Mechanické aktivace příměsí do betonů a ověření dopadů na fyzikálně-mechanické vlastnosti čerstvých a zatvrdlých betonů / Mechanical activation of admixtures in concrete and verify the impact on physical and mechanical properties of fresh and hardened concrete

This work is devoted to describe the possibilities of mechanical activations of admixtures used in concrete. Then, the verification options of grind fly ash, both from brown and black coal, from the classical as well as fluidized combustion and examination their impact on physical and mechanical properties of concrete, especially on long-term development to old age 180 days. Further attention is paid to assessing the impact of the use of mechanically activated fly ash on hydration heat evolution and the associated volume changes in the age of 1 to 90 days. In this work are presented the results of basic technological tests on concretes using admixtures, especially fly ash.
