Best answer

An expansion joint is designed to absorb safely the expansion and contraction of several construction materials, absorb vibrations, and permit soil movements due to earthquakes or ground settlement. The expansion joints are normally located between sections of bridges, paving slabs, railway tracks, and piping systems.

Which bridge is stronger concrete or steel?

Asked By: Don McCurdy Date created: Jun 23, 2022

There is no statistical evidence to support that concrete is better than steel. In fact, it has been shown that concrete cracks and has a lower tensile strength than other materials. Conversely, steel does not crack and often sees wear and tear at the joints and bearings, an easy enough fix for construction teams.

What do you put between concrete and House?

Asked By: Paul Ogilvie Date created: Jun 10, 2022

Water can get into the joints, freeze and then expand, making the cracks even larger. Gaps against a house can direct water against the foundation, leading to more problems. Once a year, go around your home and fill these gaps and joints with urethane caulk (or polyurethane caulk) to prevent problems.

What are the causes of concrete failure?

Asked By: Kherel Date created: Jun 14, 2022

The two most common causes of failure are carbonation and chloride contamination of the concrete. Both of these lead to corrosion of the embedded steel reinforcement and as the steel corrodes it expands and exerts pressure on the concrete so that, eventually, the concrete cracks and spalls.

Do I need rebar for small concrete slab?

Asked By: Axeman Date created: Jun 08, 2022

You do not need rebar for any slab if you make it thick enough and space the joints properly. Rebar in jointed pavement is there to counter the cupping effect of thermal expansion. I always recommend the use of rebar or at least rewire. Any concrete slab can crack.

Are concrete expansion joints necessary?

Asked By: daouzli Date created: Jun 18, 2022

Expansion joints are virtually never needed with interior slabs, because the concrete doesn't expand that much—it never gets that hot. Expansion joints in concrete pavement are also seldom needed, since the contraction joints open enough (from drying shrinkage) to account for temperature expansion.
