Ecocem announces total CO2 emissions saving20 December 2018, Published under Cement NewsIreland’s Ecocem, Europe’s largest independent specialist producer of low-carbon cement, has announced that its efforts over 16 years to encourage replacing high-carbon cement with low-carbon cement has resulted in a saving of 10Mt of carbon emissions, according to a press release. The company’s ground-granulated blastfurnace slag (GGBS) cement has a carbon footprint approximately 95 per cent lower than traditional cement at 32kg/t, and can be used as a one-to-one replacement in formulating... |
Durability of composite cements with calcined clay13 December 2018, Published under Cement NewsComposite cements are clinker efficient and play an important role in reducing CO 2 emissions from cement manufacturing. To assure their correct application in concrete, their performance in concrete has to be demonstrated, especially with regard to durability under different concrete exposure conditions. As part of a long-term research programme, such cements made of different calcined clays were used in conventional concrete mixtures and tested for their resistance to carbonation, chlorid... |

China's carbon trading passes CNY6bn26 November 2018, Published under Cement NewsChina's seven pilot carbon trading schemes reached CNY6bn (US$863.9m) at the end of October, rising from CNY4.7bn at the end of 2017, reported the Ministry of Ecology and Environment. China's pilot CO 2 trading schemes cover the cities of Beijing, Tianjan, Shanghai, Chongqing and Shenzhen, and the provinces of Guangdong and Hebei. The schemes were introduced in 2013 and include the cement and other carbon-emitting industries. A total of 250Mt of carbon dioxide changed hands on the exchang... |
The European Climate Foundation releases CO2 emissions report01 November 2018, Published under Cement NewsThere is a significant saving potential of up to 80 per cent of CO 2 emissions in the cement sector by making use of efficiency measures along the whole value chain, without carbon capture and storage (CCS) technologies. These CO 2 savings could be achieved for a relatively-low financial cost and even with financial savings in some cases. If combining this with CCS, a-close-to carbon-neutral cement and concrete sector is feasible by 2050. This is the main finding of “ A sustainable futur... |
Into the future19 July 2018, Published under Cement NewsThere is no way we can imagine the world without cement and concrete. From 30 years ago, when International Cement Review was first published, until today, cement production on the planet has quadrupled. Depending on regional developments this volume may more or less stabilise going forward or even exhibit further growth. In any case, the cement industry will continue to lower the CO 2 footprint of cement and concrete. By Dr Martin Schneider, VDZ, Germany. Figure 1: cements containin... |
New report predicts rising pressure on producers to cut emissions19 July 2018, Published under Cement NewsA new report by Moody’s Investors Service suggests that the cement industry could face demand growth of 12-23 per cent by 2050, resulting in a challenge to meet this demand and still make large-scale carbon emissions cuts. "Regulation of the industry is likely to increase and a rise in carbon prices under the EU-ETS combined with a reduction in allowances to the cement sector would have a significant impact on the cash flow of EU cement producers, in the event cement makers were unable to p... |
Bringing on the substitutes18 July 2018, Published under Cement NewsAs part of its drive to reduce its CO 2 emissions, Votorantim Cimentos is using a range of clinker substitutes to lower its clinker-to-cement ratio. As a result, around 86 per cent of its product portfolio in Brazil has a reduced carbon footprint, lowering its impact on the environment. By Silvia R S S Vieira, Votorantim Cimentos, Brazil. The use of substitute materials such as acidic slags (pictured: maganese slag) and calcined clay is key to reducing a cement plant’s carbon foot... |
LC3: a promising alternative16 July 2018, Published under Cement NewsThe drive for a sustainable construction industry has triggered the development of a range of building materials that serve as sustainable alternatives to Portland cement. The development of limestone calcined clay cements (LC 3 ) offers a glimpse into the future of building materials.
