Plastic fittings for the foundation

Good afternoon! We bought colored reinforcement of the Taganrog manufacturer with a diameter of 12 mm in the Bau-center. as it turned out, they dye it to hide the marriage, when unwinding, the reinforcement bar broke badly to think what would happen to it in concrete, they began to measure it and it was 10 at best. , we didn’t respond intelligently to our request to the manufacturer’s company about the correct measurement and compliance with GOST, and moreover, we were also rude. So it turns out that some scammers produce and sell it. Beware of the Taganrog plant.

NOT IDENTIFIED - A big risk in our case is to use it in construction. Perhaps other manufacturers with quality are doing well!

Unsuitable for construction, painted to hide the marriage. Does not match the diameter sold.

Plastic (in particular fiberglass) reinforcement has a tensile strength 3 times greater than metal (1.5 times stronger than a special high-strength alloy) so at a price compare metal D12 and fiberglass D4 !!! the thermal expansion of fiberglass is the same as that of ubetone, the metal is slightly different! There are also disadvantages: it bends badly, low shear strength. It is advisable to knit a mesh from composite reinforcement more often using thinner reinforcement, as adhesion to concrete is weak. The main drawback is QUALITY !!! For many manufacturers, to put it mildly, not very.

Stronger than metal
when recounting cheaper.
Convenient in delivery and installation.
It has the same coefficient of thermal expansion as concrete.

unknown QUALITY from non-certified manufacturers.
Low shear strength.

We used fiberglass reinforcement with a diameter of 10 mm to create the base when pouring a concave basin of the pool and during the formation of arched walls. With metal, one would have to sweat pretty hard by bending the rods at different angles or by welding together reinforcement cut into small segments into a large spatial structure. When installing fiberglass reinforcement special problems with this did not arise. In addition, the speed of attachment to plastic ties was also impressive. The only tangible drawback is the need to fill reinforcement overlays in the bearing plates only with preliminary tension (equipment rental is quite expensive).And the price of the product itself is very high, which does not allow it to be used much wider in areas where its use would be very helpful due to its unique technical characteristics.

Fiberglass reinforcement has excellent performance characteristics that we use for its non-traditional applications. First of all, these are stiffeners for portable hotbeds. This year, swung at a full greenhouse. At the same time, the ends of the fittings do not need to be additionally protected, they simply stick into the ground. It is because of the complete immunity to humidity that fiberglass reinforcement is so convenient to use in landscape design as an element of garden structures and small architectural forms. For example, we have all frames for climbing plants and retaining walls made of this material. In addition, the long shaft copes well when cleaning the pipes of the sewage system and stormwater.

I am the owner of a small company for the construction of private houses, so I deal with various building materials and their use. I can confidently state that the use of fiberglass reinforcement is not yet economically feasible. The cost of D12 fittings in retail comes out to 25 r linear meter, and for bulk purchases it is even cheaper - up to 20. And compare this with fiberglass - akcsibir sells its products. At 41 p for 1 running at retail and 35 p. / M p. Wholesale. And you don’t need to tell tales that fiberglass is cheaper and therefore there is more in a ton, it’s just a marketing move by sellers, do not be fooled. The fittings are bought anyway by running meters, just as they are used. The only advantage is light weight, but it is also useless, since the use of fiberglass reinforcement is strictly prohibited for floor slabs.

Many of the technical indicators of fiberglass reinforcement are clearly redundant, and some are insufficient, especially in private construction. Well, for example, why do I need acid resistance. I have a residential building. Not a repository of chemical waste. Not electrically conductive - well, I don’t even know why this indicator was written as a plus to her. I’ll open a big secret: when pouring the foundation in winter, it is the connection of the reinforcing cage to electricity that turns it into a heating element that helps harden concrete. Well, I don’t even want to comment on the properties of inertness to magnetic fields and permeability to radio waves and cellular waves. I’ll just add that for private construction, to make the wall impervious to the mobile phone, it needs to be 50% of the reinforcement. And this is not to mention the low ultimate tensile strength.

All key indicators are clearly redundant

In general, purely for money goes as follows. Fiberglass reinforcement 10 mm thick is approximately the same as metal ASP-10 and 10A-III. I think it’s not worth saying which fill will be stronger. In addition, when choosing fiberglass reinforcement, you should pay attention to the following important details:

The rate of thermal expansion. Steel has about the same as concrete, fiberglass does not. Therefore, during heating and cooling, extraneous sounds will appear, and with intense temperature exposure, peeling can also occur.

In addition, do not forget about the combustibility of the material.
Plasticity and flexibility of steel reinforcement combined with its strength make this building material so popular in concreting. When struck, the plastic reinforcement is simply cut off, and the metal will stand.
