FIBER STEEL.....

[1215]

COULD WE MIX THE FIBER STEEL TO THE CONCRETE CEMENT WITHOUT REINFORCEMENT OF STEEL FOR HIGH PRESURE IN THE WATER SUPPLY SYSTEM.
FOR EXAMPLE IF WE CONSTRUCT A RESERVOIR IN AN ELEVATION OF 80 METER FOR THE GRAVITATION SYSTEM OF WATER SUPPLY, WE COULD JUST USE THE FIBER STEEL?...

1215,

I would recommend against using steel fibers anywhere that concrete structure could be subjected to abrasion, impact or turbulence.

The steel fibers, once exposed to these forces, act much like the string on a cardboard envelope. The water will get under it and lift it out of the matrix, exposing more aggregate and fiber. You will have a cascading effect and a catastrophic failure of your system.

Reinforcing steel with the collar ties away from the flow of the water would be your best bet. Fibers only improve the shear/flexural strength of concrete in structures that are ‘statically’ loaded and not subjected to impact. Thus a parking deck, even though it receives transient loads could be a candidate for fiber reinforced concrete, a spillway of a dam would not.


Good luck and keep us posted

I am very grateful for your academic and professional answer, about fiber steel because I am now very clarified. I will keep it well for my further knowledge and to increase my weakest experience in the future.
Once more thank you so much, Happy Easter and all the best .
see you in another time...

Dearest friends...

I actualy would like to enter in contact with yourselves since 23 th March 2003 for some discussions. But unfortunately I couldn't because I was so busy and my internet-computer system was out of order.

But now here we go....

From the International Critical Tables, the viscosity of water at 20 deg C is 0.010 08 poises. How to find that value, if in undeveloped country like East Timor there are no Laboratory for this purposes, because I use to discuss with some of my colleagues that we have to know the correct tempertaure of water in Deg Celsius to find the correct viscosity of water in order to facilitate us for some calculation of Presure Head and other porpuses. Could furthermore you tell me the other purposes of water viscosity? For your attention I tank you very much and see you in next time............
