Water as sprayed concrete constituent material in Mining Industry | South Africa
The quality of the mixing water for production of concrete can influence the setting time, the strength development of concrete and the protection of the reinforcement against corrosion.
Typical properties and parameters of sprayed concrete
Cement as sprayed concrete constituent material in Mining Industry
Cements shall fulfill the requirements of EN197 or alternatively comply with the national standards or regulations valid in the place of use of the sprayed concrete. Only cement with recognized suitability for sprayed concrete applications shall be used.
Sprayed Concrete Mix Design for the Mining Industry in South Africa
Mix proportions shall be chosen to satisfy all the performance criteria for fresh and hardened concrete, including consistence (if wet-mix), density, strength, durability, and protection of embedded steel against corrosion.
Polymer fibers in concrete environment | Mining South Africa
Polymer fibers are very efficient at distributing micro-cracks during the plastic phase of hardening and they also help to reduce rebound in wet-mix spraying.
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.
