Are Concrete Expansion Joints Necessary

importance of expansion joints in an architectural,concrete slabs, building faces, and pipelines contract and expand throughout the year because of the cooling and warming due to some heat resources and through seasonal variation. these joints can be used in paper, oil, and petrochemical industries and in various other fields. the variety of expansion joints present for application is wonderful..how often do you need expansion joints in concrete,how often do you need expansion joints? usually, expansion joints should be no farther apart than 2 to 3 times (in feet) the total width of the concrete (in inches). so for a 4 inch thick concrete slab, expansion joints should be no more than 8 to 12 feet apart. they should also be placed around structures that go deeper than the concrete slab, such as columns or walls. contact kaloutas..

    while for some pavements, conditions like temperature extremes may make closer spacing preferable, and/or make it necessary for a significantly wider expansion joint (the greater the temperature difference between extreme high and extreme low temperatures, the move expansion/contraction in the concrete will occur), or if wider joints are not desirable, the joints make be closer together.
