Can concrete shrink after it is cured?
Once the moisture is out of the concrete and it is cured it should not shrink - it is however in a state of stress so make sure control joints are added to any large concrete areas that are poured and placed.
Will placing a magnet on concrete damage it?
I don't have an answer but we have several large magnets in the shop I work in. It would appear that when we lower the cranes down and place the magnets directly on the concrete floor it tends to weaken them. I have always heard that placing a car battery on concrete would weaken the battery . Does a magnet act in the same fashion?
Why do concrete roads have gaps between large pieces of concrete?
As the weather varies the concrete expands and contracts. If there were no gaps the concrete would buckle and crack.
What is the advantages of using plum concrete?

What is the applications of prestressed concrete?
Applications of prestressed concrete:Used in large diameter concrete pipesUsed in railway sleepersWater tanksPrecast concrete piles to counter tensile stress during transport and erection. used in bridges construction
Why do roads have the gaps between the large pieces of concrete?

The best method for repairing a large concrete crack using a concrete filler is to clean the crack thoroughly, apply the filler according to the manufacturer's instructions, and allow it to cure completely before sealing the surface.
How might the expansion of water when it freezes explain the cracking of concrete and pothole formation?
Because as a liquid, the water will run into small cracks on concrete or a road surface. When this water freezes it will expand and exert large forces on the sides of the crack, forcing it apart. This freezing and unfreezing cycle may continue several times, causing weaknesses in roads and concrete to break apart over time.
Why underestimate the resistance of concrete to such a large extent when you design concrete columns?
The designers calculate the potential effects of cracking on the concrete columns.
What is the best method for repairing a large concrete crack using a large concrete crack filler?
The best method for repairing a large concrete crack using a large concrete crack filler is to first clean the crack thoroughly, then apply the filler according to the manufacturer's instructions. Make sure to fill the crack completely and allow it to dry properly before using the repaired area.
What is dry lean concrete?
