Concrete Science Research Brief: Toughness Simply by Scratching

January 1, 2011

Scratching a weaker material with a tougher one is no doubt the most elemental conceptualization of a materials test ever conceived by mankind. This research highlights the relevance of the scratch test for assessing fracture properties of cement-based materials at multiple scales. This research makes it possible to identify reserves in concrete design that could enhance the crack resistance of concrete materials. Moreover, the test can be conducted over a period of time on the same sample that provides a benefit of evaluating the evolution of properties with time. All this makes the scratch test most appealing for innovative concrete applications. MORE
