Durability-enhanced cementitious composites: Superabsorbent Polymer as an effective shrinkage reducer

Durability of cementitious materials is highly dependent on shrinkage processes and a material’ susceptibility to crack formation. Typical mitigating solutions, such as addition of polymeric fibres (PF), are not always sufficient, particularly in blended cements.

The experimental data confirmed high efficiency of Superabsorbent Polymers (SAP) as shrinkage reducers in PC-GGBS fibre reinforced mortars (FRM). Significant “additional” reduction in plastic, autogenous and drying shrinkage (compared to a conventional FRM) was successfully achieved. However, the level of efficiency depends on either particle sizes and/or water absorption capacity of polymer.

SAPs facilitate hydration of Supplementary Cementitious Materials by a prolonged supply of water, adhered to smaller pores and by provision of space for deposition of secondary hydration products. This results in creation of a denser and poorly interconnected microstructure and hence in more durable cementitious composites.

Innovative binders, circularity and recyclability – how the precast industry can align with the GLOBE Consensus

With regard to climate change, the construction industry is both, responsible for existing challenges as well as inevitable part of future solutions in equal measure. The pressure to develop climate-friendly, and sustainable but likewise safe and robust construction technologies without compromising the quality of life of future generations demands for consolidated, global actions. The GLOBE Global Consensus on Sustainability in the Built Environment, for the first time calls for paradigm shift and immediate actions supported by important global networks and institutions within the built environment. The article reports about the driving force and the major objectives of GLOBE and elaborates on possible ways, how in particular also the pre-cast industry can find feasible ways towards resource saving and climate friendly technologies and production.

Wolfram Schmidt works at in the department “Safety of Structures” at BAM, responsible for the rheology and admixtures laboratory with a research focus on innovative cement and concrete constituents. Furthermore, he is secretary of the German Rheological Society, and initiator of a variety of sustainability related collaboration projects with partners from the African continent. He received the German-African Innovation Incentive Award and is member of RILEM and fib and among others convenor for sub-Saharan Africa and officer in the RILEM Development Advisory Committee.

Integration of 3D concrete printing into the modular building process

Additive manufacturing or 3D printing, already implemented in all industries is now also more and more used in the construction either on the field or in precast. Chemistry, process but also civil engineering, architecture have to be combined to able a successful and rapid implementation of environmental 3D construction printing. The initial challenges to print high quality and continuously at construction scales have been reached given us now the opportunity to spread the new technology for more efficient construction processes. The construction industry is changing rapidly with the increasing use of precast elements which allow safer, quicker and cheaper high-quality constructions. With the integration of 3D printing into the modular building process, we can further decrease the total cost with less material that can do more. The environmental considerations involve the need to reduce the quantity of construction materials but also to increase their durability. This presentation demonstrates the use of 3D printing technology for the optimization of the construction.

More prestressed components with a mobile prestressing bed

The advantages of prestressed precast elements are well known. How- ever, not every precast plant has the necessary equipment. The concept for a mobile prestressing bed can help in this situation. The production table and the lateral ribs themselves are made of precast elements that can be set up and dismantled independently of the location. In con- junction with the two cross yokes, the individual prestressing strands can be arranged in any position on the table. Each strand is prestressed individually with a prestressing jack.

Dipl.-Eng. Thomas Friedrich, Innogration GmbH, Bernkastel- Kues, Germany studied civil engineering at RWTH Aachen University and at ETH Zurich with a scholarship from The German National Academic Foundation. His activities have included: project engineer at Stahlton/BBR, a prestressing company in Zurich; managing director of Domostatik, an engineering company he founded in 1988. From 2003 onwards, he has been engaged in developing a new type of prefabricated floor system with integrated technical building services. Proprietor of numerous patents for newly developed products in the construction sector, he founded Innogration GmbH in 2010 for the advanced development and marketing of this new multi-functional floor system; he is managing partner of Innogration GmbH. He has been lecturer at the special department of solid construction at Kaiserslautern University of Technology since 2008.

With BIM and digitalization towards the robotization of construction

Europe has its own plan to stimulate economic recovery from the pandemic crisis. The new Europe is supposed to be greener, more resilient to crises and also more digital. So, what should the future of concrete construction and engineering look like? With huge investments expected, we are witnessing rising prices of cement, aggregates, steel, accompanied by shortages and transportation problems. The number and role of digital solutions in the design, construction and maintenance processes is growing. That's why we need BIM and digital technologies even more today. Without them, we won’t be able to increase the still too low degree of automation and robotization. And this is all a new challenge for concrete engineering.

