Hourglass running out: Sand becoming scarce world over due to soaring demand

沙漏正在耗盡：由於需求激增，沙子在世界範圍內變得稀缺

The world’s most consumed raw material after water and an essential ingredient to people’s everyday lives is slipping through our fingers, scientists warn. Sand may become a scarce resource due to high demand, they say.

科學家警告説，除了水，世界上消耗最多的原材料和人們日常生活的一種基本要素正在從我們的手指間溜走。他們説，由於需求量旺盛，沙子可能會成為稀缺資源。

“Statistics show that it takes ten tons of sand to produce every ton of cement.” Whoa!

I think that’s some kind of logical contradiction. Sand is only one component of cement,the other is gravel and cement and water of course. You couldn’t get one ton of cement by inputting 10 tons of sand! The ingredient known as cement is made from limestone,not from sand. It’s limestone that is heated until the limestone becomes a paste like consistency. The word cement has two connotations.

“數據顯示，生產每噸水泥需要用掉10噸沙子。”哇!

我認為這是某種邏輯上的矛盾。沙子只是水泥的一種成分，另一種情況當然是碎石和水泥和水混合。你不可能用10噸沙子得到1噸水泥!水泥的原料是石灰石，而不是沙子。將石灰石加熱，直到石灰石變成粘稠的糊狀。水泥一詞有兩種含義。

maybe if you include the roads, etc to transport it, roads, storage areas and so on

也許如果你包含道路等來運送它，道路、儲存區域等等

Modern Cement industries use low grade Bauxite, Steel mill coke residues and fly ash to produce cement

現代水泥行業採用低品位的鋁土礦、鋼廠焦渣和粉煤灰生產水泥。

the report says ten tons of sand to make one ton of cement, not eleven tons.

報告説的是10噸沙子可以製造1噸水泥，而不是11噸。

My thoughts exactly. I did stone masonry for more than 25 years. This does not compute. You cannot put 10 shovel’s full of sand in the mixer and get one shovel full of cement out. This must be an error that the editor missed.

我的想法也是這樣。我做石工已經超過25年了，這種算法不合實際。你不能把10鏟沙子放進攪拌機裏，然後拿出一鏟水泥。這一定是編輯疏忽造成的錯誤。

No cement contains ZERO sand. What the ignorant “climate scientist” is probably meaning is concrete, which is about 30%-35% sand. That’s why you should talk to a civil engineer if you want to know about concrete and sand usage, not a climate scientist. Their main function is to scare people by making ridiculous alarmist claims, as we see here.

水泥中不含沙子。無知的“氣候科學家”的意思可能是混凝土，它大約含30%-35%的沙子。這就是為什麼如果你想知道混凝土和沙子的用途，你應該和土木工程師談談，而不是氣候科學家。他們的主要作用是通過發表荒謬的危言聳聽的言論來嚇唬人，正如我們在這裏看到的。

The only ignorant is the jurnalist that threw this numbers, the scientist never talks about this in the webinar - that it’s lixed in the article.

唯一無知的人是拋出這個數字的記者，這位科學家從來沒有在網絡研討會上談論過這一點——文章裏有鏈接。

RT is as emotionally manipulating (and minor quality journalism) as the usual mainstream, just in a different direction.

《今日俄羅斯》和常見的主流媒體一樣操縱情緒(以及低質量的新聞報道)，只是方向不同而已。

@Rocky_Fjord

Article author made this mistake not the author of the study. There is a lix to the original webinar, it would be wise to give it a read and don’t throw blame on the scientist.

文章作者犯了這個錯誤，不是研究的作者。這裏有一個原始網絡研討會的鏈接，明智的做法是讀一下，不要責怪科學家。

Probably downloaded from the internet somewhere. Besides, cement is made from limestone and shale, not sand. Why would you use sand? Sand is used when you’re making concrete. Along with stone, cement and water…

可能是從網上下載的。此外，水泥是由石灰石和石料製成的，而不是沙子。為什麼要用沙子?當你在造混凝土的時候會用到沙子。還有石子、水泥和水……

This will somehow translate into a new tax.

這將以某種方式轉化為一種新税。

I don’t know whether Sahara sand is suitable to make glass. I do know that it is unsuitable to make concrete or mortar and that was what the article was about.

我不知道撒哈拉的沙子是否適合做玻璃。我確實知道製作混凝土或砂漿是不合適的，這就是這篇文章的內容。

Sustainably grown timber is the best option.

