Minimising carbon dioxide emissions of concretes using nonlinear modelling

There has been a surge in interest in reducing carbon dioxide emissions from concretes. Cement suppliers produce CEM II grades with varying amounts of slags. The optimal amount of slag will depend on various constraints and requirements of the concrete plant. It is important to determine recipes that serve the purpose well, instead of just using cements containing slags. Experiments were carried out to mathematically determine optimal recipes for minimal cost and for minimal carbon dioxide emissions. Nonlinear models were developed for early strength, 28 day strength and workability.

An Ice-Based Robotic Manufacturing Method for Precast Concrete Industry

Contemporary architectural and structural design often requires fabrication of complex and non-serial concrete elements. Existing digital methods of manufacturing formwork of a complex geometry, such as CNC milled EPS foam molds, usually produce large amount of waste that is difficult to manage in a sustainable way. The idea of using ice as the formwork material seeks to resolve the problem of waste, as well as to reduce manual labor requited for preparation and demolding cast concrete. The concept of ice formwork has proved its validity through laboratory testing, providing very positive results of sub-freezing cement hydration and the total concrete strength gain, as well as excellent surface finish of in-ice cast concrete.

Derivation and evaluation of conformity criteria for concrete

Conformity control is an important step in the quality control of manufactured products. This also holds for concrete where an additional problem arises by the fact that the main mechanical characteristics can only be determined at a certain age (e.g. 28 days). In the presentation common types of conformity criteria for concrete will be described (control by attributes and control by variables), the derivation of operating characteristics corresponding to conformity criteria will be explained and it will be elaborated how the conformity criteria can be designed. Furthermore, current conformity criteria (such as those in EN206-1) will be assessed. Finally, also the theoretical basis and implementation of a conformity control scheme on the basis of control charts (as recently incorporated in EN206-1) will be explained and evaluated.

Modular and fully automated production process for free-form concrete moulds on the basis of technical waxes

The goal of this research cooperation between B+S Engineering GmbH from Rheine, Germany and the Institute of Structural Design (ITE) at the TU Braunschweig, Germany, funded by AiF Projekt GmbH (project-executing organization of the Federal Ministry of Industry and Energy (BMWi) for "ZIM cooperation projects" - funding period mid-2017 to end 2018), is to examine the economic efficiency and ecological sustainability of wax moulds for free-form concrete structural elements and to develop the non-waste wax mould technology [6] into an application suitable for construction practice. The manufacture of free-formed concrete structural elements in a cost-effective and resource-saving industrial process is to be made possible through the development of a fully automated production process. By adding together modular wax mould segments to form a complete mould, concrete structural elements can be manufactured with an almost unlimited range of shapes and in a size that is almost arbitrarily extendable. Serial unique items can be manufactured cost-effectively through the merging of individualized manufacturing technology and serial process technology.

Quality control in concrete product manufacturing facilities

Quality and price are the most important customer criteria when it comes to the purchase of concrete products. Therefore, it must be the objective of every producer to offer products in a quality that is second to none and at a cost that is as low as possible. These goals can only be accomplished if there are suitable structures and processes available for the important task of quality control in a production facility. For this purpose, it is mandatory, apart from developing the necessary organization, to detect and discuss the possible causes of quality deficiencies

Design Thinking - A contemporary method of creating paving products

The dynamic development of spatial and urban planning, as well as increased requirements in the paving product segment in the public and private investment sector forces the producers of concrete materials to prepare new and more creative product offers. Conscious clients expect aesthetic and functional products, but above all products that meet all technical requirements. The modern method for developing innovative products – Design Thinking – allows to provide customers with exactly this kind of solutions. This innovative approach to the creation and implementation of products has been invented at Stanford University in California. The first promoter of the design thinking idea was David M. Kally, the author of IDEO - a leading organization of innovative products. Design Thinking has become a commercially applied tool and the rapid expansion of new thinking into the areas of global business pushed David Kally to set up the Institute of Design at Stanford University. This interdisciplinary design center implements tasks and strategies for many industries and institutions worldwide. A promoter of this method in Europe is the HPI School of Design Thinking in Potsdam.

