Concrete is by far the most widely used building material in the world. Using a novel concrete formula, an Empa team has succeeded in producing self-tensioned concrete elements – with CFRP. Thanks to a special recipe, the concrete expands as it hardens. As a result of this expansion, the concrete puts the CFRP bars in its interior under tension and thus automatically pre-stresses itself.
