to be within a range of 50°F to 90°F (10°C to 32°C). However, different specified limits are provided depending on the element size and ambient conditions (ACI 301,207). The temperature the concrete exhibits during placement affects the temperature of concrete during the next hydration...
This research describes the dynamics of PMMA in terms of atomic interactions, with the objective of understanding how high temperatures and exposure to moisture cause degradation. The study covered a range of temperatures relevant to 3D-printed PMMA dental materials and included different temperature ...

wherea(T) is an unkown function of the temperatureTwhich we will refer to in the rest of this manuscript as the “slope”. Nevertheless, (I) It is not clear how universal the form in Eq. (2) is, in which range of energies it emerges, and if it holds at any temperature; ...
The results obtained from this study indicate that the residual resistance is reduced with the rise in temperature for all the concretes studied, except in the temperature range of 300 °C, in which a slight improvement in resistance is noticed. The incorporation of PET fibers in the test ...
Previous works [7] have reported a higher mass loss in this temperature range, which can be explained—along with the differences in binder chemistry—by the curing conditions (50 °C for 3 d) and curing duration (28 d) prior to thermal testing employed in this work. Thus, part of the...

Such concrete should be optimized to account for variations in workability due to ambient temperature. SCC workability has been shown to be highly dependant on temperature, elapsed time, and type of high-range water reducing admixture (HRWRA). Variation of rheological properties of SCC during......
