Polymer-modified sprayed concrete from Wacker Chemie AG

Whether in tunneling, mining, hydraulic engineering or road construction, the application of sprayed concrete entails rebound – a significant time and cost factor. For this reason, Wacker Chemie AG developed a new line of polymeric binders for concrete applications that considerably reduce spray rebound – and at the same time optimize the concrete’s properties.
An important quality factor in the performance of sprayed concrete is rebound. Rebound alters its properties, and the excess material cannot be reused but must be disposed of as waste. Reducing rebound is therefore important for both...
