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.
What is the day and night temperature for mercury?
Bloody hot in the day and hot at night
Does a glass tumbler containing hot water crack if you cool it by pouring cold water on it?
Yes, it is possible for a glass tumbler containing hot water to crack if you cool it rapidly by pouring cold water on it. The sudden change in temperature can create stress within the glass, causing it to crack or shatter. It is recommended to gradually cool the glass to prevent this from happening.
Is the word scorch a concrete noun?
Scorch is a verb, meaning to burn something. Be careful not to scorch the blouse with the hot iron.
Why do wet clothes on a washing line dry faster on a hot day than a cold day?
Because on got day there is less moisture in air so, the clothes dry faster on a hot day than a cool day.
How does hot weather make concrete crack?
If the correct concrete mix is used and laid properly, hot weather should not make concrete crack. Instead, it is the freeze-thaw cycle that makes concrete crack.
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
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.
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.
If a concrete bridge is exposed to sunlight on a very hot day would it expand or contract?
The concrete bridge would expand when exposed to sunlight on a very hot day due to the heat causing the material to increase in size. As the concrete absorbs heat, the molecules within the material move faster and take up more space, leading to expansion.
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.
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.
What three groups can be animals be divided into based on how they get energy?
