de Azambuja, Carolina M. (author), Silva, Eugênia F. (author), Capuzzo, Valdirene M.S. (author)The High Strength Concretes (HSC) provided significant advances in civil construction, due its superior strength, efficiency and durability. Due to the high content of cement, low water/cement ratio and mineral additions, it is essential to avoid the emergence of tensile stresses generated autogenous shrinkage and consequently the cracking of...conference paper 2021

Georget, Fabien (author), Wilson, William (author), Soja, Wioletta (author), Zheng, Junjie (author), Scrivener, Karen (author)Quantitative predictions for durability issues are necessary to adapt the formulations of cement blends with novel supplementary cementitious materials. These predictions are usually carried out with reactive transport models which are solved at the macroscopic scale. Upscaling laws are necessary to ensure that effective transport properties...conference paper 2021

Krstic, Marija (author), Davalos, Julio F. (author), Rossi, E. (author), Chaves Figueiredo, S. (author), Copuroglu, Oguzhan (author)Over the last few years, the United States has experienced a shortage of fly ash and slag that consequently created a need for an alternative material that is locally available, sustainable, and provides desirable concrete properties. Recent studies have shown that Ground Glass Pozzolan (GGP) offers favorable attributes as a supplementary...conference paper 2021

Kamat, Ameya (author), Abbas, Yawar (author), Blagojevic, Andrija (author), van Casteren, Toine (author), Walraven, J.C. (author)Service life of concrete infrastructure is severely compromised because of chloride-induced corrosion and measuring the chloride content is crucial to determine the remaining service life. DuraCrete provides a chloride ingress model based on Fick’s 2nd law. Although the diffusion coefficient is modelled as a time-dependent variable, the...conference paper 2021

Kleinhans, R.J. (author), Van Meerkerk, Ingmar (author), Warsen, Rianne (author), Clare, Stephen (author)Despite increasing attention on how community enterprises support community well-being and public services, we know little about how durable they are to sustain their activities. Previous research has studied individual conditions for durability, ignoring the intricate interplay between these conditions. Based on literature on community...journal article 2021