BIM in construction in the context of industrial revolution 4.0

The European Directive 014/24/EU on public procurement was announced in 2014. Its implementation may drastically change the entire European market in the scope of public investment. This refers i.a. to the application of electronic devices for construction data simulation. These devices are BIM - Building Information Modelling - technologies, more and more often used in designing. According to the legislators’ intention, the application of BIM may contribute to the optimization of designing and completing public construction investments through the integration of design and construction process and facilitation of building management. Some western countries have already introduced the obligation to apply BIM and other are getting ready for it. In the last months BIM has undoubtedly been one of the most frequently used abbreviations in construction industry, not only in Poland.

Influence of quality control on the safety level of concrete elements

Quality inspection plays an important role in the production process of concrete, as it inherently stimulates producers for obtaining a higher performance with respect to the investigated properties. In case of the conformity assessment of concrete compressive strength, the concrete strength distribution is filtered due to the rejection or acceptance of certain batches and this filter effect can be quantified using Bayesian updating techniques. As a consequence of the filter effect, conformity control has a positive influence on the structural reliability of concrete structures. This filter effect can be quantified as well using structural reliability calculations. In order to illustrate the influence of conformity control on structural reliability, concrete elements (columns and beams) which are designed according to the Eurocodes, are analysed considering basic limit state equations, i.e. for compression and bending. The results are discussed and some general observations are made.

Yield - an undervalued QC instrument for concrete production

Quality of concrete is usually assessed by compressive strength: concrete classes, specifications, requirements and compliances are all based on 28-day compressive strength. The quality assurance systems assume that if concrete constituents, their quality and their quantities do not change, the 28-day strength should be consistent within acceptable variation expressed in standard deviation. This is true, when exact quantity and quality are known, and reliably measured. However, when they are not, then changes in concrete quality may go undetected until some strength results become available. But this may take 7 or even 28 days until it is realised that quality of concrete was jeopardised. The concrete yield test can be of a great assistance to quickly realise some of the issues with produces concrete while other commonly used fresh concrete tests and indicators fail to identify.

Advantages of a dual mixing system

The acceleration of the hardening of precast concrete elements is one of the topical problems to be solved. New methods are proposed that help to increase the early concrete strength and to reduce the time needed for strip-ping. Focus of last research is to implement fundamentally new equipment in concrete precast industry and the improvement of technology.

One of the effective ways to improve the quality of concretes is to use high-speed turbulent mixers for the sepa-rate production of slurry in a two-step mixing process. Two step mixing processes have not found wide application in the production of standard and self-compacting concrete up to date, mainly due to the lack of highly effective superplasticizers and low water-cement ratios. The questions of handling a two-step mixing process sin industrial scale remains open, as well as the choice of the optimal time for achieving the maximum technological effect.

Development of a new steel fiber for application in concrete

The fields of application for steel fibre reinforcement are very diverse. Steel fibres can be utilised in combination with conventional reinforcement or else replace it entirely. This means that using steel fibres can lead to a reduction in cost for reinforcing work and, thus in turn, for an overall project. It requires correspondingly great post-cracking tensile strength from the steel fibre reinforced concrete as well as homogenous fibre distribution in the construction component. A new type of steel fibre made by Feel Fiber Gmbh meets these requirements in an efficient manner. The fibre possesses a straight shape and anchor knots at its ends. The number, position and size of these anchor knots can be specified very flexibly thanks to an innovative manufacturing method, through which load-bearing behaviour can be optimised according to project conditions. It may be assumed that their straight shape without hooks at the end will exert a minor influence on fresh concrete properties, exhibit low propensity to balling and, as a consequence, homogeneous fibre distribution. These assumptions were able to be confirmed in extensive experimental investigations.
