DuRSAAM - Durable, Reliable and Sustainable Structures with Alkali-Activated Materials

Goal: The design, durability and performance of structures play a crucial role in fostering societal and economic growth. Concrete structures are used extensively for buildings, transport, infrastructure and maritime applications. By using concrete extraordinary structures can be realised, and these are often designed for long service lives to gain optimal value from the material, environmental, intellectual and financial input into the making of the structure. In Europe, around 4 tonnes of concrete per capita are consumed annually. The downside of using concrete is associated with durability issues and huge environmental costs, as the cement industry accounts for 8% of global anthropogenic carbon dioxide emissions; and around 60% of all non-renewable resources are used in construction, making it one of the least sustainable industries. There is a clear demand for a new, sustainable generation of construction materials, since Ordinary Portland Cement (OPC)-based concrete cannot meet all the challenges of modern society concerning durability and sustainability. The DuRSAAM action addresses this by establishing a training and research network contributing to a sustainable built environment using AAM concrete.

Alkali Activated Materials (AAMs), which are locally available alumino-silicate based materials , are emerging as alternative binders to Ordinary Portland Cement (OPC) due to higher performance and reduced carbon footprint. Before their implementation on a larger scale, their durability performance needs to be fully understood. The data on durability performance of AAMs under single environmental action are limited, and there are almost no data on their behaviour under two or more environmental actions. This article provides brief literature review on novel methods for determining durability of concrete under combined environmental actions, which could be utilised to determine the behaviour of AAMs under combined environmental actions. Ponašanje betona pri kombiniranom djelovanju okoliša i mogućnosti primjene na alkalno-aktivirane materijale Sažetak Alkalno aktivirani materijali (AAM), koji su lokalno dostupni materijali na bazi alumino-silikata, postaju alternativa običnom portlandskom cementu (OPC) zbog poboljšanih svojstava i sma-njenog ugljičnog otiska. Prije značajnije upotrebe u praksi, potrebno je u potpunosti razumjeti njihovo ponašanje u različitim okolišima. Postoje ograničeni podaci o dugotrajnom ponašanju AAM-a pod jednim djelovanjem iz okoliša i gotovo da nema podataka o njihovom ponašanju pri kombiniranom djelovanju dva ili više opterećenja iz okoliša. Ovaj rad daje kratki pregled literature o metodama za određivanje trajnosti betona pri kombiniranom djelovanju različitih opterećenja iz okoliša te osvrt na mogućnosti primjene za analizu otpornosti AAM-a. Ključne riječi: trajnost, alkalno-aktivirani materijali, degradacijski mehanizmi, kombinirani utjecaj okoliša SIMPOZIJ DOKTORSKOG STUDIJA GRAĐEVINARSTVA 2020

Alkali-activated materials are a group of alternative binders based on aluminosilicate precursor and an alkali activator. Since precursors are mostly waste materials and by-products, AAMs are consideredto be a valid and more environmental-friendly alternative to Portland cement. Although the AAMs show good performance, there are not enough studies in the literature about their long-term durability performance related to chloride ingress and embedded steel corrosion. The issue of this paper is to highlight the main difference between OPC and the different types of AAMs, and to give a short introduction about the state of art of this embedded steel corrosion.
