Is it safe to cut the post tension concrete slab foundation to fine sewer line for bathroom addition?
No, You must first locate the P.T cables, and because you said it is to find a sewer line im guessing this is slab-on-grade and not a deck. The only method for locating post tension cables on slab-on-grade is with Ground Penetrating Radar. If its on a deck you can use Ground Penetrating Radar or Xray. If you cut a P.T. cable you can weaken the structure and cause damage. P.T cables are known to shoot out of the side of a building when cut. And repairing the broken cable is extremely costly.

Why use rebar in concrete?
Concrete is good in compression, poor in tension. Steel is good in tension, poor in tension. By the addition of reinforcing steel into concrete, you take the strengths of one material and marry it to the weakness of the other. This provides a better product capable of better performance in the field.
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.
Why do engineers use reinforced concrete?
Concrete is a material which is extremely effective when loaded in compression, yet performs poorly when loaded in tension. Steel on the other hand is quite effective in tension. Reinforced concrete uses steel bars wherever the concrete is loaded in tension in order to increase its capacity.
How do you use the word tension in a sentence?
The tension in the room was palpable as the two rivals faced off.
What is the difference between reinforced concrete and pre stressed concrete?
Reinforced concrete has reinforcing bars (called rebar) simply embedded in the pour. With prestressed concrete, reinforcing rods or cables are stretched (stressed) and then the concrete is poured around them. After the concrete hardens, the tension on the reinforcing members compresses the concrete, making it more resistant to failure where poor soil conditions or severe loads exist.Prestressed construction is usually done in-plant because of the equipment involved, and the completed assembly shipped to the site for installation.A similar method, called post-tension, is usually done on site, and involves the tensioning of reinforcing cables after the slab is poured, using a special hydraulic jack.
What are the benefits of using a curved shower rod tension in a bathroom?
A curved shower rod tension in a bathroom provides more space inside the shower, reduces water splashing outside the shower, and adds a stylish touch to the bathroom decor.

What is Reinforced cement concrete-RCC?
Concrete is very strong in compression but weak in tension. RCC is concrete with reinforcing steel bars in it. Steel is a really good material in tension. Steel carries the tensile load and thus RCC is strong in tension too. However, designers still try to ensure concrete is in compression wherever possible.
What do poured concrete cages do?
They for strength for concrete structures. Concrete, like masonry, is strong in compression (forces downward on it) but not in tension (stretched out). Therefore the steel gives the concrete tensile strength.
What is important of steel in the rienforced concrete?
Concrete is basically strong in compression butWEAK IN TENSION this limitation can be compensated by providing steel as being strong in tension it takes the tensile forces and make section safe in tension.......moreover both concrete and steel have same coefficient for thermal expansion so there are no additional stresses due to temperature change.
How is Reinforced concrete made?
Reinforced concrete is made by placing steel bars in the tension zone of the beam x-section.
Why steel is used to reinforce concrete explain it?
There are two main loading conditions that concrete under goes. These are Compression and Tension. Concrete is very strong in compression and is very weak in Tension (pulling apart). Concrete has so little strength to resist tension it is assumed to have no strength in tension. When civil engineers design concrete structures they can determine where the tension and compression will be located. Steel is added to give the concrete tensile strength. For Example a concrete beam when loaded from the top will experience compression on top section of the beam. The top portion of the beam will push inwards creating compression while the bottom section will pull apart creating tension. (Imagine a smile shape). :) Therefore reinforcement will be needed in the tension area (bottom).
