I posted a video where I answered many of your questions about the Phoenix. You can find it here: kzfaq.info/get/bejne/Z7p2nZVj1NjZYas.html

Great speaking with you and Jake today. Looking forward to the next one! Shari9ng this video as I write this!

I love every time I see a new vid! Keep it up Professor Ley!!

We used to use a microwave to cook down concrete samples for this testing during main line paving. Is that not an acceptable test method for w/c ratio any longer?

Amazing channel and very informative content for any level of expertise!

Thank you for your exciting videos!

Very Nice presentation sir.....

Tyler, is the Pheonix capable of differentiating between the water in the mix versus things like liquid color or liquid admixtures? I assume this can be done by entering the specific gravities of these colors and/or admixtures?

Thank you very much professor, it's very useful video

Cool stuff!

awesome video as always tyler. question pertaining to natural pozzolans: because of their high water demand, what is batched as a 0.45 mixture with say 25% class n may perform like a much lower w/cm mixture after mixing. i venture to say there is an “effective w/cm” that is different than that of what was originally batched. would the phoenix test capture something like this?

This is a great idea!

Hi tyler, i saw few moths ago a video of you explainig about a material used as an addmixture called buarin or somthing like that, can you please send a link

FANTASTIC

I’d luv to see your view on the concrete at the SpaceX Boca Chica launch pad

How can i get ahold of u like a dm?

Isnt it better to check if water content is right with a microwave probe inside the concrete mixer? Even thou you can place aditional probe on the conveyor belt. To measure water content inside the aggregat.

Tyler, would you please do a video on this dry pour fad I keep seeing in my feed. It seems like a bad idea but I don't have any technical understanding to justify why I think its a bad idea.

This seems to be a water to stuff measuring system by using a very expensive, very fast, hot oven. Since the actual mix vs the batch ticket depends on the variability over time of the batching hardware (whether at plant or inside of a volumetric mixer), what has been the measured variability of these things across manufacturers and operators? It seems that if an operator can achieve a given measured calibration with minimum variation over time (of all the bits going in), the benefit of this device is to allow the operator to tweak a batch calibration for the actual water content of the aggregates coming from given piles on given days. With barrel mixers I definitely appreciate the value of this device to catch sloppy operators before it gets expensive for everybody.

How would plastic fibers affect the Phoenix?

What ASTM does this fall under? Thank you.

A newbie question, if the concrete has a slightly higher water content, wont it evaporate off as the concrete dries, but allow it to be well hydrated for good strength? Previous videos have shown its good to keep the concrete hydrated (watered often) during curing...

What about altitude. Doesnt that affect the time it takes for the water to evaporate?

This is really useful …

Hi professor, Yeah I think this is a game changer, but I assume I couldn't bought for my University's lab but just for testing the idea, how much heat does the oven should have? If you could reffer to a paper I'll apreciate, grettings from Bolivia

Only water and only cement has nothing to do with strength but it deals with consistency. For strength the cement paste should be good that's why gel space ratio is more important than w/c ratio but it has some drawbacks . It can prove more better results if some studies will be done on countering the drawbacks.

Hello Professor 👋

Interesting. Any connection to ASHTRICH LLC or Super Air Meter LLC?

I will be part of the Phoenix.

Can I rent one these machines from home depot?

What it needs to demonstrate is correlation between Phoenix numbers and Strength - 👍 Then there's value

Did you also test the diagnostic power by deliberately making faulty batches and seeing if the measurement properly reports the a priori facts? And do this double-blind to prove no bias? If you only tested commercial batches with correct formulations, then you're not really conclusive about rates of both Type 1 and Type 2 errors. But any valid metrology is a worthwhile advance in engineered quality.

It's arse about. If you measure your dry cement mix and then your water - all by weight - prior to mixing, it saves all the hassles - after mixing.

Here’s a good video in case you’re a total concrete noob like me: kzfaq.info/get/bejne/qL2GdN2EmsrZcac.html It will probably help you understand this (Tylor’s) video better.

Last year with an oat of -5c and overnight of -10 the contractors poured by 1600, the next morning they stripped by 0800. It was green and steaming, they backfilled 2days later without a floor system. A big part of our problem is code/building inspectors(paid for by builders/government) not doing a proper job. I actually was told by the head of building inspection services, " it is not my job to babysit contractors" wrong that is your job. I had to go to new building insurors where they threatened to avoid the insurance before they wou!d stop(until caught the next time)
