Proceedings pro095 : International RILEM Conference on Application of Superabsorbent Polymers and Other New Admixtures in Concrete Construction
Title: International RILEM Conference on Application of Superabsorbent Polymers and Other New Admixtures in Concrete Construction Edited by Viktor Mechtcherine and Christof Schroefl ISBN: 978-2-35158-147-6 e-ISBN: 978-2-35158-148-3 Publisher: RILEM Publications SARL Pages: 394 Publication date: 2014 |
Superabsorbent polymers (SAPs) are a remarkable example of multipurpose additive in cement-based materials. SAPs enable the discrete control of water availability and porosity formation, they can be used in modifying rheology, mitigating plastic shrinkage and self-desiccation, protecting concrete from frost damage, supporting the self-healing of concrete, and assisting in several other ways. The goal of the conference has been to provide a thourogh overview of the research and developments on use of SAPs and their working mechanisms in cement-based systems. Other admixtures covered at the conference include, among others, internal curing agents, shrinkage reducers, stabilisers, and agents to control the pore system. Contributions deal with insights gained from experimental studies, theory, or modelling. A wide range of concrete properties affected by the new admixtures are treated: rheology, shrinkage and shrinkage induced cracking, mechanical properties, durability, etc. Special focus is directed at chemical and other approaches in characterising the working mechanisms of the admixtures and improving their performance.
The scientific sponsor of the conference is Technical Committee 225-SAP “Application of superabsorbent polymers in concrete construction”, initiated within RILEM in 2007. The activities of this Technical Committee are about to come to an end in the form of this conference. A state-of-the-art report has been compiled and published in 2012 by Springer.
