Abstract:A one-cycle freezing test, involving length measurements during freezing, is used in an attempt to establish limiting maximum water-cement ratios for concretes for different exposure conditions. Mortar prisms were cast from a series of mixes, (both air-entrained and non-air-entrained) covering a range of water-cement ratios from 0.40 to 0.70. After being moist cured for 1 month the prisms were then conditioned to various degrees of saturation (to simulate different exposure conditions) and subjected to the freezing test. Frost susceptibility of the various mixes was determined from the length change patterns produced in the freezing test. Critical degree of saturation was found to be approximately 90 percent. Air entrainment was found to provide protection up to a water-cement ratio of 0.58.
