Can you use PVC pipe in concrete?

NO. you should never pour concrete on any pvc conduit or water pipes unless you wrap the pipes with a form wrap to allow expansion and contraction and any penetration thru the concrete or install a 4in or 6in sleeve under the slab to pass the pipes though.

What can be used for concrete reinforcement?

Steel is the most common material used as reinforcement, but other materials such as fiber-reinforced polymer (FRP) are also used. The reinforcement must be of the right kind, of the right amount, and in the right place in order for the concrete struc- ture to meet its requirements for strength and serviceability.

Can you use pipe for rebar?

If you need to bend a couple pieces of rebar for a small concrete pour, you could go rent an expensive rebar bender, but if you want to save a few extra bucks, there’s a better way. Jim Blodgett of Roy, Washington, figured out that he could bend rebar pretty easily with a pair of steel pipes.

How strong is PVC filled with concrete?

The average compressive strength results obtained from 150 mm cubes and 100×200 mm cylinders at 28-days of curing are 26.3 MPa and 21.6 MPa, respectively. The PVC tubes with thickness of 3.5 mm and a diameter of 100 mm were cut to the length of 700 mm as shown in Fig.

How do you bond PVC pipe to concrete?

The process involves applying primer to the outside of the pipe and the inside of the fitting, which cleans and preps the PVC. After about 10 seconds, you next apply cement to the same areas, then insert the pipe snugly into the fitting and allow the cement to set.

How can I make concrete stronger without rebar?

If you’re not doing a commercial-level project but still want some additional reinforcement for your concrete, a wire mesh is a great (and cheaper) alternative to rebar. Wire mesh use is becoming much more common for projects like a home driveway.

Does filling pipe with concrete make it stronger?

Thicker wall and bigger diameter put you in the right direction. The most popular suggestion here is filling the tube with concrete. This no doubt will get you a stronger member that is capable in flexing more and take more load without bucking the top or compression side of the tube.

Does PVC react with concrete?

A. According to Bernard Erlin, the principal chemicals in concrete that could conceivably attack plastics are calcium hydroxide, sodium hydroxide and potassium hydroxide. Erlin cites a table from Handbook of Chemistry and Physics stating that rigid PVC has excellent resistance to strong alkalies.
