Calculation of probability of establishment of temperature cracks in monolithic road concrete
Journal Title: Вісник Одеської державної академії будівництва та архітектури - Year 2017, Vol 1, Issue 66
Abstract
The article shows that in the cement concrete road except for mechanical loads and liquid aggressive media operating temperature. Especially this is dangerous in the summer, when the surface of concrete can be heated to 55 ° C. As a result, the effect of temperature within the concrete, or on its surface may occur temperature cracks. The calculation of the probability of crack under the influence of temperature. Defined boundary conditions for the appearance of temperature cracks and temperature gradient at which it occurs. It is shown that with a difference in temperature inside and on the surface of concrete equal to 26.3 ºС, a crack may appear. Spend the timing in which the danger of occurrence of a crack. This time is 8.3 hours. To combat against the formation of temperature cracks, it is proposed to water the concrete surface with water.
