Abstract:

In order to study the mechanical properties and energy evolution of low-temperature concrete during uniaxial compression, a uniaxial compression test was performed on concrete. In addition, the evolution laws of compressive strength, deformation modulus and total energy, elastic potential energy, dissipated energy and peak energy of concrete in the process of deformation and failure are analyzed. The effects of age and temperature on low-temperature concrete is analyzed from the perspective of energy. Test results show that temperature improves the strength and deformation of concrete to varying degrees. When cured for 28 days, the compressive strength and deformation modulus of concrete at -20 ℃ is increased by 17.98% and 21.45% respectively, compared with the compressive strength and deformation modulus at room temperature of 20 ℃. At the point of failure of the concrete under uniaxial compression, the total damage energy and the dissipation energy both increase, while the developed elastic strain energy increases and then decreases. Increase in curing duration tends to increase the total destruction energy of concrete, peak point elastic strain energy, peak point dissipation energy, and peak point total energy. Whereas increase in curing durations, has shown to decrease the total destruction energy of concrete, the peak point elastic strain energy, peak point dissipation energy, and peak point total energy. The peak point strain energy reflects the ability of low-temperature concrete to reasonably resist damage. By using the principle of energy analysis to study the deformation process of concrete, it provides research methods and ideas for the deformation analysis of this type of material under load.

Key words: low-temperature concrete, uniaxial compression, mechanical properties, energy mechanism, dissipated energy
