The engineer on our current project did not specify a minimum concrete temperature, the spec says to place concrete in accordance with ACI-301-05. The answer is an easy one during the prescribed 'cold weather' but if we are not in cold weather concrete (1)is there a minimum temperature r...
The timetmat whichPmoccurred, represented the time when the curve dropped to a minimum and before increasing as a result of the onset of hydration. The timettat whichPtoccurred, marked the time when the kinetics of hydration transition changed from the setting to the hardening stage. To ...
temperature is selected as the average temperature of the highest pavement for seven consecutive days. The minimum pavement design temperature is the minimum pavement temperature expected over the life of the pavement. The maximum and minimum pavement design temperatures plus an average of 4°C are ...
The type of aggregate used in concrete can have significant effects on its thermal properties. The thermal properties of concrete, such as thermal conductivity, thermal diffusivity, and specific heat capacity, play a crucial role in determining how concrete responds to changes in temperature30. The ...
Some rock-forming minerals also exhibit thermal anisotropy, expanding more in some directions than in others, which can sometimes accentuate the differential stresses arising from temperature changes. Senior and Franklin325 also found that hysteresis during thermal cycling can cause irreversible ‘growth’...

This resistivity model can be used to determine the concrete electrical resistivity at any curing time and under different temperature conditions. Therefore, the equivalent age can be obtained by setting the development process of concrete resistivity under standard curing conditions as the reference and...

[14]. The compressive strength of mixed CDW crushed to an average particle size of 92.1 μm could reach 43.9 MPa after curing at room temperature, identified as general-purpose cement in ASTM C1157. The compressive strength of concrete produced with the cementitious material, which allowed ...
Before the testing, the samples were removed from the ethanol solution and dried in an oven until a constant mass was reached with a setting temperature of 55 °C to protect the hydration products from destruction [70]. The MIP method is based on the principle that concrete cannot be wetted...
