Proceedings pro091 : RILEM International Symposium on Concrete Modelling - CONMOD 2014

Title: RILEM International Symposium on Concrete Modelling - CONMOD 2014 Edited by Kefei Li, Peiyu Yan and Rongwei Yang ISBN: 978-2-35158-139-1 e-ISBN: 978-2-35158-140-7 Publisher: RILEM Publications SARL Pages: 511 Publication date: 2015

CONMOD 2014 is the fourth in a series of RILEM symposia after Quebec City, Canada (2006) and Delft, The Netherlands (2008) and Lausanne, Switzerland (2010). The Symposium is devoted to the development and applications of numerical models to simulate and predict the microstructure, material properties and long-term performance of concrete. CONMOD conferences provide a platform for researchers active in modeling of concrete at different length scales, and from different disciplines. This series of conference offer also an exchange platform for the PhD students conducting research on concrete materials.

Modeling is a vehicle to transfer the knowledge from scientist to engineers. The rapid development in computational capacity and techniques has promoted substantially the modeling on concrete materials. The solution of some sophisticated problems, like multi-physic processes, is only possible through computer-based methods. The models, reinforced by these advanced techniques, can greatly help the engineers to design and evaluate the behaviors of concrete materials and structures in the context of life cycle engineering.

CONMOD2014 has gathered participants from 15 countries, and collected 61 papers in the proceedings. The papers are divided into five main topics: Hydration and microstructure, Properties characterization, Transport process, Shrinkage and creep, and Durability. These papers embrace both the most recent development in modeling techniques and the new knowledge on concrete materials. The intended readers of the proceedings include graduate students and scientists on concrete research as well as engineers in concrete technology and structural design.
