The book gathers the peer-reviewed contributions presented at the
3rd International Conference on Application of Superabsorbent
Polymers (SAP) and Other New Admixtures towards Smart Concrete,
held in Skukuza, South Africa, on November 25-27, 2019. It features
papers focusing on the behavior of SAP in concrete (in particular
the absorption behavior) as well as the effect of SAP on fresh and
hardened concrete properties. It also covers topics such as other
modern admixtures, in particular rheology-modifying admixtures,
including the recently emerging field of bio- or waste-derived
admixtures. The conference builds on the experience and summarizes
the activities of the RILEM Technical Committee 260-RSC
"Recommendations for Use of Superabsorbent Polymers in Concrete
Construction" and addresses other prominent research activities in
the field of concrete admixtures.
This book gathers the peer-reviewed contributions presented at two
parallel, closely interconnected events on advanced construction
materials and processes, namely the 2nd International RILEM
Conference on Rheology and Processing of Construction Materials
(RheoCon2) and the 9th International RILEM Symposium on
Self-Compacting Concrete (SCC9), held in Dresden, Germany on 8-11
September 2019. The papers discuss various aspects of research on
the development, testing, and applications of cement-based and
other building materials together with their specific rheological
properties. Furthermore, the papers cover the latest findings in
the fast-growing field of self-compacting concrete, addressing
topics including components' properties and characterization;
chemical admixtures, effect of binders (incl. geopolymers, calcined
clay, etc.) and mixture design; laboratory and in-situ rheological
testing; constitutive models and flow modelling; numerical
simulations; mixing, processing and casting processes; and additive
manufacturing / 3D-printing. Also presenting case studies, the book
is of interest to researchers, graduate students, and industry
specialists, such as material suppliers, consultants and
construction experts.

This is the proceedings of the 4th International Conference on
Strain-Hardening Cement-Based Composites (SHCC4), that was held at
the Technische Universitat Dresden, Germany from 18 to 20 September
2017. The conference focused on advanced fiber-reinforced concrete
materials such as strain-hardening cement-based composites (SHCC),
textile-reinforced concrete (TRC) and high-performance
fiber-reinforced cement-based composites (HPFRCC). All these new
materials exhibit pseudo-ductile behavior resulting from the
formation of multiple, fine cracks when subject to tensile loading.
The use of such types of fiber-reinforced concrete could
revolutionize the planning, development, dimensioning, structural
and architectural design, construction of new and strengthening and
repair of existing buildings and structures in many areas of
application. The SHCC4 Conference was the follow-up of three
previous successful international events in Stellenbosch, South
Africa in 2009, Rio de Janeiro, Brazil in 2011, and Dordrecht, The
Netherlands in 2014.
This is the state-of-the-art report prepared by the RILEM TC
"Application of Super Absorbent Polymers (SAP) in concrete
construction". It gives a comprehensive overview of the properties
of SAP, specific water absorption and desorption behaviour of SAP
in fresh and hardening concrete, effects of the SAP addition on
rheological properties of fresh concrete, changes of cement paste
microstructure and mechanical properties of concrete. Furthermore,
the key advantages of using SAP are described in detail: the
ability of this material to act as an internal curing agent to
mitigate autogenous shrinkage of high-performance concrete, the
possibility to use SAP as an alternative to air-entrainment agents
in order to increase the frost resistance of concrete, and finally,
the benefit of steering the rheology of fresh cement-based
materials. The final chapter describes the first existing and
numerous prospective applications for this new concrete additive.
