Research of Heat Treatment of Cement Used in Construction of Bridge Transition Through Kerchen Strait

Abstract: Введение. В статье рассматриваются вопросы, связанные с исследованием тепловыделения цементов, применяемых при строительстве мостового перехода через Керченский пролив. Данный вопрос представляется актуальным ввиду строительства указанного объекта в условиях сухого жаркого климата. Материалы и методы. Исследование проводилось в условиях реального времени с применением современных информационно-аналитических систем, позволяющих получить результаты, максимально приближенные к реальным условиям. При обработке дан… Show more

“…Due to the fact that numerous microcracks and pores are formed during the firing of the clinker, the cement grains have an increased free surface on which the hydration reaction can take place. When wetting such cement grains with water, a large number of hydration products are formed in short intervals, an intense structuring begins, accompanied by intense heat generation [4,5]. In the absence of experimental data, the heat generation of concrete in thermal calculations is usually determined based on the mineralogical composition of the cement used to prepare concrete [6,7,8].…”
