The sustainable building material could replace concrete in non-load-bearing structures as well as in load-bearing walls of residential buildings. For large-scale use, Bernard and her team want to define standards for composition and mechanical strength. On the other hand, additives must be found that increase the load-bearing capacity of the material. Conventional cement is currently still used here, but this pushes the ecological footprint of clay &ldquo;back into the red zone&rdquo;, Empa writes.<\/p>\n<p class=\"bodytext\">Bernard, in collaboration with geologist Raphael Kuhn, has found a promising approach in magnesium oxide. In initial laboratory experiments with clay formulations, a compressive strength of up to 15 megapascals was achieved, Empa informs. Clay with added cement achieves up to 20 megapascals.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Empa researcher Ellina Bernard is working to establish clay as a sustainable alternative to concrete.
