✦ Synopsis
Normal Portland cement concretes with a water-cement ratio of 0,3 and concretes containing 9% condensed silica fume (CSF) at a water-cementitious material ratio of 0,3 were submitted to freeze-thaw cycles in water in accordance with ASTM Standard C 666. The CSF concretes were also submitted to freeze-thaw cycles in air at 100% relative humidity.
For both types of concrete and both types of test, the values of the critical air void spacing factor were found to range between 300 ~m and 500 ~m. Air entrainment was thus needed to protect these concretes from frost damage.
