Of course it does. One thing can be said about air entrainment everything affects it in concrete. High temperature can lower the effectiveness of air entrainment products. Typically requiring a higher dosage of air entrainment to get the desired air content.
-Re-inforced cement concrete -High temperature services
to offer high resistance in tansion,shear and bond
silica fume and quartz powder is added to make the concrete more denser. fine aggregates fill the voids between coarse aggegates, cement fill the voids between fine aggregate, silica fume fills the voids between cement and quartz powder fills the voids in between silica fumes
Concretes from grade M-60 to M-80 are called as high strength concretes as per IS 456-2000
aggregates are used to concrete for following purposes: 1.if totally binding materials like cement is used in concrete, the cost of concrete will be high which is uneconomical. 2.to prevent high shrinkage of concrete mix fine aggregates are used. 3.to increase the volume of concrete mix aggregates are used.

High temperature makes the volume greater.
Sublimation is accelerated at high temperature.
Depending on the composite of the concrete material, it can melt at different temperatures. When concrete reaches a high enough temperature such as more than 1000 degrees Celsius, it can crumble like sugar.
At high temperature the solubility is increased.
Concrete is not combustible, although different types will be damamged by varying amounts of heat. If the temperature is high enough.
if it is high the density is high so if the temperature is low the density is low.
High temperature shortens battery life.Freezing a battery can kill it.
Yes, high temperature favors evaporation.
