With the weather the concrete can expand or contract and the gaps in the concrete are left to allow for this expansion of contraction so the concrete doesn't crack or break.

What are three examples were expansion is a nuisance and explain how the expansion is overcome are accommodated?
Can cause railways to bent. To prevent it,gaps are left along the line
What are the particles like in a rubber band?
the particles have large gaps in them
Define vibration of concrete and its importance?
Vibration is a process by which fully compacted concrete is achived.Importance:Prevents honeycombingPrevents segregation and bleeding of concreteExpuls air from concrete.
How much cubic meter of concrete will use for 1000sft slab?
m20 grade concrete per m3 load
Can concrete turn into a liquid?
no once the concrete gets hard it cannot turn into liquid state again but you can turn concrete powder into liquid by adding water :)
How do concrete gaps keep the concrete from cracking during the winter?
During winter when the concrete contracts/shrinks and there is no gap, then it will crack from the surface. So gaps are left in concrete such that it can shrink to a safe limit without cracking it.
Why do concrete roads have gaps between large pieces of concrete?
As the weather varies the concrete expands and contracts. If there were no gaps the concrete would buckle and crack.
Why do roads have the gaps between the large pieces of concrete?
They are expansion gaps that allow for the expansion and contraction of the concrete.
When temperature rises what will happen to the gaps between the concrete sections?
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
When the temperature rises what will happen to the gaps between the concrete sections?
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
Why concrete roads have gaps?
because it expands and contracts depending on the temperature..the gaps allow the concrete some space to expand so that it will not crack..
Why are concrete highways made in short sections with tar-filled gaps between them?
The tar gaps are where the hwy has been repaired.
Why concrete highways are made in short sections with tar-filled gaps between them?
The tar gaps are where the hwy has been repaired.
Why are there gaps in between sidewalks?
Concrete, like most materials, expands and contracts with the temperature. The gaps allow the surface to do so without cracking.
What are expansion gaps?
Expansion gaps are the controlled gaps between the structure. The gaps purpose is to compensate and go with the changes of the structure overtime.For example: Materials such as concrete shrink overtime and clay expand slowly. So, it is needed for the structure to have expansion gaps to avoid damages.
What eventually happened to the gaps left in the periodic table left by Mendeleev?
he knew that later on the gaps would eventually get filled up
What are the gaps in the concrete road made of and why is that material used?
There are several ways that the thermal expansion joints in a concrete road surface can be made:cut by a concrete saw after the concrete sets, there is no material in the jointfilled with a compressible fiberboard spacer before pouring the concrete, this spacer is left behind in the joint and easily compresses when the concrete expands and expands when the concrete contractsfilled with interleaved steel teeth before pouring the concrete, these teeth slide past each other as the concrete expands and contracts they provide a smoother road surface and are commonly used on bridgesetc.
