Alkali-activated materials

16 March 2021, Published under Cement News

While blastfurnace slag and metakaolin are known to produce a binder phase following alkali activation, the range of alkali-activated materials is wider than these two materials. This month Arthur Harrisson provides an overview of low-and high-calcium precursors that are subjected to alkali activation to produce binders. Figure 1: fly ash, a low-calcium AAM precursor Materials that arise as waste or a by-product from industrial processes other than Portland cement manufacture ha...

Lehigh Hanson partners with Fortera to reduce carbon emissions

15 March 2021, Published under Cement News

North America's Lehigh Hanson (HeidelbergCement) and Fortera Inc have announced a collaboration project to reduce emissions from Portland cement production. The two companies will work together to construct and operate a small commercial plant at Lehigh's cement facility in northern California. The plant will capture CO 2 from the kiln exhaust and convert it into a cementitious material. This can then be blended with Portland cement and used by ready-mix concrete producers as an SCM or us...

Cemex makes key EMEAA investments at the start of 2021

23 February 2021, Published under Cement News

Cemex has started 2021 by investing for growth and its climate action strategy in Europe, Middle East and Africa (EMEAA). It has made seven bolt-on investments that are aligned to its key priorities of climate action, sustainable construction and EBITDA growth, representing advances in fossil fuel reduction, lower-CO 2 products, circular economy, recycling and products that demonstrate life cycle CO 2 and energy consumption advantages for buildings. The investments include a new, low...

From WHRPG to EfW

09 November 2020, Published under Cement News

As cement plants search for ways to reduce their carbon footprint, waste heat recovery power generation (WHRPG) systems are becoming more popular. The use of biomass also provides potential as an energy-from-waste (EfW) solution to produce electrical power. Developments in WHRPG and biomass/EfW power generation systems are discussed below, including new technologies for energy saving and environmental load reduction. By Kawasaki Heavy Industries Ltd, Japan. Figure 1: flow of a waste h...

Cement sector pushes up Vietnam's CO2 emissions forecast for 2030

15 September 2020, Published under Cement News

Vietnam has submitted its forecast for CO 2 emissions by 2030 to the United Nations and has factored in the cement sector for the first time. Under the new plan the country only expects to cut its greenhouse gas emissions growth by nine per cent or nearly 84Mt of CO 2 by 2030 compared to its projections using 2014 as a baseline. Emissions are still expected to grow by 844Mt of CO 2 during that time. Vietnam is expanding the scope of the country’s climate plan to include emissions from in...

CEMBUREAU's Carbon Neutrality Roadmap to reduce CO2 to net zero by 2050

13 May 2020, Published under Cement News

CEMBUREAU's Carbon Neutrality Roadmap (CNR) looks at how the European cement industry can reduce its carbon emissions by 2050, and align with the objectives of the European Green Deal. It demonstrates that reaching net zero emissions along the cement and concrete value chain is achievable by 2050. Experts from the European cement industry have looked in detail at the role of key technologies in reducing emissions at each stage of the cement and concrete value chain. CO 2 emissions can inde...
