This is far worse in a place like india. It’s pretty much impossible to find anything technical or product related that’s localized. The only non blogspam source often is <vomit/> quora.
For example. Most construction happening in india now uses something called M-Sand. I actually CANNOT find what the hell it is except from some company websites or random YouTubers blabbering non engineering garbage about it.
You've probably already google-fu'ed this, but its ~4mm crushed granite used as a concrete-sand substitute where granite/gneiss sand isn't available.
Most construction materials businesses sell locally by word of mouth, and if they paid for a website at all it's old and still using http. So Google drops them.
What is there to know about it? Looks like it's just sand that's produced by crushing stones in an industrial process, rather than relying on rivers to do it for you. It's probably used as an aggregate for concrete.
Could be due to the difficulty of getting sand in the region. I watched this fascinating Vice documentary about illegal sand mining in the region. I had no idea it was such a big deal.
It was really fascinating watching the Grand Tour Vietnam special on Amazon, you could see all this sand mining happening in the Mekong river, though no one commented on it.
Honestly disappointed at the documentary but curious about the topic. They kept repeating the exact same thing over and over and over again, dripping little bits of info.
