Abstract:The purpose of this research is to examine the resistance to repeated freezing and thawing cycles of non-air-entrained and air-entrained concretes containing high dosages of condensed silica fume. Testing was carried out on a total of 76 air-entrained and non air-entrained cylindrical specimens. The compressive strength and the complete stress-strain curves of the specimens under uniaxial compression were determined from different freezing and thawing cycles. The influence of the treatment on the shape of the stress-strain curves was investigated. In addition, the dynamic modulus under the same cyclic conditions was determined. To investigate both the spacing factor and the specific surface, the air void and pore structure characteristics of hardened specimens were studied.