Prof. at the Silesian University of Technology. Bridge engineer, an expert in CAD, BIM and digital construction. He promoted five doctors in bridge dynamics, prestressed concrete, SHM, BIM and AI in bridge optimization and diagnostics. Current interests include BIM, Asset Management and Mixed Reality in bridge management and inspection. Creator of an accredited research laboratory for testing bridges.

Concrete recycling – differentiation by material type and particle size

As the dominant building material of the present, concrete must also be given priority when it comes to the circular economy. On the way to- wards increased circular economy, a wealth of research results has been developed, much of which is hardly used in current practice. In contrast to natural aggregates, recycled concrete aggregates are composites of aggregates and hardened cement paste. The ratio of these two compo- nents depends on the respective “parent concrete” and the particle size, and determines the properties of the recycled aggregate. If applied for manufacture of new concrete elements and structures, the total ce- ment paste content in the concrete increases. This results in systematic changes in mechanical properties and a higher deviation in material properties. In the national regulations, recycled aggregates that are to be used for concrete production must meet certain requirements for material composition.

Ducon Overlay - High-performance concrete for strength and endurance

The patented Ducon technology offers various application possibilities in the field of renovation, re-pair, and reinforcement of horizontal to vertical surfaces. Ducon impresses with a high load-bearing capacity and abrasion resistance from a layer thickness of just 30 to 40 mm. A version in accordance with the Federal Water Act (for facilities handling substances that are hazardous to water) is available from 55 mm (Ducon55). Construction measures for renovation can be executed with minimal disrup-tion to ongoing operations. The low layer thickness makes it unnecessary to demolish the existing surfaces. This results in enormous savings in downtime. The preparation of the substrate is also shortened, as the material properties of Ducon make separate treat- ment of existing joints and cracks in the substrate unnecessary.

Dr.-Ing. Stephan Hauser is Managing Director of DUCON GmbH und DUCON Europe mbH&Co.KG, Moerfelden-Walldorf. He completed his studies of Civil Engineering at the University of Technology Darmstadt. From 1992 – 1995 he was employed by Philipp Holzmann AG as Project Manager in the department of structural engineering. He subsequently obtained his PhD at TU Darmstadt, on the topic of micro-rein- forced, ultra-high-performance concrete DUCON. From 1999-2004 Dr. Hauser worked for Hochtief AG as the Head of site-management and Project Manager of large construction sites. In 2004, he established the DUCON GmbH after the international DUCON-patent had been granted.

Sensor-based method for testing the segregation stability of modern concretes

The presentation introduces a quick test for the segregation stability of concrete with flowable to self-compacting concistencies. Up to now, the evaluation has been carried out with a time-consuming and unfortu- nately also time-delayed washout test. The new approach uses a probe with three moisture sensors that provide measurements at different heights, either after vibration (in the case of vibrated concrete) or, in the case of self-compacting concrete, after the onset of stiffening of the concrete. Especially in the case of vibrated concrete, reliable results as to whether the concrete is stable or not can be obtained very quickly. With the vibrating table, the compaction methods and intensities that occur in practice can be reproduced. The end result is an easy-to-use device that helps the user on site to decide whether the concrete or the vibration duration or intensity is suitable.

Paving stones from 100% recycled raw materials

In a project between the University of Kassel and the company F.C. Nüdling, a paving stone based on recycled aggregates and CO2-reduced binders has been developed, optimized and tested for durability. For the CO2-reduced binders, two different options were tested. For one formulation a CEM III A was used and another one with alkali-activated material based on slag activated with sodium hydroxide. The objective of using recycled aggregates only could be met and good results regarding strength could be achieved in laboratory tests and in tests on site of a concrete plant. The durability tests did not yet show the required results for the paving stone of both the laboratory tests as well as those produced on site in the concrete plant. Two-layered pavers generally show higher durability, which could be confirmed in the laboratory tests for the adapted formulations but have not yet been tested for industrial trials. The reduced durability of one-layered paving stones is mainly due to the recycled aggregate, which has a relatively high porosity compared to the natural aggregate. In general, it was clearly demonstrated in this project with the aid of a life cycle assessment that an improvement in the CO2, material, water and energy footprint can be achieved both through the use of recycled aggregates and through the use of alkali-activated binders instead of Ordinary Portland Cement.

Dr. Alexander Wetzel studied geosciences at the Georg August University of Göttingen with a focus on applied mineralogy. He received his doctorate at the Institute of Geology of the University of Bern. Since 2011 he has been a lecturer at the Department of Building Materials and Construction Chemistry of the University of Kassel.
