Where is the evidence too much LED will send you blind, please?

Thanks for the explanation.
I don't use the tyre walls for food, just flowers, greenery,  insect attracting plants, low stuff.
I live in a hot dry climate, so anything with a bit of soil can add a bit of brightness to the place.
I am with you on using them in a house that is well sealed, I have no proof they don't cause harm, but I can smell them when I carry them around and just don't think its a good idea
to live in something that smells.

I have used them as low walls to stop that freezing breeze that can come in around a fire, I have built low fence and gateway entrances on properties with them.
I see their beauty in the use of an object that is usually a problem to get rid of.
But I can say I have read of experiments in turning them into fuel for cars etc .
I just cannot recall the full story, but if that happens, we may not be able to get them anyway.

My outdoor kitchen has been working for 40 years. Its located in my "tuscany" courtyard that is still unfinished.
I have a BBQ set up, a gas Oven, a sink 12 foot long with a large bowl.
All my tools hang on the back wall, I have a shelf behind the sink 6 inches wide and it holds all the small stuff, condiments etc.

The table and cahies can face the sink or an open fire I have opposite the sink etc.
We sit there summer or winter.
Lately, with 45 degree days I have added shade cloth over the iron roof and fitted a misting system to keep us cool, in winter I light small firs that we can cook on and sit fairly closely to.
I am sick of seeing people have fires so big you need to stand 12 feet away.
Its just wasteful.
I had some tenants once who used my 2 years suppy of wood in 8 weeks and complained the courtyard was not big enough to allow them to sit away from the fire.
I was not amused

I understand, I am in a similar situation, retired sidecars to race, hot rods to build.
There is just not enough hours in the day any more!

The tyre walls are not filled in the earthship manner, I did not state that. They are filled loosely with soil good enough to grow things in,
whether you plant food or ornamental that is not the issue.
As for beauty, that is in the eye of the beholder, and I will disagree with your opinion.
i work from the aspect of reuse, low cost and tyres meet that criteria.
As for outgassing, leaching etc I am still waiting for facts, not guesses or assumptions.

Cant you use a concrete mixer, either petrol driven or electric. Hand mixing is a hard way to go about it.
As an Engineer, I would suggest a lot of the problems may be coming from that embankment at the back.
Your description of what is happening suggest water is pushing the wall over, along with the solid just getting damp and loading the wall.
Many small walls years ago were built with nothing to stop them leaning over with time, caused by the weight behind it, even low walls, 2 feet.
I would have a good look at shifting that soil back, sloping the ground to remove the need fot a wall if possible, and improving the drainage so any water can swing past the hues.
If its not possible to dig back because of boundaries etc, remove the wall and build something designed for the job.
There are kits available that would required galvanised posts inserted into holes 2 feet deep for a 2foot wall and concreted in. Then concrete slabs, or thick timber slabs of suitable wood installed behind the posts.
AS you back fill the wall, start with screenings and a slotted pipe, so water pressure cannot build up.
That pipe needs to drain around the house again.
The screens column should be about 5 inches wide as the soil is backfilled and if you can place a mat like shade cloth as well, between the soil and the fine 1/4 inch stones to prevent soil washing into and blocking the stones,
thats another better outcome.

there is a product called "Belt slip", that has the same effect as putting a sticky substance on the belt, obviously to prevent slipping.
It sometimes helps.

I have designed concrete mixes in the past as a Civil Engineer.
There are a few points that need clarification.
'Cement quarry rocks' are really aggregate, [ stones], crushed usually from basalt outcrops, that become the aggregate or stones in a concrete mix.
Similar aggregate is used as the base for roads, in different sizes big ones at the bottom and smaller at the top, it is used as filling under concrete slabs
and anywhere are hard wearing non soluble material is required.

In fact in Australia, the dust from crushing plants is sold as Rock Dust and has many minerals which are claimed to be very good for the soil.

Cement is an additive to concrete, not the name of the final product.

Concrete is made from a mixture of Aggregate, sand and cement.
By varying the size and type of those items different strengths can be achieved. Generally the high strength concretes have more cement.
Cements themselves can vary and again have different results for different outcomes.

Admixtures are additional items put in the mix to slow down curing, speed up curing depending on the weather, some make it waterproof,
others, with different aggregate sizes make it flow better when being put inside hollow blocks.

Here Fly Ash has been banned, it creates problems for concretors, people wholly the concrete, and has caused issues with the concrete not gaining its full strength.
Concrete dust is as bad for humans as any other dust and care needs to be taken when grinding or cutting it.

Used properly it is a product that has enabled the type of structures people expect to have in communities today.

The use of lime with it changes its characteristics and many people like the benefit of it. For instance Limecrete is fantastic for exterior patio floors,
because it does not reflect heat the same way a concrete slabs does in hot climates.
I hope this helps with your understanding of the variations and the uses of concrete.
to label it as bad is something many would dispute.

I use tyres as garden walls, I stack them to the desired height, I use tek screws as I build them to keep them connected. I offset each so the wall is a bit wider than the diameter of the wall.
Each column of tyres has exactly the same sized tyre so they feit together better.
Sometimes I fill the tyres as I build them up so water cannot collect in them to breed mozzies.
I have capped some with not fill for the same reason.
Others I have filled with dirt, not rammed its too hard.
Others I have filled with old bottles, rocks, building rubble I have scrounged,
I have kept some low, say 2 or3 tyres high and grown plants in them.
I reckon they are great and can be used in areas where any proven issues in the future will not be a problem.
I have seen some wound with mesh , and had either ferro cement or lime mortar plaster put over them.
I live in a dry climate and have carried out no tests what so ever on them.

I have used them as moulds for concrete blocks to go under shipping containers to create a good sized pad.
