Полученные результаты указывают на возрастание прочности и энергии разрушения образцов при температурах от 20 до 300 °С. Подтверждено положительное влияние высокой температуры (до 400 °С) на механические свойства бетона с водоцементным отношением менее 0,3. Экспериментально доказано, что использование в высокопрочном бетоне минералогической добавки типа «микрокремнезем» в условиях высоких температур приводит к взрывному растрескиванию каждого третьего образца. Изменение вязкости разрушения, трещиностойкости, удельных энергозатрат на квазистатическое разрушение описывается математическими выражениями.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents experimental results of mechanical high strength concrete (HSC) properties at high temperature. The obtained results specify an increasing of strength and destruction energy of samples at temperature from 20 °С to 300 °С. The positive influence of high temperature (up to 400 °C) on concrete mechanical properties with w/c ratio less than 0.3 has been proved in the paper. The paper has experimentally proved that usage of a mineralogical additive as «silica fume» in high strength concrete at high temperatures often leads to an explosive destruction of every third sample. Changes in fracture toughness, crack resistance, specific energy consumption on quasi-static destruction have been described in mathematic formula.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Милованов, А.
