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 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.
Why do roads have expansion joints?
so they can prevent it from breaking
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).

Why are there gaps at regular spots in the side walk?
They're called "expansion joints". Concrete expands and contracts with temperature changes. The expansion joints allow this to happen without cracking the concrete slab.
What are the two types of joints in construction?
Expansion joints. Butt,lap,half-housed,mortise/tenon and mitre joints to name some common ones.
Where i use the expansion joint?
Expansion joints are used in various types of structures and systems to accommodate the movement caused by thermal expansion, contraction, vibrations, settlement, or other dynamic forces. They are designed to prevent damage to the structure by allowing controlled movement while maintaining the structural integrity. Here are some common applications where expansion joints are used: **Buildings and Structures**: **Buildings**: Expansion joints are used in buildings to accommodate the movement caused by temperature changes and structural settling. They are often found in floors, walls, ceilings, and facades. **Bridges**: Expansion joints are critical in bridges to allow for the movement of the bridge components due to temperature fluctuations, traffic loads, and seismic activity. **Roads and Highways**: Expansion joints are used in roadways and highways to prevent cracking and damage due to thermal expansion and contraction. They also accommodate the movement caused by heavy traffic loads. **Piping Systems**: **Industrial Pipelines**: Expansion joints are installed in piping systems to absorb thermal expansion and contraction of pipes caused by temperature changes in the fluid being transported. **HVAC Systems**: In heating, ventilation, and air conditioning systems, expansion joints help compensate for the expansion and contraction of ductwork due to temperature changes. **Railways and Transit Systems**: **Railway Tracks**: Expansion joints are used in railway tracks to allow the rails to expand and contract with temperature changes. This helps prevent buckling and warping of the tracks. **Subway and Light Rail Systems**: Expansion joints are used in tunnels and station structures to accommodate the movement caused by ground settlement and vibrations. **Water and Wastewater Systems**: **Water Treatment Plants**: Expansion joints are used in water and wastewater treatment facilities to handle the movement of pipes and structures due to changes in water pressure, temperature, and ground settlement. **Aerospace and Transportation**: **Aircraft**: Expansion joints are used in aircraft components to accommodate the movement caused by changes in air pressure and temperature during flight. **Automobiles**: Expansion joints are found in exhaust systems and other components to absorb vibrations and thermal expansion. **Industrial Facilities**: **Manufacturing Plants**: Expansion joints are used in industrial facilities to allow for the movement of equipment, machinery, and structures due to temperature changes and vibrations. **Power Plants**: Expansion joints are used in power plants to handle the movement of pipes, boilers, and other components caused by temperature changes and pressure differentials. **Marine Structures**: **Harbors and Ports**: Expansion joints are used in dock structures and seawalls to accommodate tidal fluctuations and other dynamic forces. **Shipbuilding**: Expansion joints are used in shipbuilding to accommodate movement in the hull and other components. These are just a few examples of the many applications of expansion joints. The specific type of expansion joint used will depend on the requirements of the structure or system, the type of movement expected, and other factors. Proper design, installation, and maintenance of expansion joints are essential to ensure the longevity and functionality of the structure or system.
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.
