Part of this project is to upgrade the MacKays to Peka Peka Expressway. The so called M2PP project is being built by an alliance made up of the NZ Transport Agency and several specialized planning and construction companies. This means an innovation in the way the project is being delivered, setting new standards for the construction industry in New Zealand. A best possible concrete consolidation and finish were set as high priority measures to fulfill.
  • Excellent German-Italian cooperation for Arabtec Precast in Saudi Arabia In October 2013 the specialists of the vibration technology manufacturer BRECON and the formwork manufacturer tecnocom teamed up in cooperation for the installation of battery moulds at Arabtec Precast L.L.C., Saudi Arabia.
  • Vibration monitoring for quality assurance Vibration is crucial to the concrete compaction process to achieve the required strength and surface quality. VibraMon is a new system for documenting this vibration process. Recording the relevant data during the compaction process enables the complete documentation of the whole process for every single precast concrete element. By filling an important gap in the process chain, monitoring the vibration process offers companies, for whom quality reproduction is a particularly difficult requirement to fulfil, the means to do so.
  • Prevention of damage due to the use of a vibrator Both normal frequency (50/60 Hz) and high frequency (100-200 Hz) vibrators are used for the compaction of concrete. The vibrator is selected primarily for its centrifugal force at a particular speed. At best, achievement of the desired concrete density or at worst, damage, depends on the correct selection and installation of the formwork or machinery. The following tips are designed to help in the correct selection of vibration technology.
  • Robust radio controller for use in concrete plants The control of processes by radio control not only pays dividends in the highly automated production of prefabricated elements, but also in case of long distance or when vibration parameters need to be varied during production, independent of where the worker is. Therefore, BRECON (and previously BOSCH) has allowed the control of vibration for concrete compaction via radio control for more than 25 years now. Based on this long term experience, BRECON has developed the next generation of radio controls that take into account the harsh conditions in concrete plants.
  • High-precision test table for vertical and horizontal vibration In the field of architecturally demanding concrete surfaces and delicate construction elements made of special materials, e.g. with an epoxy portion, extensive development projects are frequently necessary in order to determine the influence of the possible vibration parameters during the concrete compaction. High-precision test tables, with which these parameters can be accurately predicted, are used for this.
  • Two Vibrators in one The compaction of concrete in two steps accelerates the pouring of the concrete and the compaction process in certain applications. This is achieved through the specific use of different centrifugal forces and/or frequencies. For those applications typically the use of high frequency vibrators in combination with normal frequency vibrators is required. The BRECON 2in1-vibrator is capable of executing both processes with just one type of vibrator.
  • The lightest quick-release-clamp vibrator of its class Quick-release-vibrators are used wherever many moulds exist, but where each individual mould is used only rarely. The new Slim2 quickrelease-vibrator by BRECON is characterised by a reduction in weight of 25 % and outstanding handling. Quick-release-vibrators from the Slim2 series offer the possibility to change vibrators quickly and easily from one mould to the next and have long since found their place in concrete compaction.
  • Simple measurement of the frequency and amplitude of vibration The field of vibration technology is of importance in almost all industries. The two largest areas of application are to be found in conveying equipment and the concrete industry. However, not only concrete is compacted by means of vibration in order to improve its mechanical properties. Every chocolate, many cast plastics and also powdery bulk goods are compacted using vibration. If used correctly, vibration improves the flowability of both liquid and solid materials. The key parameters are thereby the amplitude and the frequency of the vibration used. The two together are decisive for the vibration energy applied to the medium.
  • The World’s most modern and extensive vibration system is put into operation. In late 2006 the form manufacturer, Weckenmann, approached the vibration specialists at BRECON with a request for a joint venture in a project that, with 9 battery forms, was in every respect, extraordinary. As part of modernization measures at the DSK Blok concrete precast factory in St. Petersburg, Russia, the intention was to install battery forms for the vertical manufacture of wall elements, in addition to, a new pallet circulating plant for the horizontal production of slabs. A total of 9 battery forms, for vertical manufacturing of wall panels each with 2 sections containing 10 chambers each for wall panels were planned in two neighbouring bays. Besides the enormous dimensions of the steelwork, high demands with regard to vibration technology had to be discussed.
  • SL-Vibration in combination with Omnivib Control Technology After the take over of an existing production facility located in Nottuln, Germany, it was clear to the companies’ management, Mall Umweltsysteme GmbH, that they needed to modernize and expand the existing production facilities. With the Synchronized-Vibration Technology (SL) in combination with the Omnivib-Control Technology from BRECON, they found a solution that fulfilled the high standards of productivity and concrete quality equal to their other locations. At the same time they could combine the existing equipment and the new technology to one system. The effect of the noise reduction was an essential advantage to the SL-technology.
  • Modern compaction technology at P.V. Prefabet in Poland P.V. Prefabet has developed a new production system with pipe moulds and vibrating tables at Krapkowice, Poland. After thoroughly testing different production technologies, it was decided to acquire the compaction system using the new synchronous running (SR) vibrators from BRECON. Production had already been expanded several times with further SR vibrators and electronic inverters from BRECON being installed.
  • Overview and comparison of vibrator technologies for formworks Since the 1950’s, the activities of BOSCH have included the development and production of vibrators for precast element formworks. And since 1995, BRECON has taken over the further development of these technologies under license from BOSCH. Much experience with the different technologies (pneumatic, electrical and electromagnetic) and applications in the low (approx. 3,600 rpm) and high (from approx. 4,500 rpm) frequency ranges has also been gained during this period. This report describes the advantages and disadvantages of the different techniques and shows which frequency range gives the best results for concrete compaction. The possibilities of conversion to the new SL technology is also discussed.
  • Vibration technology or self-compacting concrete (SCC)? Are these processes really in competition with each other? At trade fairs in particular, visitors occasionally express the opinion without prompting that the manufacturers of vibration motors will soon disappear because the technology has been displaced by SCC. Statements like these show that very many users, particularly in the precast concrete element industry, are concerned about this subject. However, what are the special strengths and weaknesses of these two processes? For which application is SCC of interest and what are its limitations?
  • Mobile vibration controls increasingly used for concrete compaction In 1995 BRECON, of Cologne, Germany, took over the worldwide sales of the BOSCH vibration technology. Since 1997 the company’s own control manufacturing unit has been producing an extensive standard range of frequency controls. Since then over 200 control systems have been delivered for permanently mounted installations - mostly for the operation of several different types of formwork. The Omnivib expandable system is already mainly aimed at customised special solutions, using PLC programming and radio remote control.
  • Innovative synchronous vibrators convincing in first practical use A newly developed synchronous running vibration system (SL vibrator) from BRECON Vibrationstechnik GmbH, from Cologne, Germany, has successfully mastered its premiere at a precast concrete element plant. The Dressler concrete plant in Stockstadt, Germany was the first user for this innovative technology for homogenous compaction using the synchronous running technique. Initial experience with the unit in operation showed a noticeable improvement in compaction combined with reduced energy consumption and a measurably reduced noise level.
