The Concrete Institute’s School of Concrete Technology will this year offer a special one-day course for concrete batchers and batch plant staff in Johannesburg, Durban, Cape Town and Port Elizabeth.
Matthews Magwaza, lecturer at the School of Concrete Technology, says batching – the process of measuring and combining concrete ingredients according to the predetermined mix design – is a vital element of concrete production which ensures high and uniform quality of readymix concrete for each batch produced by a batching plant.
“The durability of a structure is highly dependent on the quality of the concrete used to build it. Therefore, it is essential to precisely and meticulously select the concrete ingredients and this can only be achieved by a competent batcher. It is, for example, important to maintain the water-cement ratio constantly at the set value and a skilled batcher will be able to adapt his or her production to cater for the water content in the aggregate,” Magwaza explains.
He says proper batching offers several benefits including:
- Low variability in plastic and hardened concrete properties;
- Better plant efficiency;
- Lower production costs; and
- Higher client satisfaction and sales volumes.
“The course offered by the School of Concrete Technology will provide batchers and staff at a batch plant with the essential concrete education and theory to competently produce quality readymix concrete. The training will also benefit batch plant supervisors, laboratory staff, sales and staff and even general labourers involved with batching,” Magwaza adds.
Topics covered will include:
- Batchers’ responsibilities;
- The concrete materials and their effect on the concrete mix;
- Fresh properties of concrete - and the tests to check it;
- Basics of mix design, including the control of the water content;
- Testing for the hardened properties of concrete; and
- Basic management of a batch plant, including implement Quality Control systems.
The course (SCT15) will be presented in Midrand on June 23, Durban on July 20, Cape Town on September 14, and Port Elizabeth on October 5. For further information, contact John Roxburgh on 011 315 0300 or email email@example.com
