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 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 standardisati...
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...
Durable dampers
To guarantee the regular operation of a tertiary air duct (TAD) system, importance should be placed on damper performance. Topnewer’s prefabricated damper with a framework made of non-metal ceramics has been develope...
Smart conveying
To get the maximum out of maintenance, proactive and predictive approaches have proven to increase the overall efficiency of plant equipment. The PREMAS® 4.0 predictive maintenance solution, developed by AUMUND for c...
Inline and offline oil filtration
Proper oil filtration can reduce downtime and increase equipment reliability. Combining inline and offline filtration technologies can ensure optimum lubricant cleanliness, and lead to an increase in component and oi...
Changing colour
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 lab...
VRM audits and optimisation
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 pro...
Radiometry: advancing cement process control
In the challenging conditions of a cement plant, traditional process control methods are not always suitable. Radiometric process control provides a non-contact and non-intrusive technique to carry out continuous lev...
The cement industry’s energy challenge
With global cement demand expected to rise by as much as a quarter by 2050, the industry faces a range of challenges to produce in a more sustainable way. One aspect is to reduce its energy input to reflect tighter e...
Sample preparation meets digitisation
Process sample analysis is increasingly important in the cement industry. The preparation of samples is key to ensure rigorous quality control of a range of materials, from raw materials to the finished products. An ...
Measuring systems for CCUS
Following the Paris climate agreement (2015), the decarbonisation of the energy and industrial sectors is becoming increasingly important. One of the most significant measures to achieve the climate targets is to red...
