SEPCO III is a national level project at Port Qasim Karachi with 2 units of 660MW coal fired plants in Karachi. The construction of the project started in 2015 and concluded in 2018.
Project Requirements
The project involved several complexities, which include:
- The height of the cooling towers and chimneys needed to be fair faced
- Water tight concrete for sea water intake channels
- Heavy pressure resistance by concrete
- High flowable, high strength non-shrink grout
Proposed Solution
The requirements of the project were a real challenge and the approval process of the product was very complex, with high-level requirements that needed to be met without wasting time and spending more cost. For concrete to be fair faced and water tight, Vertex Chemicals used G909 admixture in bulk quantities, ensuring that it meets all the project requirements flawlessly.
Furthermore, non-shrink grout solutions were created using cementitious grout V1/50 that is workable as well as flowable with high strength setting.
Conclusions
The project was one of its kind with several hurdles such as maintaining workability of concrete, making it water tight, sealing the surface, grouting of different portions with non-shrink grout etc. However, all the requirements were met and the project was completed without any delay.
