Abstract

KUDELA, M. Effect of the temperatures of fresh sprayed concrete and accelerators on the strenght development of young sprayed concrete. Thesis. Ostrava: VŠB – Technical University of Ostrava, Faculty of Civil Engineering, 2015. 95 s.

The thesis is focused on examining the influence of the temperature of the shotcrete and the accelerator on the development of its strength. The first part describes the use of shotcrete, as well as the requirements imposed on it. The next chapter deals mainly wet spray technology, which today covers 70% of the world production of shotcrete. Followed by testing methods and a description of the experiment. Results and evaluation are clearly presented in the form of tables and graphs based on the findings. At the end of the work, we evaluate and compare the results and recommendations for the use in construction practice.
