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.
Buckling; shriveling, bending, or curling from heating or pressure. (heating, in this case)
Construction joints are typically made using materials such as concrete, steel, and various sealants. Concrete serves as the primary material for structural integrity, while steel reinforcements can be used to enhance strength and durability. Sealants are applied to prevent water infiltration and accommodate thermal expansion or contraction. Additionally, materials like rubber or plastic may be used for expansion joints to allow movement without compromising structural integrity.
they're both used for the same purpose i.e. fill joints and cracks between building materials. They're also both applied with a caulking gun. sealant is used when there will be expansion and contraction and thermal changes. caulk is recommended in a opposite scenario where expansion and contraction are not an issue because caulk will eventually dry and crack if there's movement. caulk can be painted, sealant cannot.

It is not a must. Plenty of builders out there not using steel. The steel, when run thru your expansion joints will keep the sections from shifting and add strength to the concrete. Wire mesh is a waste of time and money.
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.
Expansion joints are used in parking garages to abosrb the heat and contraction movement of the parking garage. During seasonal changes garages can move and fail under the weight of hundreds of cars.
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

Expansion joints are used on long runs (over 100 feet) of pipe or ducts where the expansion of steel will create stress on the pipe or its supports. for every 1 degree change in metal temperature the pipe will expand 6 millionths of a foot per foot of length. on a steam pipe 400 foot long carrying 750 degree steam this expansion would amount to a change in length of the pipe of 1.632 feet. this could tear down the supporting structure if this expansion weren't relieved by an expansion joint every 100 feet. expansion joints could be flexible corrugated pipe, reinforced rubber sheet, sliding pipe joints, or expansion loops, among other things.
An expansion joint is used in construction to help deal with the effects of building materials expanding and contracting. They can be purchased through hardware stores like Home Depot.

Expansion joints include: PTFE expansion joint, Rubber expansion joint, Metallic expansion joint, and Fabric expansion joint. visit website: www.rubbersealing.comPTFE expansion jointThe PTFE expansion joints are unreinforced PTFE that come standard with iron 150# drill flanges. Stainless flanges are available. They are avaialable in 2, 3, or 5convolutions of varing movements. The 2-convolution joint is sometimes referred to as a "coupling".Molded flexible couplings and expansion joints of PTFEdesigned to help protect pumps, compressors and other expensive equipment.Bellows-type flexible couplings and expansion joints are contour molded of black PTFE by a patented process. They are corrosion resistant, non-aging, with extraordinary flex life and unmatched reliability. These superior units cost no more than those made of lesser materials. The flexible element is formed over the full sealing face of the end flanges eliminating troublesome separate gaskets.Note the change in pressure rating with

Woodwork joints are a series of joints used for woodwork.
An Expansion Joint ( Bellows ) is used in the piping system to absorb thermal expansion or terminal movement, where the use of an expansion loop is impractical. Expansion joints are in different shapes and materials. Expansion joints are rubber, metallic, Teflon joints
