The low-carbon cement bet

10 May 2022, Published under Cement News

Cementos Argos has developed a low-carbon cement using alkaline activation technology to formulate hybrid cements. This type of green cement allows the increased use of supplementary cementitious materials activated with additives which significantly reduces the clinker content and, therefore, CO 2 emissions. By MF Díaz-Burbano, Cementos Argos, Colombia. To activate the SCM correctly, additives are fed into the process using an accurate dosage system Supplementary cementitio...

Taking the magic out of machine learning

20 April 2022, Published under Cement News

Artificial intelligence (AI) and its subcomponent machine learning (ML) are almost everywhere in industrial processes, and cement manufacturing is no exception. 1,2 Despite the common use of these terms, how a model is built and implemented remains a mystery to many. Holcim Innovation Center demystifies the process by stepping through a machine learning project.  By Louise Harding and Xavier Cieren, Holcim Innovation Center, France.

Over the years several factors that influence the strength of cement have been determined. These include mineralogy, chemistry, microstructure and process.   Figure 1: central irregular alite growth with many inclusions surrounded by clearer alite growth The various influences on the strengths achieved by Portland cements has been the subject of a number of research projects in the laboratory as well as analyses of industrially-produced materials over the years. A useful method ...

Feeling the heat of mercury

21 February 2022, Published under Cement News

Cement kiln operators, particularly in cases of co-incineration, may feel the heat when considering upcoming government regulations regarding mercury emissions. Therefore, it is recommended to invest in upgrading mercury monitoring systems if existing ones use out-of-date technology that no longer complies with mercury monitoring standards. By Gasmet, Finland. Continuous mercury monitoring systems help cement plants avoid over-the-limit emissions In an effort to decrease fossil ...

Changing colour

30 November 2021, Published under Cement News

Brown or yellow colours in the clinker core are indicative of unfavourable burning conditions such as reducing conditions in the kiln, according to specialists. At Tehran Cement Co, researchers have carried out a laboratory study into the effect of colour changes in the clinker core on the technical characteristics of cement. By Ali Akbar Kafash Bazari, Tehran Cement R&D Center, Iran, and Mohsen Tadayon, Iran Concrete Association, Iran. Figure 1: microscopic image of clinker with redu...

VRM audits and optimisation

16 November 2021, Published under Cement News

The increasing use of vertical roller mills (VRMs) in the production of cement to reduce power consumption and CO 2 emissions has resulted in an increasing need for VRM  optimisation. As cement producers look to protect profits as well as their environmental reputation, a process audit can identify the root causes of issues to help plan for improvements in power consumption and performance.
