concrete_solutions dafremen The problem of cement pollution is a big one. Why should the rest of us pay the price of removing the salt from ocean water after profit seekers deplete our fresh water reserves? Cement can only be made with fresh water or its weakened. And cement is the second most consumed resource behind water (which makes sense, since water's used to make cement.) There are materials out there being developed, but no one seems to want to use them. The media keeps portraying the problem as one of "stubborn cement companies that don't want to change." Academics and richies are ever such shitbags, trust me. I've studied them for years..from the inside. In reality, it goes like this: Step one, how do you insure a building made of a new material designed to replace concrete? Concrete's been tested and improved for centuries. Who wants to get behind a 100,000,000 ton dam that's made out of a material no one knows the wear characteristics or durability of? Not any insurance company, that's for sure. And no investors will get behind it if their liabilities aren't covered. And what about academia? How can you teach structural engineers about a material you don't even know anything about yet? How do you keep from getting your ass sued off when the material fails catastrophically? Will it? Who knows? These people aren't men. They're mice. A sad reality of modern mythology. So we'll keep making cement the old, dirty way. We'll use it to produce "eco-friendly" projects. But it's not JUST because of cement companies. No, they're just glad no one with money's currently pressing for a solution. 210906 what's it to you? who go blather from
