nylon fibers absorbs water during mixing process.
therefore it is effective the water / cement ratio.
Wo do not recommend to use nylon fibers
however other fibers like polyfibers (polypropylene) have much better performance.
ýn you question, it is not clear that which purpose will you use fibers...

The answer is in the motor model.<br>
<br>
Why the stator takes 5 or 6 times more while starting?<br>
<br>
Because rotor's impedance equals zero in the begining and stator has short circuit current.<br>
<br>
If 100% full load exist, notting will change in electrical diagram, so current will...

Infact, all pigments are not for concrete. There are a lot of pigment existing.<br>
<br>
The correct pigment (not any dyes) is ironoxides.<br>
<br>
In short view:<br>
<br>
Ironoxides for red and yellow<br>
cobaltoxides for blue<br>
chromeoxides for green<br>
<br>
