Temperatures below boiling point - commonly about 700C, are used to quicken the curing of mass-produced items such as concrete blocks and pipes. This can shorten the curing from a few days to a few hours.
However, in large concrete pours, such as would be found in a mass concrete dam, the heat generated by the self curing process could induce thermal expansion stresses, and this is countered by having cooling pipes installed in the dam body.
Temperatures much elevated, could boil away the water of crystallization from the various crystal processes upon which the concrete depends for its strength. Effectively, you would be 'calcining' the crystals once again!

What happens to concrete when it is heated up?
When concrete is heated up, the moisture trapped inside can turn into steam and cause the concrete to expand rapidly, leading to cracking and spalling. The heat can also cause the concrete to lose its strength and structural integrity. Ultimately, if the temperature is high enough, the concrete can undergo thermal spalling and disintegrate.
What is DELTA T?
Delta T is a term used to represent a change in temperature. It is calculated by subtracting the initial temperature from the final temperature. Delta T is commonly used in various fields such as physics, engineering, and environmental science to quantify temperature differences.
How does temperature effect hydrogen peroxide?
Temperature can impact the rate of a hydrogen peroxide reaction. Generally, increasing the temperature can increase the rate of the reaction as it provides more energy for molecules to collide and react. However, extremely high temperatures can also lead to the decomposition of hydrogen peroxide.
What form of the ideal gas law would you use to calculate the temperature of a gas?
The formula is: T = PV/nR, Where: * T is the temperature in kelvin * P is the pressure in atmospheres * n is the number of moles * R is the gas constant

What temperature does concrete melt at?
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.
Is concrete combustible?
Concrete is not combustible, although different types will be damamged by varying amounts of heat. If the temperature is high enough.

Does high temperature affect air entrainment on concrete?
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.

Can you use high temp concrete in place of a gasket on a wood burning stove t?
Usually, no. Gaskets have some "give" as temperatures change. While concrete is strong, it is brittle.
Applications where tensile strength is the primary factor in material selection?
-Re-inforced cement concrete -High temperature services
What is reinforce concrete t-beam?
It is a monolythic concrete beam consisting of a web and a flange to form the shape of a"T" .
