At present, the research on the basic properties and freeze-thaw damage characteristics of the modified soil is mainly conducted by test under the conditions of temperature change and frost-thaw cycle (Lai YM.
Antipermeability and antifrost tests were carried out by adopting rapid chloride migration (RCM) method and rapid freeze-thaw method, respectively, all specimens were cured 28 d under standard conditions (temperature: 20 [+ or -] 2[degrees]C, relative humidity: >95%), and the test procedures are described clearly elsewhere [19].
For years, we've never noticed any consistent trend in Ct value changes over five freeze-thaw cycles," the defenders of such a policy might say.
The tubes' small volumes allow for multiple aliquots of individual samples, avoiding freeze-thaw cycles.
To study the influence of freeze-thaw cycles, samples were thawed up to 4 times and (re)frozen at -80 [degrees]C.

The 13 papers cover freeze-thaw effects on mechanical properties, testing mechanical properties, mechanical properties, and the classification and effects of mechanical properties on performance.
It demonstrates good performance across multiple paint formulations improves tint strength development over key APEO benchmarks and maintains freeze-thaw stability in paints.
The analysis of scientific, especially technical and practical literature on this issue has revealed that the mechanism of concrete degradation caused by cyclic freeze-thaw conditions and de-icing salts is not entirely clear.
It should be noted that salt scaling is not the same as freeze-thaw damage, which is characterized by the reduction of the entire structure strength, because superficial scaling of concrete initially causes no threat to mechanical integrity of concrete.
The collaboration will involve three phases and is intended to investigate the effects of multiple freeze-thaw cycles on DNA from whole blood, both fresh and archived.
