SHRINKAGE OF HARDENED CEMENT PASTE AT TEMPERATURES UP TO 670 C (1238 F)
The transient and ultimate shrinkage behavior of unsealed hardened cement paste of water-cement ration (w/c)=0.3 was investigated for maximum exposure temperatures up to 670 C (1238 F) and a heating rate of 1 C/min (1.8 F/min). The shrinkage phase, the duration of which was dependent on the maximum exposure temperature, was modeled mathematically using a combined logarithmic and exponential expression. The amount of shrinkage experienced and the temperature at which the trend of increasing ultimate shrinkage is reversed was found to depend on the w/c ratio.
