Technical Seminar/ Webinar on Balancing Sustainability and Durability in Slag-Rich Concretes: Pathways to Low-Carbon Construction (Jointly organized by HKIE BUD & HKICM)

22 December 2025

Concrete production remains one of the largest contributors to global CO₂ emissions, primarily due to the high clinker content in Portland cement. The incorporation of industrial by-products such as ground granulated blast-furnace slag (GGBS) offers a practical pathway to reducing the carbon footprint of concrete. However, achieving a balance between sustainability and long-term durability remains a central challenge for the construction industry. This presentation explores the role of slag-rich concrete systems in decarbonizing construction while maintaining mechanical performance and durability. Drawing from recent international research, it discusses key aspects of mix design optimization, life-cycle assessment (LCA) of slag-based concretes, and the influence of microstructure on durability-related phenomena such as carbonation and chloride ingress. Emphasis is placed on the synergy between material sustainability and service life, highlighting how microstructural control and supplementary additives can enhance performance in low-clinker systems. The session aims to provide a concise overview suitable for both researchers and practitioners, outlining how the integration of circular materials, performance-based design, and microstructural understanding can drive the next generation of sustainable, durable concretes.

Speaker(s):

Georgina Mihailovschi (Krystaline Technology SL, Spain)

 

She is a Civil Engineer (University of Buenos Aires – Argentina) with more than 15 years of specialized experience in concrete technology, construction materials, and quality management systems applied to civil engineering. She currently serves as Head of the Concrete Division at Krystaline, where she leads the development and quality control of advanced solutions aimed at improving the durability, sustainability, and efficiency of concrete for application in infrastructure projects. In this role, she integrates applied research, material innovation, and the transfer of knowledge into professional practice. Her career includes the management of laboratories and the implementation of Quality Management Systems (ISO 9001:2015) at the ready-mix concrete company Ingeniero José María Casas S.A., where she coordinated testing of fresh and hardened concrete, supervised the quality of raw materials and recycled aggregates, and participated in internal and external audits. In Spain, she also gained on-site experience with Ferrovial Construcciones and Grupo Aldesa, where she carried out quality control tasks and environmental monitoring on large scale infrastructure projects, including both civil works and building construction. In academia and research, she worked as a university lecturer at the University of Buenos Aires and at the Army Technical College (Escuela Superior Técnica del Ejército Argentino), teaching courses related to materials and concrete technology. She also worked in the National Institute of Industrial Technology (INTI) – Concrete Technology Unit, where she developed research projects, conducted technical audits, advised companies on production processes, and participated in the drafting of standards within the IRAM Concrete Subcommittee. Her international training was strengthened through an Erasmus Scholarship at the École Nationale de Ponts et Chaussées (France) and academic stays in structural and materials laboratories at the University of Coimbra (Portugal). Additionally, she completed a Diploma in Quality Management (IRAM) and a Postgraduate Program in Renewable Energies (UCA), which allowed her to integrate technical expertise with sustainability criteria. Her multicultural experience has enabled her to build a professional profile focused on technical excellence, innovation in concrete technology, and quality management, providing strategic value to infrastructure projects and to the development of cutting-edge materials in civil engineering.
