Processed Glass Aggregate 

Pennsylvania voted for Fetterman. I have no respect for the state.

@@robertwoodpa6463 Don't be jealous, it's not becoming.

That "fact" is so utterly wrong... But with americas education system you are not to blame for not knowing basic things.

Probably a good idea sand to make concrete is expensive and glass aggregate would keep it out of our land fills

Thank you!! 😊

You totally ignore the fact that melting virgin silica sand into new glas requires a lot of energy too.

@Langonica: I think you are not understanding the big picture.

@@GFSwinger1693 show me the big picture

Want me to google that for you?

It IS being used in Europe! My friend’s son is establishing a plant In Arkansas and his machinery is on order from Europe.

Oh man , that sucks - sounds like an unholy marriage of corporate shennanigans between the ambulance chasers and the guy who owned the quarry! Just like when Trump's minions organised an astroturfing protest in Times Square with paid GOP activists/unemployed actors pretending to be outraged about the building of wind turbines in view of one of his golf courses....in Scotland!!! Our planet is infested with these turds and lots of judges are clearly in on it too.

I knew a guy who new a guy!

This seems just made up. This stuff in no way resembles any glass container. "Legislative protection is required for the product to ever become used widely."- this also seems like an oddly specific opinion for a random youtube comment.

Obviously PGA in no way resembles a broken bottle possibly useful in a bar fight. That is the point. Fraudsters would fake pictures of broken bottles glued down with asphalt and claim "pain and damages" for the injuries suffered when they wiped out their motor cycle. Most of the time the accident occurred on roads using conventional flint rock, often by other companies. The court and lawyer costs would still be well in excess of $10,000 for each and every case. Many cases. Hopefully this road department making this video isn't advertising for their own fake lawsuits. My advice, take down the video and stop using glass.

@@rochrich1223 you can claim anything you want but it's going to be thrown out after the first hearing. Unless you can point to a specific example I am going to say this is some sort of Urban legend

i heard it's good for asphalt but concrete requires porous materials to bond together. Glass doesn't absorb water so I think it wouldn't work

For the same reason you cant use desert sand. Too smooth.

Concrete would not be as strong if you use PGA, which is shown in this video, where pieces are still chunks of glass, opposed to grinding it into powder (which is more labor intensive). For reference: www.concretedecor.net/departments/concrete-placing/waste-glass-in-concrete-has-advantages-and-disadvantages/ "The strength of concrete containing glass powder as a cement replacement material is approximately equal to that of concrete containing only portland cement. However, its durability properties outperform that of conventional concrete. The strength of concrete containing glass aggregates is 10%-20% less than that of concrete containing mineral aggregates. This reduction in mechanical properties is due to the lower strength of aggregates as well as less bonding between the glass aggregates and the paste compared to the mineral aggregates."

There’s a product called glavel being produced in Vermont that is thermally expanded recycled glass that can be used in place of gravel in concrete and gas insulation as well. But it’s more expensive to produce than this crushed glass product.

pro internet tip, type any idea you have with the word scholar at the end to get real information on the subject. crushed glass aggregate scholar, I've read many of the glass concrete articles its good stuff

Glad you enjoyed it! :)

Our pleasure! 🙌

RIGHT?!

Thank You! 😊

Every developed country either reuses glass - this is the best Form of recycling or it is collected separatedly and then recycled to new glass bottles since it is reusable basically in an infinite way. This 1960s variant of collecting the trash together with the glass and separate it later to downcycle it is the american "we are stuck in the last century" way where no one thinks about environment or saving energy or even efficient processes in the first place. But what can you expect from a country using weird legacy units instead of commonly used units like meters and kilos, discovering insolation on houses as a next big thing and having overhead power lines depite having 120 years of time to bury these lines and then complaining about power outages after every hurricane...

You're right! In New Hampshire, we have some towns participating in a "clean glass" program where glass is turned back into bottles or fiberglass, but the contamination rate must be very low. Other towns with higher contamination rates (from things like ceramic, pyrex, etc.) participate in the PGA program where glass is ground up and can be used in numerous road construction projects.

I can't believe those workers weren't wearing respirators.

Probably a sand/aggregate mixture

I know for a fact Pa has used PGA in asphalt in the past. Recycling it wasn't as common as it once was, probably due to the vastly use of plastics.

The "glitter" is a substance called MICA that is in some gravel in the mix design. It is not harmful to the hot mix, just sometimes annoying under certain conditions.

Yes, but it would not be as strong if you use PGA, which is shown in this video, where pieces are still chunks of glass, opposed to grinding it into powder.

probably no. That process is going to require a precise composition of glass to get the right size and type of spheres.

Unfortunately, no. Short answer is that the reflective angles won’t work.

Big difference between a quarry and dredging.

@@Kriss_L Gravel and sand dredging for aggregate is still called a quarry.

@@frequentlycynical642 Never heard that before.

This video is a couple years old. It isn't really "kept out of sight" anymore as more towns use PGA in roadwork.

Depending on where you live, you can still get $$ back for returning your glass bottles!

no it can't cement or concrete needs moisture to bond materials together and this material does not absorb water it actually repels it so it would be good for a base but will not work in the actual mix

You have to keep the coloures of glass separate to reuse it as bottles. Hard to get the public to do that.

@@davidapp3730 That is exactly how we recycle around here.

I think the distance to a recycling plant is the problem, in Europe we generally don't have that problem.

I'll bet the vast majority of recycled glass in Europe also goes to the landfill. It is the sales pitch/propaganda that it is actually made into real glass products. A 1/10% contamination with ceramic/rock will render the melt waste. Window glass will contaminate container glass the same way. God forbid someone thinks they are saving the environment by recycling cut(leaded) glass.

It would work. The problem is that unlike local DOT, who can get it from their own local recycler, a railroad company would have to source it just like gravel. And they already have contracts for the gravel.

It doesn't lower the freezing point of water like salt does, so it won't help thaw any snow or ice already on the road.

@@stepaushiThey are talking about using it like sand grit. Adds traction, not to melt ice.

Thats what I meant. Traction. Mix it 50/50 with salt and done.

@@mander6447 Ah, okay √

The dust when it dries is too good for your lungs.

Many places do, but only "clean glass" can be turned into new bottles and jars (or fiberglass!) They cannot have any contaminants like ceramics, pyrex, mirrors, etc. - things that folks think of as "glass" but have a different chemical makeup (and would thus make a subpar new product...and no one wants their glass bottle to break!)

What do you think making cement, mining and crushing rock causes?

@@id10t98 cementosis

@@LegendLength Does working around halogen lights give you halitosis?

Glass is silica, it is not crystalline silica... Should wear dust masks anyway.... Glass sand is OK that is why it can be used for Environmental shot blast material...

Explain that further. Show us a cost analysis.

@@LarryDickman1 Don't hold your breath waiting for that CBA. ;)

@@LarryDickman1 do your own, start with the collection process, maybe you’ll prove that it’s only 7 times more expensive.
