What is a raft foundation?
1. Excavation of the soil up to required depth.2. Ramming the foundation bed.3. Cutting the concrete over the reinforcement.4. Laying the reinforcement over the the foundation bed.5. Pouring the cement concrete over the reinforcement.
What is result of more reinforcements used in structure?
The structure is called a over reinforced concrete or structure. The structure can fail without warning. Discuss why managers she would always t ry to use positive reinforcement instead of negative reinforcement
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.
Can you pour a concrete sidewalk over top of another existing concrete sidewalk?
No do to the concrete settling the concrete on top would split
Can you install vinyl flooring over concrete?
If the concrete is indoors, dry, and in good shape, yes.
Which reinforcement is safe under or over reinforcement?
Under reinforcement is safe because in this case steel fails before concrete.

What do you mean by honeycomb in concrete?
Honeycomb is a defect in the hardened cement concrete consisting of many air pockets or voids due to which concrete deteriorates by entrapment of moisture that causes corrosion of reinforcement bars resulting in failure of structural members over a period of time if not rectified at the earliest.

How do you cover brick with concrete?
POUR THE CONCRETE OVER THE BRICK
Why iron metal is used in building construction?
It deals with the tension and compression of the concrete. Concrete is a really great material when in comes to compression. It has a high strength in compression but little in the way of tension. You can test this for your self. Get a small unreinforced piece of concrete and pull it apart it ( put it in tension) and it breaks fairy easily. Now, try pushing together (put it in compression) and it doesn't break anywhere near as easily, if you can break it at all. Steel is the opposite. It has more strength in tension than in compression. Putting steel bars in concrete allows you to have good strength in compression and in tension. In an easy way to understand it and get the general idea, when the reinforced concrete is under tension, the steel bars take over, and when the reinforced concrete is under compression, the concrete takes over.

Can you get a handprint off concrete?
pour more concrete over the top and smooth it out
Why is it easier to push a crate over a smooth concrete sidewalk than over grass?
There's less friction over a smooth concrete sidewalk

What is the difference Between under reinforced section and over reinforced section?
When the maximum stresses in steel and concrete simultaniously reaches allowable value the section is called balanced section when the %of steel in a section is less than that required for a balanced section it is under reinforced section when the %of steel in a section is more than that required for a balanced section it is over reinforced sectionover reinforcement is as per section design I.e Ast1+Ast2>Ast Ast1+Ast2
