The dependence of the shrinkage of the cement composite with fine ground recycled concrete on its microstructure

Popis výsledku v původním jazyce

This paper is focused on the shrinkage and microstructure of composite cement based materials with different percentage of fine ground recycled concrete. Recycled concrete is in cement mixture as a partial replacement of the filler, which under certain circumstances also functions as a binder component. Images were used for the assessment of the microstructure from the optical and scanning electron microscope. There were produced four mixtures of cement pastes containing 0, 33, 50 and 67 wt. % of fine ground recycled concrete. At the conclusion of the experiment it was shown that the mixture samples with increasing amounts of recycled concrete have greater shrinkage due to the increased water/cement ratio, which is for the individual mixtures different in the terms of the same workability of all mixtures.
