Abstract

Concrete is one of the most widely used construction materials in the world [1] so it is crucial to understand its behaviour under failure. However this is not always the case, since models to predict shear failure are not su ciently general, for instance. This implies that structures must have additional safety factors in order to account for the possible failure, requiring extra material for the concrete structure. Part of these problems come from the heterogeneity of the concrete at the microscale. It is formed by different materials (sand, aggregate, cement) that can greatly di er in size, which means that microcracks are likely to appear among the larger aggregate. Additionally, concrete is weak in tension, so reinforcements (such as steel) need to be incorporated to concrete structures to increase its resistance for tensile loading. Conventional models for concrete try to take these factors into account, but they still have limited use.
