Concrete Solutions for Southern Africa
Designed to suit the interests of the South African concrete and precast industries, ICCX Sun City, held from 19.02 – 21.02.08 at Sun City resort 2 hours drive north of Johannesburg, attracted close to 600 visitors. With 80 exhibiting companies the event featured the largest ex- hibition on concrete manufacturing technology that ever took place in Sub-Saharan Africa. Preceding the ICCX, a technical course on the design of precast concrete frame structures was held, attended by about 100 local engineers and architects. The visits to the precast plants and construction sites of the Gautrain, currently Africa’s largest construction project, rounded of the programme.
The ICCX events, which are now taking place regularly in Russia, South Africa and selected other countries, address the growing economies worldwide and aim at informing the concrete producing industry about new trends and developments in the international market. The mixture of technical conference and trade exhibition enables suppliers and users of concrete materials, production technology, and related services to establish and strengthen relationships and business contacts. The second ICCX in South Africa saw a significantly increased number of participants, compared to ICCX Cape Town 2007, mirroring the local trend towards application of modern production technology.
Trade exhibition with 80 local and international exhibitors
The conference was designed to offer a balanced mix between the presentations on selected topics and the trade exhibition showcasing practical aspects of concrete manufacture and application. With a total of 80 exhibiting companies the exhibition offered a comprehensive insight into modern concrete production technology and associated branches of the industry. The exhibitors presented their range of products from the fields of plant technology, mixing and formwork technology, transport and handling systems, special concrete products, cement extenders, admixtures, pigments, connection and fastening systems, placing technology, and reinforcing steel. The exhibitors were generally very satisfiedwith the success of their participation, which is a result mainly of the high quality of the conference participants, most of which were members of the local concrete producing industry.
The local supporters and sponsors helped to make ICCX Sun City a great success. The event was supported by the leading South African industry representatives, namely the Cement and Concrete Institute (C&CI), the Concrete Manufacturers Association (CMA), the Concrete Society of Southern Africa (CSSA), and the South African Readymix Association (SARMA). The 4 sponsors of ICCX were Sika South Africa, BASF, Pretoria Portland Cement and Mapei, whose contribution and assistance in organising proved to significantly add to the success of the event.
Concrete Solutions for Southern Africa – designed for a booming industry
"Concrete solutions for Southern Africa" was the motto of ICCX Sun City 2008. The selection of topics for the technical presentations was made in close cooperation with the local industry representatives. In good ICCX tradition, leading experts from around the world were invited to present their experience on those topics. In addition, the leading engineers involved in the largest construction projects in South Africa were present to discuss the latest developments relating to the Gautrain and the 2010 Soccer World Cup. In total, the conference featured 20 presentations by local and international speakers. The categories of topics included concrete technology, precast concrete, architectural concrete, precast technology for the infrastructure, and paving technology.
Day 1: Concrete technology, precast concrete, architectural concrete
The CPI-worldwide team, consisting of Dr. Holger Karutz (editor-in-chief), Gerhard Klöckner (publisher) und Dr. Hans-Dieter Beushausen (CPI-Südafrika) welcomed the delegates and handed over to Professor Mark Alexander from the University of Cape Town, who chaired the first session. In the first presentation, Martin Clarke, Chief Executive of British Precast, discussed the market advantages of precast concrete technology from a client and users point of view. The second lecture became a little more technical when Arnold van Acker presented various modern techniques, design guidelines and application fields for prestressed concrete. Sean Flanagan and Ian Thoms, leading engineers of the Green Point Soccer Stadium in Cape Town and the Gautrain, respectively, gave an overview on the use of precast technology in these projects and discussed latest developments and challenges, thus offering a good insight into the local booming industry. Presentations concerning concrete technology covered the topics of modern mixing technology, concrete admixtures (Dr. Frank Dehn, Germany), modern formwork technology (Andrew Rowe, South Africa), general trends and developments in concrete technology (Bryan Perrie, South Africa) and fibre reinforced concrete (Professor Gideon van Zijl, South Africa). Patrick de Clerck (Belgiun) and Hugh Fraser (South Africa) discussed application and design of architectural concrete world wide.
Day 2: Low-cost housing, production technology, concrete products
Low-cost housing technology is a very important topic in South Africa. This topic was discussed by Dr. David Fernandez- Ordonez (Spain) and Christian Prilhofer (Germany). Dr. Michael Khrapko (New Zealand) presented a comprehensive overview on tilt-up technology, a technique that is being increasingly applied not only in South Africa. Important issues to be considered in precast production are health and safety aspects. These were covered in a presentation that explained the health and safety principles applied in the German construction industry and which have helped to drastically reduce safety hazards and accidents (Helmut Ehnes, Germany). Professor Mark Alexander (South Africa) addressed material technology and design considerations for the prevention of common durability problems experienced by concrete pipes. Graeme Hume (Australia) shared his experience with the production of concrete masts and poles and discussed new design production and manufacturing techniques for elements with large dimensions. The session on concrete paving technology covered the topics design of permeable paving (Brian Schackel, Australia), industrial manufacture of concrete block paving (Dr. Steffen Mothes, Germany) und testing of concrete block paving (John Cairns, South Africa).
Nature and culture – an exiting social program
The Game Safari in Pilansberg National Park, which was preceding the ICCX, was attended by 150 delegates and offered an unforgettable African experience, which was rounded off by a dinner under the clear African sky in the bush, during which great food and excellent entertainment could be enjoyed. The evening function of the ICCX on the following day took place in the Valley of Waves in Sun City. Delegates were seated along the beach of the resort and experienced a rather unconventional conference dinner, once again under the clear sky.
Gautrain – Visit in Africa’s largest precast plant
Following the ICCX, plant and site visits were organized, exposing the delegates to the manufacturing plants and construction sites of the Gautrain, currently the largest construction project in Africa. The project includes the manufacture and installation of viaduct elements, prestressed M-beams and tunnel lining segments. The project is de- scribed in detail in another publication in this issue of CPI.
ICCX Johannesburg 2009
Based on positive feedback from exhibitors, delegates and sponsors during the event, another ICCX is likely to take place in Johannesburg, South Africa, in September 2009. As such, the time of the next event in this region is promising to be very exciting, as South Africa’s construction industry will be extremely busy finalising the projects for the Soccer World Cup 2010. ICCX Johannesburg 2009 – CPI will keep you informed.
