FROST RESISTENCE OF HIGH STRENGTH CONCRETE ON PRELOADING FLEXURAL STRESS

Concrete damage is the result of the multiple action of many factors. This paper presents the effect of external flexural load on the frost resistance of high strength concrete with and without air-entrainment. The preloading flexural stress range from 0 to 50 percent of the modulus of rupture of specimens. It is shown that the damage to concrete specimens with high level preloading stress is primarily caused by stress concentration where the microcracking is initiated by freezing-thawing cycles. Freezing-thawing cycles is the main reason for the damage of concrete specimens with low level preloading.
