Reinforcement of sprayed concrete for the Mining Industry in South Africa
For permanent sprayed concrete linings, reinforcement is also installed to avoid the development of cracks in the concrete due to shrinkage, as concrete shrinks and is restrained at the same time, as well as to mitigate temperature stresses.
Sprayed Concrete Testing of early strength development in Mining Industry South Africa
Various laboratory tests with cement paste or standard mortar tests are carried out to verify the performance of selected cement and admixture interactions.
Sprayed Concrete Design Optimization - The Composite Shell Lining | South Africa
It is a further development of the single shell lining system, and consists of two concrete linings, primary (outer) lining and secondary (inner) lining, and a double-bonded spray-applied waterproofing membrane embedded between them.
Key elements of Sprayed Concrete At Batching Plant and On Site | South Africa
Due to its nature as a spray-applied material, sprayed concrete offers excellent surface sealing and ground strengthening as it perfectly fits the excavation contour, hardening and gaining strength in a remarkably short time frame.
Sprayed concrete - Mix Design and Durability | Mining South Africa
Creating the optimal concrete solution requires experienced concrete knowledge. Suitable materials for the mix (cement, aggregates, superplasticizer, etc.) and the correct alkali-free accelerator must be chosen to optimize pumpability and spraying performance.
Is Sprayed Concrete – the Most Important Element in Mining Ground Support?
Sprayed concrete technology has revolutionized tunnel construction and mining operations since the middle of the 20th century.
