AB Concrete is a basic building material. This article describes its properties. Microcracks result from volume changes in concrete. The intensity of temperature development and the way concrete is being cured have a significant influence on the emergence of microcracks. Indeed, the quantification of microcracks isn't simple. Using acoustic emissions it is possible to observe the evolution of scratches in hardening concrete - how many of them evolve and how the intensity of their emergence changes depending on different regimes of curing or different types of concrete (different cement batches, various additives and admixtures, etc.).
