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
Yes, you can mix concrete with soft sand, but it's generally not recommended. Soft sand may lead to a weaker mix due to its high silt content, which can affect the bonding properties of the concrete. For optimal strength and durability, it's better to use well-graded sharp sand or coarse aggregates specifically designed for concrete mixes.
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
80
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.
High temperature=low viscosityLow temperature=high viscosity

High temperature makes the volume greater.
Concrete is not combustible, although different types will be damamged by varying amounts of heat. If the temperature is high enough.
At high temperature the solubility is increased.
High temperature shortens battery life.Freezing a battery can kill it.
Yes, high temperature favors evaporation.

A high temperature will make it spontaneous.
