What is fiber impregnated concrete?
It's concrete with chopped-up fiberglass in it, which makes it stronger.
What is the effect of hydration on strength of a concrete?
Excess water (over hydration) causes weak concrete. The water in concrete is there to start a chemical process which results in the hardening process. The excess water is not used in the chemical process and results in a weakened concrete.
Why concrete is strong in compression and weak in tension?
Concrete is strong in compression, as the aggregate efficiently carries the compression load. However, it is weak in tension as the cement holding the aggregate in place can crack, allowing the structure to fail. Reinforced concrete solves these problems by adding metal reinforcing bars, glass fiber, or plastic fiber to carry tensile loads
What are stress cuts in a concrete pad?
stress cuts also known as relief cuts make weak points in a concrete slab to allow for expansion and shrinkage cracks. Bascially, a concrete slab is going to crack and these cracks control where those cracks occur.
What can you reinforce concrete with?
There are different forces on a materials such as Compression and Tension. Compression is pushing a material together. Tension is pulling a material apart. Concrete has good strength in Compression, but is weak in Tension. The steel reinforcement improves the resistance to tension of the concrete.
Does low aggregate demand make the economy weak?
what makes the economy weak
What makes Superman weak?
kryptonite
What is fiber impregnated concrete?

What is meant by reinforced concrete?
A reinforced concrete is a one in which steel is used. The inclusion of steel in concrete is to take up the tensile forces, since concrete is weak in tension and strong in compression. Moreover it gives warning of the structure before failure.
What is the effect of hydration on strength of a concrete?
Excess water (over hydration) causes weak concrete. The water in concrete is there to start a chemical process which results in the hardening process. The excess water is not used in the chemical process and results in a weakened concrete.
Why is the steam of aquatic plants weak?
Vascular tissue is the tissue which makes steam strong . As their are no such tissue in steam of aquatic plant it makes them weak.
What makes a weak bone?
no calcium no calcium
Why are there cracks on concrete paths?
Concrete has great compressional strength but very weak torque resistance. That means when the ground underneath concrete paths settles or erodes the concrete will crack. In order to determine where the concrete will crack the constructors leave faults in it. So when the concrete does crack it does so in such a manner that the path is still functional and aesthetic.
What makes a sound loud or soft?
Damping makes a sound weak and amplifying makes it strong.
What is the purpose of using metal bars or mesh in the construction of concrete roads?
Concrete, while strong under compressive forces is very weak under stretching forces. Metal bars or mesh, while strong under stretching forces is very weak under compressive forces. Thus they compliment and mutually reinforce each other: where one is weak the other is strong.To make sure they are both able to work their best, the metal bars or mesh are first stretched then the concrete is pored over them. When the concrete completes setting the metal bars or mesh are released and they now compress the concrete while the concrete keeps them stretched. This is called prestressed concreteand it is much stronger than ordinary concrete.
Why are recycled bag weak?
The raw materials from which they are made contain impurities, which makes the bags weak.
What is reinforced concrete?
Reinforced concrete is concrete reinforced with steel bars because although concrete is very strong in compression (depending on its components) it is very weak in tension and the steel bars make up for the required tensile strength.
