Considering current situation of COVID-19 in the Netherlands and in European, it will be very difficult to organize a physical conference in the end of this April in the Hague. Furthermore we have already postponed the conference two times so that the conference organizing committee has decided to change the Microdurability conference to an online conference.

Learnt from other successful online events, it would be very hard for participants to sit the whole day in front of screen in three consecutive days. Thus we plan to organize the Microdurability conference as a series of webinars throughout the month of April and May. In each series, we will plan three parallel sessions within 2 hours. Each parallel session may contribute to a specific topic. There are 7 presentations in each session. Every presentation lasts 15 min (12 min pre-recorded video + 3 min live Q&A). A deep discussion is expected in the end of each session. Preliminary schedule of the conference is listed in Table 1.

International RILEM Conference on Microstructure Related Durability of Cementitious Composites (Microdurability)  is a Sino-Dutch initiative, organized under the umbrella of RILEM and also supported by ACI, fib. After three successful events in Nanjing 2008, Amsterdam 2012 and Nanjing 2016, the fourth Microdurability conference will be held ONLINE.

In the recent years, alternative binders, supplementary cementitious materials and different industrial or regional wastes were used in concrete in order to improve concrete properties, and to reduce the carbon footprint of the construction industry. The consequence of these actions will change the chemistry, microstructure, and further influence the durability of concrete. Based on this concept the aim of the 4th Microdurablity conference is to bring together the leading experts in this field from around the world to present the recent achievements, share the latest developments and address the challenges on the microstructure related durability issues of cementitious materials.

Main Topics

  • Alternative binders, supplementary cementitious materials and industrial or regional wastes used in concrete
  • Hydration and microstructure formation
  • Transport properties in cracked and uncracked concrete
  • Chemical and physical degradation under coupled loading conditions.
  • Effect of time dependent phenomena and ageing on microstructure and durability
  • New techniques for evaluation of hydration, microstructure and service life
  • Development and application of smart cementitious materials for enhanced durability
  • Modeling of microstructure, transport, degradation processes and design for durability.
