What happens if concrete is exposed to water?

What happens if concrete is exposed to water? When excess water creates greater spaces between aggregate materials, the voids fill with air after the moisture evaporates. The resulting inadequate compaction reduces the concrete’s strength. … Water containing bicarbonate ions and carbon dioxide causes a reaction known as carbonation in concrete.

Can concrete be damaged by water? Concrete slabs are very porous. This means standing water can easily fill in pores on the surface and eventually break down the concrete. As a result, the concrete may crack, move, or even settle.

Why concrete roads are noisier than asphalt?

Concrete can also be very loud because the rigid pavement doesn’t absorb sound. … This pavement is flexible because it bends or deflects the weight of vehicles that drive over it. Along with reducing sound, absorbent asphalt provides drainage and decreases the amount of standing water on any given road.
