英國(guó)工程師發(fā)明了一種特殊水泥，這種水泥可以使造成溫室效應(yīng)的二氧化碳從大氣中剝離。
據(jù)報(bào)道，這種水泥的發(fā)明者是倫敦Novacem的首席科學(xué)家Nikolaos Vlasopoulos。
Vlasopoulos說，新的環(huán)境友好型意味著水泥工業(yè)將從二氧化碳的主要排放者轉(zhuǎn)變?yōu)橹饕照摺?
用全球每年生產(chǎn)的20億噸水泥吸收掉全球5%的二氧化碳排放量，超過整個(gè)航空業(yè)的年排放量。
事實(shí)上，水泥需求的長(zhǎng)期趨勢(shì)是不斷增長(zhǎng)的。近日，法國(guó)農(nóng)業(yè)信貸銀行的一份報(bào)告預(yù)計(jì)，2020年的水泥需求將比現(xiàn)在增加50%。
傳統(tǒng)水泥業(yè)溫室氣體排放有兩個(gè)來(lái)源：生產(chǎn)過程需要高溫加熱，因此需要大量能源來(lái)加熱水泥窯以加工原料，利如石灰石。而這些原料在分解的過程中會(huì)進(jìn)一步排放二氧化碳。
但是到目前位置，還沒有找到一個(gè)大規(guī)模解決此基本問題的方法。
由于Novacem水泥的基礎(chǔ)原料是鎂硅酸鹽，它不僅需要的熱量少，在硬化過程中它還吸收大量的二氧化碳，使碳離子化。
據(jù)Novacem說，這種水泥產(chǎn)品在整個(gè)生命周期中每噸可吸收0.6噸的二氧化碳，
Novacem水泥對(duì)于其使用加熱時(shí)不釋放二氧化碳的鎂硅酸鹽申請(qǐng)了專利。它在加熱時(shí)需要的溫度也相對(duì)不高，大約需要650攝氏度。這使得總二氧化碳排放量為每噸水泥產(chǎn)生0.5噸二氧化碳。
據(jù)估計(jì)，新的水泥產(chǎn)品具有巨大的潛在市場(chǎng)。
由Vlasopoulos和他的同事在英國(guó)倫敦帝國(guó)學(xué)院建立的Novacem已經(jīng)引起了一些大建筑公司和投資機(jī)構(gòu)的注意，如Rio Tinto礦業(yè)、WSP集團(tuán)、Laing Orourke公司和節(jié)碳基金。
Novacem公司只是剛剛開始一個(gè)由政府技術(shù)戰(zhàn)略委員會(huì)支持建立的150萬(wàn)英鎊的試驗(yàn)工廠。
如果一切順利，Vlasopoulos 預(yù)計(jì)五年內(nèi)該款Novacem 水泥產(chǎn)品可以投入市場(chǎng)。

Engineers invent cement that can eat globe-warming CO2
Thanks to an innovation from British engineers, cement, a vast source of planet-warming carbon dioxide (CO2), could be transformed into a means of stripping the greenhouse gas from the atmosphere.
According to a report in the Guardian, Nikolaos Vlasopoulos, chief scientist at London-based Novacem, made the invention.
The new environment friendly formulation means the cement industry could change from being a significant emitter to a significant absorber of CO2, said Vlasopoulos.
Making the 2 billion tonnes of cement used globally every year pumps out 5 percent of the worlds CO2 emissions, which is more than the entire aviation industry.
In fact, the long-term trends are upwards. A recent report by the French bank Credit Agricole estimated that, by 2020, demand for cement will increase by 50 percent compared to today.
Making traditional cement results in greenhouse gas emissions from two sources: it requires intense heat, and so a lot of energy to heat up the ovens that cook the raw material, such as limestone. That then releases further CO2 as it burns.
But, until now, no one has found a large-scale way to tackle this fundamental problem.
Novacems cement, based on magnesium silicates, not only requires much less heating, it also absorbs large amounts of CO2 as it hardens, making it carbon negative.
According to Novacem, its product can absorb, over its lifecycle, around 0.6 tonnes of CO2 per tonne of cement.
Novacems cement, which has a patent pending on it, uses magnesium silicates that emit no CO2 when hearted. Its production process also runs at much lower temperatures, at around 650 degrees Celsius.
This leads to total CO2 emissions of up to 0.5 tonnes of CO2 per tonne of cement produced.
It has been estimated that the new cement has a vast potential market.
Set up by Vlasopoulos and his colleagues at Imperial College London, Novacem has already attracted the attention of major construction companies such as Rio Tinto Minerals, WSP Group and Laing ORourke, and investors including the Carbon Trust.
The company has just started a 1.5 million pounds project funded by the government-backed Technology Strategy Board to build a pilot plant.
If all goes well, Vlasopoulos expects to have Novacem products on the market within five years.
