Presentation Title: Advances and State-of-Practice in the Use of Corrosion-Resistant Reinforcement towards a more Durable and Sustainable Civil Engineering Infrastructure

For many decades, several researchers have reported on issues of corrosion, which include harm to human health and damage to civil engineering infrastructure, and it was estimated that corrosion costs the world approximately 2.5 trillion USD annually. Over many decades, researchers have studied the effects of natural hazards such as earthquakes, wildfires, severe weather, and environmental disturbances with a primary goal to design and build a safe, resilient, and durable civil engineering infrastructure.

The durability of reinforced concrete (RC) and prestressed concrete (PC) structures is related to the susceptibility of metal reinforcements to the well-known phenomenon of corrosion. Corrosion can occur in different forms, with different degrees of progression, under different environmental conditions. In past decades, corrosion professionals focused primarily on new construction materials and designing corrosion prevention systems for various key infrastructure elements. In the last five decades, researchers and engineers have focused on new and advanced materials to either prolong the life of existing infrastructure by means of repair and retrofitting or design and build new structures using these advanced materials. As a good example, fiber-reinforced polymers (FRPs) became an alternative material for a broad range of civil engineering applications. Also, high-strength stainless steel (HSSS) strands were introduced to the construction industry as another corrosion-resistant and potentially viable alternative to conventional carbon steel (CS) strands in corrosive environments. Accordingly, this presentation provides an overview of new developments in the use of these materials associated with derived new techniques and design methodologies, as well as the state-of-the-art and state-of-practice in advanced materials and their use in civil engineering, which promises a more durable and resilient infrastructure.

Presentation Title: Artificial Intelligence, Machine Learning, And ACI Code 562: The Future of Concrete Technology, Evaluation, And Repair

The construction sector is a dominant consumer of global resources and energy, with cement production alone contributing approximately 7% of total CO₂ emissions. This significant environmental impact underscores the imperative for sustainable methodologies, stringent quality assurance, and extended durability within the built environment. Although advancements in concrete technology offer potential solutions, the increasing complexity of cementitious compositions introduces challenges in consistently achieving desired material properties. Machine Learning (ML) emerges as a pivotal tool for optimizing mixture design parameters and forecasting material performance; however, integrating ML with established industry standards remains a focal area for development.

This presentation delves into integrating Artificial Intelligence (AI) and ML within concrete technology, structural engineering, and maintenance protocols, emphasizing advancing the implementation of the American Concrete Institute (ACI) Code 562. ACI 562 provides a structured framework for assessing, repairing, and rehabilitating concrete structures, yielding extensive inspection and diagnostic data. We explore methods by which this data can be leveraged in ML models to enhance predictive maintenance, automate deterioration detection, and refine repair decision-making processes. AI-driven models, trained on ACI 562-specific assessment data, enable continuous structural monitoring, reduce subjective assessments, and support proactive strategies for managing aging infrastructure. Moreover, the emerging AI technologies that drive compliance with ACI 562 will be examined by enabling automated data interpretation and predictive life-cycle analytics. We also investigate how ML algorithms facilitate efficient inspections by correlating sensor data with repair outcomes, thus advancing safety, sustainability, and resilience in building maintenance.Finally, in-depth technical insights into the integration of AI, ML, and ACI 562 will be delivered, highlighting the transformative potential of these technologies in structural evaluation, repair, and rehabilitation. It will give a roadmap for applying data-driven strategies to promote sustainable practices, ensure regulatory adherence, and enhance operational efficacy across the concrete and construction industries.

Presentation Title: Sustainability Aspect of Repairing and Strengthening Concrete and Masonry Structures

The preservation and repair of concrete structures are crucial for sustainability, offering significant environmental benefits over replacement. The extensive use of concrete in new construction results in substantial CO2 emissions, with the production of one metric ton of concrete releasing approximately 900 kg of CO2. Repairing concrete structures instead of replacing them can lead to considerable CO2 savings. On average, repairing a structure can save 50 to 70% of the CO2 emissions compared to a full replacement. Repairing existing structures not only reduces CO2 emissions but also conserves resources, minimizes waste, and is often more cost-effective. Considering this, the impact of prioritizing repairs over replacements becomes even more significant. Acknowledging the impact of these acts on sustainability requires an understanding of the essential methods, standards, and tools for repair of existing structures. The purpose of this presentation is to educate building owners, design professionals, and contractors on the benefits of sustainable maintenance, repair, and adaptive use of concrete and masonry structures.

Presentation Title: The Carbon Cost of Complexity: A Case for Structural Simplicity

Concrete is the most widely used construction material in the world; the sheer volume used makes it one of the single largest contributors to global CO2 emissions. However, despite its high carbon footprint, concrete also has remarkable utility, enabling the construction of adaptable and durable structures that fulfill essential human needs for shelter and infrastructure in all corners of the planet. If used judiciously, concrete has the potential to drive sustainable development at a global scale, yet we should strive to use as little as possible to achieve functional and efficient structures.

This presentation will draw on Ruggiero’s professional and research experience to critically evaluate contemporary trends in structural design, particularly in building construction. It highlights the carbon implications of structural complexity, such as irregular geometries, cantilevering volumes, and open-span spaces, which cater to aesthetic or functional demands but at an environmental cost. By exploring the link between structural complexity and embodied carbon, this talk challenges whether the trend towards more complicated structural systems is justifiable in the context of a climate crisis, and emphasizes the importance of early collaboration between engineers and architects to align aesthetic ambitions with sustainability imperatives.
