Summary/Abstract: Optimizing the properties of the concrete mixture and the finished concrete is a task that has been on the agenda ever since the discovery of this popular building material. Different substances and mixtures are developed and improved, so-called additives to concrete that give it greater strength, better plasticity or adjust the setting times. These additives are thoroughly researched in construction laboratories, and their properties and effects are analyzed in various practical directions. The article presents the main principle of action of the main chemical additives used at the moment, the mode of action and the methods of their testing.
