Improved construction techniques The second project aims to fulfill COIN's vision of attractive concrete buildings and structures by focusing on the design and beautification of surfaces, industrialized production, effective processes, reduced costs, and reduced load on the workers and the environment.\n The specific goals of this project include: * Laboratory and field studies of new and existing methods for obtaining critical chloride content; * Establishment of a database for relevant input parameters to be used in a service-life model based on Fick's second law of diffusion; * Establishment of important and missing relationships between resistivity and service life as it relates to corrosion of reinforcement, and thereby develop service life models that include resistivity. Such knowledge is essential for a future performance test concept that enables flexible solutions for the stakeholders; * Studies of different preventive measures, such as surface protection, low-corrosion steel reinforcement, and corrosion inhibitors, on the service life of concrete structures exposed to corrosion-inducing substances; and * Modeling and prediction of residual service life and load-bearing capacity of concrete structures with ongoing reinforcement corrosion for different limit states including cracking, spalling, and collapse Energy efficiency and comfort This project's main goal is to develop knowledge about how to design buildings with activation of thermal mass for maximum energy savings, good indoor climate, and good architectural design.
COIN: Concrete Innovation Center one of norway’s centers for research-based Innovation focuses on the concrete industry by Tor Arne HAmmer T he Concrete Innovation Center (COIN) is one of 14 Centers for Research-Based Innovation (CRI)—an initiative by the Research Council of Norway. The main quality, productivity, and working environments, there will inevitably be an increasing trend toward tailoring of properties, a higher degree of indoor prefabrication, and objective of the CRIs is to enhance the innovation increased emphasis on premixed products. capability of the business sector by focusing on long-term Sustainable development will still be emphasized by research through close alliances between research- politicians in the coming years. The sustainability of intensive enterprises and prominent research groups. buildings and structures is strongly influenced by the The vision of COIN is the creation of more attractive choices made in design and construction, and it should concrete buildings and structures—not only in terms of be evaluated for the whole service life of the building. aesthetics but also in terms of functionality, sustainability, Recent studies reveal the possibility for significant energy efficiency, indoor climate, industrialized construction, reductions in energy consumption in buildings—up to improved work environment, and cost efficiency over the 15% for heating and 50% for cooling—by taking advantage entire service life. To fulfill this vision, COIN hopes to of the high thermal mass of concrete.1 The concrete develop a major leap forward in advanced materials, industry also faces challenges related to environmental efficient construction techniques, and new design impact, depletion of resources, and energy consumption. concepts combined with more environmentally friendly The use of concrete involves consumption of vast material production. amounts of raw materials. Thus, the industry is facing rapidly increasing challenges related to global BACKGROUND AND RESEARCH SIGNIFICANCE environmental requirements and resource availability A major challenge facing the concrete industry is the that force the concrete industry to look for alternative paradox that concrete is an essential necessity but has a solutions. By reducing emissions, energy consumption, low public image. Hence, it’s important for the industry to and the impact on natural resources, these solutions create a more realistic and positive image of its products. should improve sustainability while maintaining It’s likewise important to make concrete buildings more market share. attractive to gain a stronger position among building Aggregates that were once quarried from natural owners, architects, contractors, and the public thereby resources are now increasingly produced from crushed rock increasing market share, especially in housing. To do and secondary raw materials, such as demolition waste, this, there is a need to improve the quality of concrete because the natural resources are depleted or rejected for products and make them even more cost efficient and environmenta
