LC3 in codes and standards11 July 2022, Published under Cement NewsReducing the carbon footprint of the concrete industry is a priority in the face of global warming. Limestone calcined clay cements (LC 3 ) provide one of the best options to reduce CO 2 emissions. For optimal implementation, but also to facilitate other low CO 2 solutions, standards that regulate the cement and concrete sector need be adapted quickly. In this article, two main standardisation regions are reviewed in light of the feasibility of adoption and deployment of LC 3 technology. ... |

The low-carbon cement bet10 May 2022, Published under Cement NewsCementos 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 learning20 April 2022, Published under Cement NewsArtificial 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. Figure 1: machine learning implementation steps ... |
