The low-carbon cement bet

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, ...
