Keynote speakers

Ioannis A. Kartsonakis, NTUA, Greece

Smart admixtures with active functionality

Concrete can be nano-engineered by the incorporation of a variety of nano- and micro-sized structures with superior characteristics, such as superabsorbent polymers, carbon-based fillers, carbon nanofibers and nanotubes, hybrid organic-inorganic nanostructures, layered double hydroxides, nano/microcapsules, self-healing polymers. These materials contribute to the development of a new generation of tailored, multifunctional concrete and add self-responsive capabilities especially to concrete structures working under severe conditions.

Multifunctional bulk reinforced-concrete materials to operate under severe conditions

The Lorcenis project has the ambition of extending the service life of energy infrastructures exposed to some of the harshest environmental conditions, through the implementation of novel additive types not used in today's concrete practice. The performance requirements implied the development of a dozen of state-of-the-art technological concrete mix designs which had to (1) meet the most challenging specifications identified through an in-depth analysis of today's field best practice and (2) be incrementally modified to afford the implementation of Lorcenis' novel additives while maintaining their fresh and hardened properties. This keynote aims at giving an overview of the whole process chain, from the identification and definition of the effective environmental conditions and their impact on exposed concrete structures, the best-in-practice corresponding concrete mix designs and their development, the implementation of the novel durability additives and evaluation of their efficiency through accelerated durability testing according to the international norm protocols.

Experimental and numerical study of a vascular self-healing system for cementitious materials

One of the challenges of numerical research on self-healing cementitious materials is that the precise data needed to develop a model, and subsequently validate it, are often incomplete. To address this issue, a combined programme of experimental and numerical research has been undertaken at Cardiff University aimed at developing a comprehensive numerical model for a self-healing system based on vascular networks. The experiments undertaken to understand the behaviour of the system encompass the flow behaviour of healing agents in micro-cracked cementitious elements, the curing behaviour of a healing-agent in a cementitious environment, and multiple and overlapping mechanical damage/healing 'events'. The numerical model derived from these experimental observations is a coupled finite element model that simulates all of the aforementioned aspects of behaviour.

Providing engineers with a tool for the design of concrete coverage

The process leading to spalling of concrete cover of steel reinforcements involves the transport of chemical species in concrete, chemical reactions in concrete, corrosion of the rebar, and finally micro-cracking and crack coalescence around the rebar. Research models capturing this process require significant computing power, need input values that are difficult to obtain experimentally and must be operated by specialists. This effectively puts such models out of reach of engineering practice. In the LORCENIS project, one goal has been to create a tool simple enough for routine use in the design of concrete coverage.

Jose Vera Agullo, ACCIONA Construction S.A., Spain

Durability of concrete infrastructure and the role of smart self-responsiveness admixtures

ACCIONA Construction S.A., a Spanish contractor, is deeply interested in offering to its clients long service life-spans for the infrastructure delivered. There is a clear tendency in the sector of clients asking for longer life spans than ever, up to 120 years in critical structures like bridges. This tendency is pushing the civil engineering technology to search for innovative and reliable solutions. One part of this effort is focused on the material science and technology, and more specifically in the development of self-responsiveness admixtures to be used in concrete. In this work, a summary of the approach of the LORCENIS project is given, showing the demonstrators built in different harsh scenarios: North sea, mechanical fatigue, thermal fatigue and acid attack.

Safety and sustainability of new admixtures for durable concrete

The sustainability of concrete infrastructure is highly dependent on the durability. A longer service life with low repair work reduces the resource use and hence the greenhouse gas emissions. New admixtures based on nanomaterials have the possibility to increase the service life. However, it is also important to consider the embodied impact of the material and safety issues concerning new nanomaterials. Here we present an overview on the safety and sustainability of some novel admixtures.
