Abstract EN
The variation of concrete pores under the action of freeze-thaw cycles was investigated experimentally by using the X-ray CT.
Firstly, the statistical characteristics of pores of concrete specimens were obtained by using the X-ray image analysis.
Secondly, the variation of porosity and pore volume of concrete pores were analyzed and discussed by comparing with above characteristics.
Thirdly, the failure process of the concrete specimens acted by the freeze-thaw cycles was investigated by scanning the interior of concrete specimens.
The results showed that the pore volumes of concrete pores whose volumes were located at the interval [0.5 mm3, 20 mm3] have no big variation in both the amounts and volume of concrete pores, while others were found to have huge change during the process of experiment.
The extent of damage acted by the repeated freezing and thawing gradually ranged from surface to complete disintegration of the interior of concrete specimens after 30 cycles of freeze-thaw acting.
