Concrete Industry Personalities

Cyril Attwell and Fanie van Tonder:

masterbuilders.co.za recently published a news article in two parts that first appeared in “Concrete Trends” entitled “Classified Fly Ash Contributes to World-Class Gautrain Concrete. Concrete Industry personalities who feature in the article include Cyril Attwell and Fanie van Tonder:

Cyril Attwell
is research manager at Murray & Roberts (a BCJV partner). He is an analytical chemist by training and today a highly regarded concrete technologist and research scientist. Attwell estimates that he has done mix designs for 5 000 projects around the world, from shopping centres to dams and petrochemical facilities. The ARC technology being used for Gautrain was also applied at a Murray & Roberts precast sleeper factory at Beit Bridge. “We reached a 0,38 water:cement ratio using an expensive superplasticiser and moved to 0,5 with ARC achieving the same strength. The technology has enormous potential,” comments Attwell. “Synergy and balance between components is the key.”

Fanie van Tonder
is precast yard manager for Bombela Civils Joint Venture. Previously a Group Five director, he was involved in building Sasol 2 and 3 at Secunda; mines for Iscor and platinum companies, and has worked in Iraq, Ghana, Angola (petrochemical project in Luanda) and Kabinda, DRC (a major oil and gas separation project). While he has experience with most building materials, he loves concrete and has a keen eye for quality.
