| Special made Moulds are greased with a purpose made concrete de-moulding grease and high tensile strands are tensioned to 1700 Kpa into moulds which are barrel wedged at end blocks capable of withstanding forces of 600 000 Kpa.
Tensioning, wedges, barrels and strand quantity is rechecked by factory manager on duty. Setting out of prestressed beam lengths are then measured and checked according to production plan process prior to stage 1 passed for casting. Concrete batching is stage 2 of quality control, all raw materials are prepared in quantity from 52.5 N cement to granite crusher and stone to be used in concrete mix needed for casting into moulds prepared and passed for cast. Stage 3, All materials are proportionately mixed in 500 liter concrete mixers with slump care taken throughout entire process of mixing. Stage 4 The result is 45 mPa strength of concrete mix poured into moulds during which optimum concrete vibration is done. The concrete casting process involves minimum 12 qualified concrete staff and 2 quality control managers. Stage 5 Shear connectors bend prior to cast is placed into wet mix after mould cast, prior to texture faced into top of concrete. Stage 6 After this is done both managers re-check production and log times sheets temperature start and complete figures materials used and spill estimated. Stage 7 The production sheet is then issued to factory manager for production activity. The prestressed beams are now in a process of cure and monitored in temperature controlled covers. |
