Great information!
So frustrating trying to find local supplies... I'm in Northern KY,,, Cincinnati OH area... Too bad you don't sell at Deco-cretesupply here in Cincinnati... otherwise I bet shipping is crazy... Is your Trinic 10 the base for your GFRC Premix? If yes what would I need to add to it... White Portland which I can get locally... and a white sand?... I would need to search for the sand... this is why your premix is needed... sourcing from some locations is difficult... I don't make countertops... I mostly do casting and want high-performance castable GFRC concrete in white... I know I can cast using Cement all but I don't like it...
We do have a distributor in Bowling Green, KY - Jeff Osborne Design 112 Thomas Ct. Unit #C, Bowling Green, KY 42101 270-303-5818 jeff@jeffosbornedesign.com If you go on our website and use the GFRC Mix Design calculator you can see everything you'll need for a mix using Tec-10 - trinic.us/pages/calculators
Few things I would like to know... de-mold time for your castings... does this have CSA in it to speed de-mold times and strength for production casting? Is this a pure white color? ... any marble in it?... I know this is a 1yr old post but it will show me what type of company you are if you answer
We demold the next day (14-18 hours is fine ). We do have a fast-set version with CSA added. Those can be demolded in about 2 hours. We use Federal White cement so our mixes are white (not exactly pure white though) - no marble. We host free workshops ( just had one last week). If you'd like to be notified of upcoming classes, email us - Rich@trinic.us
PS dispersing fibers are very different from Bundled fibers. Dispersing fibers can help with micro cracking but do not add strength. Bundled fibers are for strength. Our GFRC premix with fiber added easily exceed 14,000psi in 28 days ( 7000+ next day).
Thanks Rich. I will check out your site
I have a GFRC question... For a case-in-place countertop, If I wanted to strengthen the mix with glass-fibers, but did not want the fibers to show on the surface, would it be a bad idea to pour the first 2/3 of the top with a mix containing fibers, THEN pour the upper 3rd with the same mix but with not fibers? ... I'm trying to achieve a 1" thick top. Thanks!
When would you want dispersing fiber as opposed to bundled fiber? What types of projects would require each kind and what are the best lengths?
Sorry for the late response... Please email our tech rep Nick@trinic.us - he can help you.
@@TrinicLLC Would have been nice to learn this here... instead of private
This is cool, I've done some test pours myself getting ready for a concrete countertop and am interested to know with scc cast in place if you can skip troweling sinc it looks so good already?
For cast in place, you'll want our GFRC premix without plasticizer, and it will need to be troweled. The SCC is pourable but the specific gravity of the fibers makes them float up in the matrix and will be visible on your surface. We us SCC in molds that will be flipped so the finish side in down during the casting process.
@@TrinicLLC Gotcha, yeah, discovered I had to trowel, but as long as I waited long enough it wasn't an issue. The edges have to be troweled or cracks will show and since it was firm enough troweling wasn't that difficult. I used a mix with plasticizer, but poured the last portion without fibers after waiting some time so the fibers wouldn'tfloat to the top. Now to try the real thing
Could I use a regular drywall texture hopper gun to spray the mix?
Sorry for the late response... You can, but they don't work as well as the ones made for this work. People make due with them though.
Why not use polypropylene fibers? The “calindered” ones.
polypropylene fiber is not alkali resistant
@@elliotte1981 I was told opposite, glass degrades in alkaline. This is why concrete fibres are polypropylene.
Also if they poke out of the surface they can be melted off with a flame whereas glass can be an issue.
I’ve used both and I much prefer using poly.
@@rollovaughan AR (Alkali Resistant) glass will not react with the concrete. When using glass always use AR glass. We apply fiberless face coats to ensure fibers don't show through - the fiber only goes in your back coat. PVA fibers can be used in areas where you're concerned about fibers showing - they're invisible to the naked eye. If you have more questions/concerns give us call or email Nick@trinic.us we're happy to help.
All this waiting, ice etc. how could one spray hundreds of molds in a day and build production processes?
The wait you are referring to is not long at all. We only need to wait to make sure the ice has melted. That time can be spent cleaning tools or prepping a mold. If no ice is used, then there is no slake time needed for our mix. If you want to turn molds faster, try our GFRC fast-set premix. With that product you can demold in less than 2 hours. I hope this helps answer your question.
The sound is very bad
But did you learn anything?
@@richdoud3297 Yeah thank you, but while watching sound is disturbing my ears, i just want to kindly warn you
@@World180degrees We welcome all feedback & really appreciate constructive feedback. Next video we'll try mic'ing up our instructors instead of a camera mounted mic. We're concrete guys making videos not video tech guys...
