Thereâs a lot changing in the construction industry, and a lot of growth in the need for materials like sand and gravel. But I donât think itâs fair to say the world is running out of those materials. Weâre just more aware of all the costs involved in procuring them, and hopefully taking more account for how they affect our future and the environment.

Fun fact: 2% of the world's yearly consumption of sand goes through a clear perspex box in Grady's garage.

"Hammer the point home"... "grain surgery". The puns in this video are off the charts, and I'm all for it!

Field carpenter here, I've spent some time working in construction quality control for a little bit which means I'm working alongside engineers on a regular basis. We don't so much use concrete in my niche industry, but we use grout for the work we specifically do. We have 3 different engineered ratios of mix to water that we are supposed to use. One of them is flowable. You have no idea how many workers I've seen walk on one of my jobs and want to mix it by eye and feel because "this is how we always mix it" instead of following the engineering. We usually have to hand pump or funnel it so it has to be off the flowable chart. Then I see them with their full weight on the pump handle because they don't understand why their stuff mix can't go through the equipment and it costs the company and customer money in wasted materials and manpower to clean the equipment, and time to remove the grout that has voids and bubbles.
I guess what I'm getting at is that I fully understand the frustration that happens when the guy with the clipboard looks away and the workers do what they feel is better than the spec book

1:50 "Sand is any granular material that is at least 85% sand."
Hmm yes the sand here is made out of sand.

"Those costs have always been there. We just externalized them onto the environment and our future."
Strong line here.

"The costs have always been there, we've just externalized them onto our environment or our future" is a statement that holds true for SO MANY THINGS where people complain it's getting more expensive!

I worked as a concrete technician at a plant a while back, during which we transitioned from using riverbed sand to crushed rock for the 0-4 sand. The plan was also to phase out the 0-2 in the same way. 0-8 and 4-8 etc were always crushed rock. This was done due to sand running out close by, and continued extraction would have had an impact on the ground water.
You hit most of the points, like how you have to adjust V/C ratios and add some chemicals to get the new recipies, but for us the most noticable difference was the wear and tear on our mixers.
Parts that used to be replaced yearly now had to be changed 3-4 times a year. The sharp edges of the crushed stuff does not play nice with machinery.
Anyhow, I think it is somewhat true that we are running out of natural sand in many places. But it is always a local shortage.

as usual it's not that we're running out of X, it's that we're running out of CHEAP X

How often you said "I also made a video on this" really showed me how much I have learned watching this channel over the years. Thank you so much!

I like sand. It's fine and useful and ubiquitous and is everywhere.

Alright, so the key takeaways are:
1) manufactured sand is more coarse and irritating due to the sharp edges
2) natural sand is better at getting everywhere due to the rounded grains reducing friction

Tell the truth. We don't use sand from sand dunes because we're afraid of the worms.
That and the spice is crazy valuable.

The thing here is that... not all sands are equal. Different industries require different types of sand. For example, silica sand for glass. However, the sand for glass is totally inadequate for use in fiber optics. The semi-conductor industry also uses silica sand and, again, it has to be very carefully chosen. I've heard some talk about "concrete sand" and that's mostly bunk. What is more of a concern is that there really is a practical limit to silica sand and that's becoming more and more of a concern as we consume more of it in industry after industry.

The phantom giggle hovering in the room as you say "glected"... delightful.

I'm a geologist, and it's so novel to see things from ths "other side of the fence", so to speak. Even just hearing about the way sand is classified is so interesting! Of course, I knew that the level of specificity required for our measurements vs yours is different, but there's something very strange about seeing it in practice.

Excellent video! What a weird thing for a fake sand fact to have spread so far and wide. A good reminder to be careful about repeating things I really don't know anything about.

Answering the titular question in the first 3 seconds of the video. Give this man a medal.
