@@PROVOCATEURSK Exactly. It's capitalism but not for the reason you seem to think. Most sand is too impure. It's polluted with different minerals, organic matter, and rocks, which makes it unsuitable for a lot of different projects. That's why you need sand that's more pure. You can't use sand filled with impurities to make window panes, for example. They'd crack and be too fragile. It's cheaper to import pure sand that occurs naturally in certain places on Earth instead of trying to purify already existing sand, which means capitalism has done what it's supposed to and actually made the product in question (the sand) cheaper.

I think that is true, that there may be other uses for desert sand, but it is not useful for construction "at scale". There are physical limitations in play here. To make a concrete structure that is both light enough, and strong enough to be useful, angular aggregates are needed. Round sand pumps easily, and would work vary well for ballast slurry, but that product is seldom used for anything anymore. It made a great ablative layer in an early 20th century bunker, but that kind of "mass based" structure is uncommon today. Dubai doesn't need any new pyramids.

May I suggest a few Geography courses at your local University... only 25% of the Sahara Desert is actually Sand. Top soil is mostly compost of various types of fauna (plants). It blows and washes away quickly. Look at any river delta to see the sediment (soil) washed down river by 'fast' flowing water. When the river hits a body of still or slow moving water, the load capacity of the water is diminished and thus... deltas are filled with sediment. Without the compost (organic - decayed carbon based flora), very few things can grow anywhere.

It was said in the video that desert sand is not good as it's too perfect / particles are too round and uniform. But it didn't mention whether any of it is (or can even be) used for cement mix, of which 60% is sand. Can it be 10% desert sand and still be ok? Though, the video did say the construction industry uses sand from a local radius, always, so... it doesn't even matter

There is silver bullet solution and that is lowering usage of concrete, because while it is cheap it produces a lot of greenhouse gases and there are alternatives for some of it's usage. With glass you just have to make recycling of it better so you would need less of sand intake. Also they could try to use sand from deserts to throw it in dug spaces to check if it could turn into coarse sand. and the rest of the sand could be gotten from mining other things like it was suggested. Europe also has big problem with how much concrete they use in production as we have much bulkier homes compere to the American ones by I am not sure about this point as I don t know about construction in whole Europe and nuances

The solution is to use a lot less concrete. Hopefully engineered wood like cross laminated timber can begin to broadly replace concrete in the construction of midrise buildings and similar structures.

Hopefully we can shift away from using sand for construction to more sustainably produced construction materials like mycelium and hemp, although they're relatively new methods, they seem like much better alternatives

Hemp is not new, George Washington was a hemp farmer ,and the first composite plastics (you would know it as fibreglass) was reinforced with hemp fibre. By the way, plastics, which includes fiberglass resins are a waste by-product from the processing of crude oil and they contain chemicals called PHTHALATES, they are basically synthetic female hormone, plastic is causing femininity through the entire food chain and messing with our Endocrine system (hormone production). I think it is a greater threat to humanity than CO2.

What about crushing and refining demolition waste? in the UK we must have tons and tons of old bricks and concrete(made from sand and clay) that could be crushed and recycled. A lot of that stuff just goes to road fill. Instead it could be used for building projects?

I think there are building regs in Ireland that prohibit the use of building waste in filling in sites below floors and before the concrete slab is laid. Also there are huge problems with mica contamination in concrete blocks causing weakening and swelling and cracking of structures built with these defective blocks. The main reason that old building waste is not used in new construction is the lack of information on the nature of the waste and its performance when wet by subsurface water etc. Will it swell, weaken and crack? Conscientious builders avoid it for this reason.

Sand seems like a hard thing to run out of, but we might not be pricing it properly. If the extraction of sand also came with a severance tax it would price sand in such a way that there would always be some left. Rising construction costs aren't fun, but neither is suddenly running out of a resource

Might as well use it while you got it instead of artificially restricting supply while lining the government's pockets. If there's no natural sand left for them to use they'll go for the next-most economic solution and the price will rise to meet it. The market will adapt. Artificial control over sand prices will not cause the market to adapt significantly better.

Desert areas have two things, sand and sun. If you used a solar concentration system to rapidly heat sand passing by on a conveyor it would stick to a few neighbouring grains and after a bit of rough handling it would probably break apart again but this time it would have a much greater surface roughness. The engineering would be a b!tch though... sand gets into everything and destroys moving parts, especially when dry.

Lots of people saying something along the lines of make a 50/50 mix of desert and river sand. Unfortunately the load bearing ability is severely reduced when you add in round material to angular material. A visual example of why this wouldn’t work is this - Imagine a bowl full of legos versus a bowl of half legos and half ping pong balls. Then without removing any of the material, try to stick your hand in the bowl and touch the bottom.

Desert sand gives less strength but this could be compensated for by designing with a higher safety margin. We use desert sand for our concrete here and nothing collapses unless if it is poorly executed. And even then, concrete is a very forgiving material. I’m sorry but I can’t deny what I have been seeing all around me here. Nothing built with desert sand wants to collapse.