可持續種植的木材是最好的選擇。

Bamboo is a grass that grows fast, is strong, is renewable and can be formed into laminated beams. It would be a viable alternative some dimensional lumber and microlam beams. But I do not know if would have the compression strength that concreate has.

竹子是一種長得快、結實、可再生、可製成層壓梁的草本植物。這將是一個可行的替代一些規格木材和微型橫樑。但我不知道它是否具有混凝土的抗壓強度。

Sooo, at the climate accords they decided fuel and raw materials must be made more expensive annually to discourage there use. 

So now as prices increase they say it indicates shortage.

Are we paying attention yet?

因此，在氣候協議中，他們決定必須每年提高燃料和原材料的價格，以阻止它們的使用。

所以現在隨着價格上漲，他們説這表明短缺。

我們注意到了嗎?

This UNEP expert Pascal Peduzzi should go (back?) to school, or at least read wikipedia. Cement is NOT made with sand. The process of making cement uses limestone and clays.

聯合國環境規劃署(UNEP)專家帕斯卡·佩杜齊(Pascal Peduzzi)應該回到學校，或者至少閲讀一下維基百科。水泥不是用沙子做的，製作水泥的過程中使用石灰石和粘土。

@czerenkob

Things Pascal Peduzzi didn`t say in his webinar that YOU didn`t bother watching. 

Maybe if you spent more time watching what actual scientists are saying than wasting your time with Wikipedia..a good 1/3rd of which is utter nonsense you MIGHT learn something.

帕斯卡·佩杜齊在他的網絡研討會上沒有説你不想看的話。

也許如果你花更多的時間觀察實際的科學家在説什麼，而不是浪費你的時間在維基百科上，其中有三分之一的時間完全是胡説八道，你可能會學到一些東西。

Brownbalrog

@czerenkob

Ahh a fucktard if you had watched the Webinar instead of just the article you would find that Pascal Peduzzi didn`t say that at all. Try again.

如果你看了網絡研討會而不是那篇文章你就會發現帕斯卡·佩杜齊根本沒這麼説過。再看一次。

@Brownbalrog

Two replies? I am flattered.

Please, note that I wrote about what was in the article. If I wanted to write about the webinar I would watch it and then comment under it, if allowed and necessary.

兩個回覆?我受寵若驚。

請注意，我寫的是文章裏的內容。如果我想寫關於網絡研討會的文章，我會先觀看，如果允許和必要的話，我會在下面發表評論。

Running out of sand?

Sand and gravel are now the most-extracted materials in the world, exceeding fossil fuels and biomass (measured by weight). Sand is a key ingredient for concrete, roads, glass and electronics. 

Massive amounts of sand are mined for land reclamation projects, “shale gas extraction” and beach reclamation programs.

沙子快用完了?

沙子和碎石現在是世界上開採最多的材料，超過了化石燃料和生物量(以重量衡量)。沙子是混凝土、道路、玻璃和電子產品的關鍵成分。

大量的沙子被用於土地復墾項目、“頁岩氣開採”和海灘復墾項目。

I know this is going to come as a shock to you..but sand has many different types and shapes..not all of it is good for construction. You can try to make a building out of sand from the Sahara..i won`t go anywhere near it and i`ll be impressed if you get more than 2 floors up before the entire thing collapses..but you can try.

我知道這會讓你大吃一驚……但是沙子有很多不同的類型和形狀……並不是所有這些都適合建設。你可以試着用撒哈拉沙漠的沙子建造一座建築，我無論如何也不會靠近它，如果你在整個建築物倒塌前爬上兩層以上，我會很驚訝的。但是你可以試試。

Sand is everywhere; in deserts, river beds, estuaries and laying at the bottom of all our oceans! I guess April 1st has come earlier this year? Besides, as others here point out, cement (the ordinary Portland variety) is made from Limestone rock.

沙子到處都是：在沙漠、河牀、河口和海底!我猜今年4月1日來得早了吧?此外，正如其他人指出的，水泥(普通硅酸鹽品種)是由石灰石製成的。

Well, you guessed wrong, most of the stuff you mention is completely useless in construction.

嗯，你猜錯了，你提到的大部分東西在建築中完全沒用。

Paul Chapman

I’m guessing the Sahara desert is going to be clear of sand in a few weeks then, replaced by prime fertile land. 

Shocking for the environment eh?

我猜撒哈拉沙漠在幾周內就乾淨的沒有沙子了，取而代之的是肥沃的土地。

對環境來説令人震驚，是嗎?

Desert sand cannot be used in construction or for cement concrete, due to its structure

由於沙漠沙子由於其結構，不能用於建築或水泥混凝土。
