    Let me tell you: The lime is used to make the cement. The gravel pits are there to get the gravel. That is two different things.
    The limestone gets burned to get the active ingredient in concrete.
    You still need lime to get concrete. Recycling rocks and concrete can replace gravel for the most part.

    Here in the USA the need for this service has in many places become tied into growing environmental impacts from demolition material being cast off to illegal dumps; either to avoid the cost of hauling to commercial recyclers, or the absence of localized materials recycling operations.
    A really well appreciated and most likely profitable favor to the demolition industry would be to invent a rock and concrete crushing system that was more appropriately scaled and costed to job-site operations; the size where the throughput needed from the crushing system is not measured in multiple tons per hour; more like 1/2 to 1 ton per hour.
    Instead of having to pay for hauling castoff rock & concrete to commercial operations, contractors could process the material into forms useful on the jobsite, or possible to be sold to other parties. This would also cut down on them simply calling up people to dump the material "anywhere we can't see it", which in many locales has been and still is a growing problem.
    Not only would this open up new sales/leasing/rental business for the machinery, but would have immediate impact with environmental concerns over the swiftly growing number and volumes of illegal construction materials dumpsites.

      Here in Texas, we do haul most of the material to quarries where it is recycled. Much of it goes to the cement plants to be reprocessed. Type 1L (Ecoment Capitol Cement), or Type 1/2 LA (Alamo Cement/Buzzi-Unicem) is made with recycled material mixed with fresh limestone. It is used in home, commercial, and road construction. We use it for soil stabilization in spread operations and budget conscious readymix companies. I am a cement tank hauler. I haul it all the time. Very good for it's application, and economical. There are companies in Houston that have been recycling used concrete for decades. Near Austin-Bergstrom airport, there are several quarries that do it, also. Very little goes into landfills around here nowadays. I agree, more demolition operations need to step up and recycle their waste. It just isn't necessary or cost effective.

    I LOVE recycled concrete! My home is located on a private, three mile long gravel road which homeowners are required to maintain. Several years ago we had trucks lay down a 6-8" thick layer of recycled concrete on several hilly grades - our problem spots - prone to erosion, and once the material packed down, it's proven to be nearly as durable as poured concrete.

    when we recycle, we also reuse the energy used to obtain the materials. Not exactly, but you get the idea. We pulled something from the ground, spending say 3 energy, recycling it costs 2, net energy gains 1. plus that material itself is not easily replaced, it can be found in other places, but that is not the same as actually replacing it, that is just using up more of whats available to be used.

    This video conflates the need for aggregate (gravel and sand) with the need for cement. The gravel aggregate can indeed use recycled (crushed) concrete, but sand is more of a challenge, since its properties change during processing. The cement must still come from limestone, which is what is shown in the quarry. The "cracking" of limestone -- the separating of CO2 and CaO from the CaCO3 -- is very energy intensive and produces a lot of CO2. This problem, central to all use of cement including in concrete, is not addressed at all in this video. So, while reusing the aggregate is good, this does not tell the whole story.

    I've finally come across this in English. I was never specifically trying to find such but hearing this in a narration which I understand affords me clarity regarding the content. Demolition waste, if re-processed to required standards, can go round again in construction. It does not have to be creative disposal, such as golf course fill, or landfill liner, or sea breakwall crap, or road base. Government needs to underwrite correct re-processing facilities for it to meet construction requirements, then that be made manditory and compulsory per minimum percentages across the entire construction sector.

    In my town, in the 1990s, tons of metal that had been used in a local hospital's x-ray room, eventually went to a local scrapyard/landfill. The metal came from tables, carts, structural applications, furniture, equipment, machines,..all with high metal content. No one labeled it as contaminated or tested it. There were no safety protocols for this type of recycling, and to this day, I don't know if there is any laws or strict guidelines protecting us from this reckless practice. So eventually some of the furniture and including stainless steel tables, were plucked out and found there way into junk stores, in addition some of it was stolen from the landfill pile, by pickers. A year later, some family is dying from extreme radiation poisoning, and nobody knows why. The authorities think the problem is Radon gas, and chase some other false leads. All the while, it is the stainless steel counters in their kitchen, and other furniture, that they bought at a junk store. It was eventually discovered, what was going on. Though it wasn't reported on in a serious manner. And it was never talked about again,.....and no new safety practices were enacted or announced. (As far as I know) It was never discussed again in the local news papers. I only remembered it, because I buy used furniture from junk stores, too. Recycled concrete could contain high levels of radioactivity as well, and who would know.

Instead, they are mostly either pulled down to be replaced with something else or are pulled down after being abandoned for a long time. European building practices are extremely wasteful.

Furthermore, by using recycled concrete scrap, you can decrease your expenses, while also doing your part for the environment. The best part is that you’ll get to enjoy all of the benefits without having to sacrifice on quality.

      But I can go to beach and find rocks that clearly moved after being fractured, then the fracture was filled with liquid quartz that then solidified to lock the rock with cracks misaligned.
      These rocks look like spider stones.

    what happens if the concrete in for recycling was a poor grade of concrete, made with beach sand that had salt.. or decomposed granite was used as an aggregate .. would that effect the long term life of some of the batches of new concrete in the decades to come..

    I used to test concrete cylinders in the USA. We would turn off the machine a split second before they break. They are very loud, dusty, messy, the shards are sharp and it wears out the expensive machine faster if we let it go to full break. Sometimes my fast reflexes were not fast enough. They sound almost like a small shotgun.
    Another subject is the lack of dust masks. These people are going to suffer with COPD if they do not protect themselves with N 95 or better dust masks.

    This has some major potential problems. Recycled concrete can be loaded with potential low strength conglomerates. Buildings from so long ago did not have the advancements of today’s engineering. Different structures require stronger materials pending on the bearing ratios they must hold.
    700kn seems strong enough right? Until you understand the test procedure. By looking at the test sample assuming it was .02m3 cube, this would equate to less than 30mpa.
    I personally wouldn’t be using this for any structural foundation or suspended applications.

    The concrete company mixes their batches properly and then on site, the contractor tells the concrete driver to dilute the mix. Within a year, the concrete starts to fall apart. That's how it is where I live per a concrete mixer driver I know.

    Errr...
    It seems to me that the concrete is not reused in the sense that cement is made from it again. That would require crushing to powder, further separation and re burning.
    It is used to replace the fillers that normally go into concrete. Great of course to use it like that and decreases the raw amounts needed for those, but does not limit the amount of cement needed in any way. Thus what the video started with, the production of cement, is not affected in any way by this type of recycling.
