Strength development of ternary cements
Low-clinker ternary cements containing clinker, blastfurnace slag and calcined clay are becoming increasingly important in cement markets where decarbonisation is the key to sustainable construction. Central to the production of concrete for these construction projects is the strength development of ternary cements, which is the focus of a recent research project by VDZ. By Simone Elisabeth Sc...
ACCSESS for CCS projects
Carbon capture, utilisation and storage (CCUS) is an important pillar of HeidelbergCement’s carbon neutrality roadmap. As part of Project ACCSESS, the company will be the first to pilot CCUS technology in eastern Eur...
Aggregates go carbon negative
There is a consensus that, to reach net zero by 2050, the cement industry must embrace carbon capture, utilisation and storage (CCUS). This article looks at the potential of CCUS for the treatment of cement residues ...
Addressing AF myths
Existing misconceptions about the use of alternative fuels (AFs) continue to form a barrier to increased thermal substitution rates in cement plants. Specialist AF producer N+P addresses these myths and provides proc...
Rohožník White is green
White cement is used to create some of the greatest architectural landmarks that attract attention all over the globe. In Europe white cement is only produced in a few places, including at the Rohožník cement plant i...
Sludge co-processing progress and prospects
China has significant potential for the development of cement kiln co-processing technologies of municipal sludge and other solid wastes. In this article, a dry sludge disposal project at a cement plant in Guangdong,...
Buckets of flexibility
In the cement industry high-capacity bucket elevators are used to lift a wide range of bulk materials, including raw mix, limestone, coal, raw meal, clinker and cement. Gambarotta Gschwendt recently received an order...
Beyond primary measures
Under tightening emission legislation, it may be time to consider new technologies and products to remain in compliance. Denmark-based Umicore offers a variety of catalysts for the removal of NO x , NH 3 , dioxins, C...
Graphene’s future potential
Reducing carbon emissions in the cement industry is a top priority, but how to achieve that is the subject of considerable research and development. For First Graphene Ltd and Fosroc International, graphene shows gre...
LC3 in codes and standards
Reducing 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 imple...
Ensuring the quality of calcined clay cement
While calcined clays are fast becoming a sustainable alternative to reduce carbon emissions, ensuring the quality of calcined clay cement is key to gaining widespread market acceptance. By Prof Fernando Martirena-Her...
Asia Cement’s SWAP
The trend for longer bags in baghouses requires cement plants to review their bag cleaning systems. Gas filtration specialist CTP Team recently installed its advanced SWAP technology at Asia Cement’s Pukrang plant in...
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 ...
Taking the magic out of machine learning
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...
Influencers of strength
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 ...
Feeling the heat of mercury
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 mer...
