Abstract

The invention discloses a method and device for analyzing the temperature gradient limit of mass concrete. At various ages of mass concrete, the acceptable maximum temperature gradient limit is calculated according to different positions and depths without cracks. According to this The temperature gradient limit can make a more reasonable concrete maintenance plan, improve the maintenance quality under the condition of low investment, and achieve the effect of controlling the development of temperature cracks. The temperature gradient limit of different depths of mass concrete at different ages is used for mass concrete construction In temperature monitoring, a more reasonable mass concrete maintenance plan can be formulated based on this, so as to realize quantitative prediction and prevent the occurrence of harmful cracks.

Description

technical field [0001] The present disclosure relates to the field of concrete construction, in particular to a method and device for analyzing the temperature gradient limit value of mass concrete. Background technique [0002] In actual engineering, the control of temperature cracks in mass concrete construction mainly relies on manual monitoring and professional experience. It is based on the regulations of my country's mass concrete construction code: the temperature difference between the inside and outside of the concrete pouring block (excluding the equivalent temperature of concrete shrinkage) should not be greater than 25 °C. This temperature difference is used as the criterion for concrete cracking. [0003] Practice has proved that if it is simply considered that the internal and external temperature difference caused by the heat of cement hydration in mass concrete cannot exceed the 25°C specified in the code, as a criterion for the concrete not to crack, there ...
