The diploma thesis deals with the determination of the influence of the maximum density of the cement matrix on the volume changes of concrete, the influence of different admixtures or their combinations on the development of hydration temperatures and on the water separation of concrete. The theoretical part describes the various types of volume changes of concrete, the effects of individual input components and mineral admixtures on water separation, hydration heat development and concrete microstructure. The experimental part is focused on monitoring not only the volume changes of concrete mixtures made using different types of admixtures or their suitable combination until the age of 60 days of maturation, but also the influence of their use on selected mechanical parameters of concrete such as compressive strength, concrete in its fresh state and monitoring changes in the microstructure from long-term aging mixtures.
