3 reasons to abandon the reinforcement of composite reinforcement

On the application of composite reinforcement I gave up after this material had to work on two sites. Then strongly urged customers to use metal. And that's why.

From what and how to make a composite reinforcement?

Depending on the fibers used in the manufacture of fittings can be steklokompozitnoy, carbon composite, aramidokompozitnoy, bazaltokompozitnoy or combined. When you ask managers what they sell, answer two: fiberglass or composite. Look in the documents, it is not always fiberglass.

The problem is not even the fact that the manager is "wrong." Different types of valves different characteristics! We are all presented as one and the same material. Choose only offer diameter.

I'm no expert in fiberglass reinforcement, but even the appearance of the material with which to work, in doubt. Uneven winding profile, the shade smoothly flowing from light yellow to dark brown and back. Only one conclusion - kosyachat manufacturers of raw materials and processing technology. When he began to be interested in how this prodigy do, everything fell into place.

For the production of composite reinforcement is not necessary to build a huge factory and assemble a team of highly qualified staff. Quite a few machines, large "garage" and Uncle Bob (caretaker) as the operator. Trust your house like the experts, I would not venture.

How to work with composite reinforcement?

The first question that I came across on the subject: how to make the bent element from this material? At the construction site to bend it will not work. In theory, under the order such details can make the manufacturer. But in practice, to reach the "factory" and failed.

Zaarmirovat critical structures whips straight in practice impossible. Need clamps, T- and U-shaped elements. We can not abandon them. Why, I partially answered in the article about critical error reinforcing angles strip foundation.

Design characteristics of composite reinforcement - a myth?

Managers like to compare the fiberglass with steel reinforcement strength: four instead of six, eight instead of twelve. Yes, get some of the composite on a laboratory bench possible. But the fittings - it is a structural member. Wrong to consider it separately from the concrete.

There is a method for calculating wood, steel, concrete, IRON(!)concrete structures. I believe that blindly apply all the formulas for calculation of reinforced concrete on the fiberglass too presumptuous. As long as there is no sufficient regulatory framework on the use of this material, I'll pass.

On this I have everything. Thank you for reading! If the article was helpful subscribe to the channel. Best thanks - your 👍 Like and repost.
