concrete absorbs, and then emits heat more efficiently than many natural materials. this is most easily evident when the sun just sets. for example, walk past a concrete wall/building that faces west just after the sun sets, you can quite easily feel heat being emitted from the concrete. (just like rocks in nature, really.) if you touch a tree just next to/near the wall you will feel it is comparatively quite cold. this is all pretty much common sense. but it effects the temperature measurements quite immensely.
many places where temperature was measured many years ago were urban areas. (for example, london in the 1800s. back then there werent as many buildings/concrete/roads etc...) now, if you measure the temp at the same place today, the temp is greater, due to the 'concrete jungle effect'. obviously, comparing these two measurements is void, as the environment in which the measurement has been taken is drastically different. yet advocates of climate change dont really acknowledge this as anything major (pretty stupidly). a better measure of the temperature of the earth is measuring temperatures either in rural areas, or at sea. if you do look at these measurements, the earths temperature appears either stable, or slightly cooling.
the concrete jungle has little effect on the actually temperature of the earth. it only effects the measurements we make. and it effects the measurements quite a large amount
What else can I help you with?
When concrete hardens it gives off thermal energy does the concretes temperature change?
Yes, when concrete hardens it undergoes an exothermic process which means it releases heat. This release of thermal energy can cause the temperature of the concrete to increase during the hardening process.
What is an example of a jungle?

Will concrete brick aluminum or copper take most energy to increase its temperature?
Copper will take the most energy to increase its temperature, followed by aluminum and then concrete brick. This is because copper has a higher specific heat capacity compared to aluminum and concrete brick, meaning it requires more energy to raise its temperature.
How do you increase slump in concrete?
If you are using a traditional concrete mix you can increase the slump by increasing the water you add.
How to improve the workability of concrete?
To improve the workability of concrete, issue to be concerned of as below: - increase water/cement ratio - increase size of aggregate - use well-rounded and smooth aggregate instead of irregular shape - increase the mixing time - increase the mixing temperature - use non-porous and saturated aggregate - with addition of air-entraining mixtures
What is the setting time of concrete?
The length of time that concrete takes to set, will depend on the temperature. It would take approximately 4 hours for concrete to set at a temperature of 80 degrees.
High temperature concrete?
80
Why does temperature vary with height?
As temperature increase pressure will increase
When the temperature rises on concrete and there are no gaps what happens?
When the temperature rises on concrete without any gaps, the concrete expands. This expansion can cause stress within the concrete structure, leading to potential cracks or damage if the temperature change is significant. The lack of gaps restricts the concrete's ability to expand freely, which can result in structural issues over time.
How does nano concrete differ from ordinary concrete?
Micro structure of concrete with nano materials gets changed like anything and is resulting tremendous increase in compressive strength apart from increase in specific surface area.
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.
What compound increase in solubility as temperature increase?
The vast majority of compounds increase in solubility as the temperature increases.
