The Romans used volcanic ash in concrete and that's why the acquaducta are still standing. Portland cement uses fly ash which is a by product of incinerators. The ash prevents the concrete from falling apart.
This Yahoo article says a lot of nothing. Only that, hopefully, maybe, we kinda, might, have a chance ....
Sand still is an important ingredient and coffee grounds will not replace sand. They might replace the ash part of the equation but not sand.
As some of us know from hard money. Soft money or cheap money creates scarcity. So as long as we depend on cheap fake Fiat all resources will be scarce and tax based upon "environmental" nonsense will be just another method of extracting resources from already poor people.
This study clearly states that this would help reduce sand usage so you keep commenting it wont touch the sand when the study states the opposite.
The sand used in concrete is an issue because we are running out of easy places to get it from. It sounds crazy but desert sand it to fine which is why river sand is the most common. However, we have seen over the years “sand gangs” or criminal groups that literally come in one night dredge out a river and are gone in the morning. Replacement is needed for our current approach.

The article is wrong. That's my point and the writer does not understand how concrete is made. It's meant for people who do not understand what concrete is. The recipe for concrete was lost until the early 20th century so, like most modern technologies, we assume we know so much but we don't concrete was used thousands of years ago. Concrete also is a product that can be reclaimed.
And with the continued use of fiat that has can be produced infinitely there will be a shortage of food, water, sand, concrete... because the controllers of fiat can front run those who have to work for fiat.
I have an extensive and intimate knowledge of concrete. My grandfather, father, uncles and myself have all been working with concrete for many years. I've been an estimator, form carpenter, foreman and superintendent for many high rise projects, bridges and other civil and commercial ventures.

Wow this person knows his concrete design 👏 but I disagree on what causes scarcity. Only thing limited for humans in this universe is time. Hard or soft money doesn’t solve human death and what comes after death.

Easy money or soft money, aka Fiat currency causes scarcity because it only benefits those who already have it at a very high quantity and also it benefits this who can print it or can borrow it by making promises. That's how they maximize their time and confiscate yours.
Learning to find hard money abd assets that are not easy to confiscate like Bitcoin increases the amount of time you have to make choices.

How? Those who have it die. This argument doesn’t make any sense. The hardness of Bitcoin is computer code. That humans agree to follow. Why? They think it will serve them well in the long term. But having hard money doesn’t make time more abundant. Individual time. Hard or soft money is indifferent to the amount of time you have on earth.

You are already wasting your time using computer code. Bitcoin frees you to increase the choice of your time. If you are merely concerned with time then you definitely would not waist any of it typing out responses. But you do use computer code and you waist your time arguing about time and that code is just code when you yourself use it to negate the object of code and pretend that you are outside of the realm. Even your nym tells the truth that you are just being a contrarian and not sincere.
