Concrete.TV interviewed Anton Weavind, founder of Mamba Cement who makes a case for going back to the old practice of producing pure cement concrete. Currently in South Africa, the standards show a lot of variability in the capacity of the cement producers to change their product to a certain extent to their own benefit. • Weavind criticizes, for example, in the 42.5 or 52.5 instance, the cement producer is allowed to add up to 5% limestone. He believes this has a serious knock on effect to concrete producers. • The cement producer is able to sell his product at a margin of pure cement, even though the concrete producer has to add 5% more cement in the concrete mix to come to the same result. Weaving compares this to selling coca-cola with water in it . • Mamba Cement was founded in reaction to the cement shortages that affected South Africa in 2008/2009. Construction of the plant commenced in January 2015 and it will target the production of 1 million tons a year. Mamba’s main footprint aims to provide to the Pretoria/Gauteng, Rustenburg, Limpopo and Mpumalanga areas. The plant is currently 5 months ahead of schedule. • Weavind says 1 million bags of cement per month which will be distributed into the hardware industry. They will make about 70 000 tons of pure bulk cement a month which will be targeting the concrete industry, construction and the cement blending industry. • The majority shareholders of Mamba Cement are the Jidong Development Group from China, Wiphold and the debt was provided by Nedbank. • When asked about using local employment, Weavind stated that 70% of the work force will be South African, and that extensive training programmes are in place, with personnel receiving knowledge transfer from the Chinese. • ======================================= • www.Concrete.TV • Facebook: https://www.facebook.com/pages/Concre... • Twitter: @_concretetv • www.Concrete.TV – a dynamic blend of broadcast style television and WebTV, covering: news, projects, products, people, countries and events for the concrete and construction industry. • ======================================= • [Limestone in concrete 'only adds value to cement producers pockets'] • [ • Limestone in concrete 'only adds valu... ]
