What else can I help you with?
Does concrete expand?
yes, that is why they put expansion joints on bridges. (: your welcomeyes, that is why they put expansion joints on bridges. (: your welcome
What is the control joints?
Control joints (often confused with expansion joints) are cut into the concrete or asphalt, and are different from expansion joints as shown in the photo. The joints are cut into the structure at regular intervals allow cracking to occur in a controlled fashion. Road control joints can be sealed with hot tar, cold sealant (such as silicone), or compression sealant (such as rubber).
What might happen on a hot day if expansion joints were not used?
On a hot day, materials like concrete and metal expand due to increased temperatures. Without expansion joints, this expansion can lead to significant stress and pressure within structures, causing cracks, buckling, or even structural failure. Additionally, the lack of expansion joints can hinder the movement of materials, resulting in misalignment and compromised integrity over time. Overall, the absence of these joints can lead to costly repairs and safety hazards.
Why should large concrete slabs be laid with expansion so that they are not touching?
because large slabs of concrete have expansion joints between them.
How do expansion joints in a sidewalk keep the concrete from cracking?
The expansion joint in a sidewalk keeps the concrete from cracking just as what its called. It allows the concrete to expand when heated and contract when cold. Without the joint, the concrete will crack and become uneven or mountain up.

What is the general cost for replacing the sealant and backer rod on expansion joints?
what is the general cost for sealant replacing in expansion joints
Expansion Joints?
Expansion Joints are installed in the piping system to absorb vibration and shock. They also have the Advantage of reducing noise and compensating caused by misalignment.
What happens to a bridge's expansion joints on a hot day?
If there is no expansion joints on a bridge and if it's really hot the molecules of the bridge will be separated slowly and the bridge will collapse
Why are there joints in bridges?
The space at the joints is there to allow for expansion and contraction of the length of the bridge depending on the temperature.
What is the control joints?
Control joints (often confused with expansion joints) are cut into the concrete or asphalt, and are different from expansion joints as shown in the photo. The joints are cut into the structure at regular intervals allow cracking to occur in a controlled fashion. Road control joints can be sealed with hot tar, cold sealant (such as silicone), or compression sealant (such as rubber).
Where i use the expansion joint?
For sidewalk code is generally every 30 ft. For a masonry wall it is also every 30 ft. Place celotex every 30 feet on a sidewalk and this will eliminate buckling of the slab. www.masonryworktools.com
What is the maximum size a concrete slab can be without the need for expansion joints?
The maximum size for a concrete slab without needing expansion joints is typically around 100 to 150 feet in either direction. Beyond this size, expansion joints are usually necessary to prevent cracking due to temperature changes and shrinkage.
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.
What is the control?
Control joints (often confused with expansion joints) are cut into the concrete or asphalt, and are different from expansion joints as shown in the photo. The joints are cut into the structure at regular intervals allow cracking to occur in a controlled fashion. Road control joints can be sealed with hot tar, cold sealant (such as silicone), or compression sealant (such as rubber).
Hangers used when thermal horizontal movement is a factor with piping?
Expansion joints are typically used when thermal horizontal movement is a factor with piping. They allow for movement in the horizontal direction to accommodate thermal expansion without putting stress on the piping system. These expansion joints can come in various forms such as bellows or slip joints.
How did canals and new roads affect the westward expansion of the US?
the canals and the new roads affect the westward expansion because more people came to the west and was trading and bringing goods.
