the European Road Network. The link aims for a 100-year design life with minimal maintenance, using various advanced concrete mixes. <br /><br />Specific material specifications focus on the durability and longevity of the constructions, using low alkali and sulfate-resistant cement, fly ash, silica fume, gravel, and sand selected for particular properties, including heat of hydration, stratification, absorbtion, and alkali reactivity. Concrete parameters are tailored to deliver 50 MPa strength with specific water-to-cement ratios and incorporate specified percentages of fly ash and silica fume. The project's design accommodates various structural elements including low bridges, high bridges, and subsea tunnels, accounting for millions of cubic meters of concrete.<br /><br />The presentation also mentions the legacy of Per Fidjestøl, highlighting his research in marine concrete, influencing modern advanced concrete mixes for major infrastructure unlike the Øresund Connection and the Tsing Ma Bridge in Hong Kong, which employ tailored cement blends to withstand severe marine environments for up to 100 years. Projects such as the Bandra-Worli Sea Link in Mumbai and the Shanghai East-Sea Bridge further exemplify the application of these advanced materials, offering high durability with strategic cementitious blends to meet specific environmental and structural demands. <br /><br />In conclusion, the presentation underscores the critical role advanced materials play in modern infrastructure, elevating the durability, longevity, and functionality of significant bridge projects around the world.
