Cracks in the cement are cause by a mechanical change due to weathering. when it ices and snows, it puts stress on the cement and causes a change.
Also various reasons r thr..... adding excessive amount of water, or less water or if water evaporates faster than it is poured, else if thr r high temperatures, if thr r elements or components which will corrrode, it might crack.....

Can concrete be melted by lava?
It might be possible to melt concrete if lava in contact with it was hot enough. But it is more likely that concrete would decompose and become "crumbly" before it "melted" when heated.

Does concrete expand on hot days?
A little bit, but not much. If it is really hot, and then really cold, then your cement will crack.
Why do concrete patios crack?
A concrete patio usually cracks due to heat cold. If it is to cold it contract and break. If it is to hot it will expand and break. Then water can seep into those cracks and freeze causing the crack to expand
Name a place you would not like to be on a hot day?
city roads
Why would it be a bad idea to reinforce concrete with aluminum rods?
They do not expand equally, therefore the aluminium might crack the concrete on a hot day (or vice versa) due to this difference in expansion. i.e steel rods can be used to reinforce concrete because both materials expand equally.
At the end of each winter roads are usually filled with cracks and potholes Why do you think this happens after cold winter rather than a hot summer?
In the winter the roads crack because the cold causes the concrete to contract, therefore making cracks and potholes in the road. This will not happen in the summer because the heat makes the concrete expand.
What is an expansion joint in construction?
An "expansion joint" is a joint left in between sections of the same material, like concrete or steel, that allows movement as the material heats up or cools down. Without it, concrete, for example, can expand and crack in hot temperature.
How soon after pouring can you walk on concrete?
Usually 24 hours, depending on temperature and humidity. If it is excessively hot, you could walk on it sooner, and if it is cold or damp, you might want to give it a little longer. If it is hot, you might want to consider covering the concrete with plastic a couple of hours after finish, so that the moisture will not excape too rapidly, causing the concrete to shrink and crack. If you are going to put a lot of weight on the concrete, such as a car, wait at least a week, to be safe.
How hot can concrete get?
Concrete can reach temperatures of up to 572 degrees Fahrenheit (300 degrees Celsius) before it begins to lose its structural integrity and strength. After this point, it may start to crack, spall, or experience other detrimental effects.
