This might involve the use of insulation blankets, heated enclosures, or temperature-controlled water to encourage proper curing. What temperature is too hot to pour concrete? Concrete can be poured in hot weather, but extreme heat will deliver a new set of challenges. Temperatures above 90 ...
Why Monitor Concrete Temperature? In Phase II, the temperature of concrete can be measured as it is poured. Temperature is typically measured to make sure the concrete is in compliance with certain specifications that define an allowable temperature range. Typical specifications require the temperature...

When temperatures are raised from 100 to 200 °C, the material properties of the cement past raised begins to lose its stability due to a weak physical chemical reaction. In this temperature range, the evaporable moisture plays a dominant role in reducing cohesive forces between C-S-H layers ...
On the other hand, shrinkage is another kind of deformation which is independent of load but closely related to the temperature and restrain conditions [123]. In fact, the total strain of the concrete at the time t (ε(t)) shall be evaluated as a summation of the strain due to the ...
range from 1000 to 1200 degrees Celsius, resulting in substantial mass loss and a notable decrease in mechanical strength7. It is worth emphasizing that the choice of aggregates in the concrete mix plays a pivotal role in compressive strength reduction following high-temperature exposure. Siliceous ...
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......
