Tunnels are a many-splendoured thing. For motorists, they often impress with their seemingly endless length and the remote locations they so seamlessly connect. Water and mountains are no [...]
Does EFNARC (Experts for Specialised Construction and Concrete Systems) certification ring a bell? Would you like to learn more about this important organization in the world of shotcrete? Great, [...]
We can’t stress this enough: if you want your shotcrete equipment to function optimally, you’re going to have to devote a little time and effort to it. And by little, we mean little. Because in [...]

Another essential test to measure the consistency of fresh shotcrete is the slump or Abrams cone test. As is the case with the flow table test, the methodology is simple and requires only basic [...]
Underground worksites such as mines and tunnels are tough and dangerous workplace environments: so much so that a small oversight can turn into a massive issue down the line, particularly when [...]
Training requirements for shotcrete operators are increasingly demanding, given the importance of this work onsite. A poor application technique not only generates greater shotcrete waste as it [...]
Tests have a vital role to play in the mixing of shotcrete, with on-site sampling and testing essential to ensure the sprayed concrete offers the best possible quality and performance. The two [...]
A School of Mines with an underground site where operators can practice concrete spraying or shotcreting is an essential part of the practice-based nozzleman learning process. Underground [...]
