Strength predictions
A prediction of strength in concrete can be made through a range of methods and with numerous variables. To facilitate this, Arthur Harrisson examines the key factors that control strength development in concrete. Figure 1: cement 28-day strengths Various methods have been developed to predict the strength that a concrete may reach with a particular combination of cement, suppleme...
Separation revisited
Even a high-performing system can be made more efficient, as global plant engineering and construction specialist thyssenkrupp Industrial Solutions demonstrates with the sepol® separator. Thanks to technical optimisa...
Self-healing concrete
The formation of cracks in concrete is a common occurrence and in many cases is not regarded as a major issue. However, in some circumstances they may pose a threat to a concrete structure if its purpose is to preven...
As white as white
Producing white clinker and cement requires the right raw materials and mix, the right fuel and optimal plant process conditions. JK Cement Works Fujairah explains what action it takes to keep its white clinker and c...
Analysing raw mix control
The monitoring and control of the chemical composition of the raw meal is a key function at a cement plant, not only in terms of delivering a high-quality end product, but also for avoiding the negative impacts on a ...
Are you ready2grind?
Flexible deployment of grinding plants with rapid installation and commissioning enables cement companies to improve their competitive edge as market requirements change and different products are needed. To meet thi...
Flexible grinding
Modular grinding plants provide cement producers with greater flexibility when rapidly deploying assets in or near fast-expanding markets to benefit from their first-mover status. By Moisés Rodríguez Núñez and Eduard...
Industry 4.0: press ‘Start’
The application of Industry 4.0 concepts and its suite of buzzwords such as ‘IoT’, ‘Digital Transformation’ and ‘Big Data’ presents challenges to a range of industries, including cement. What can cement producers exp...
Into the future
There is no way we can imagine the world without cement and concrete. From 30 years ago, when International Cement Review was first published, until today, cement production on the planet has quadrupled. Depending on...
Cement logistics: the end of the beginning
In 1988 Commodore still sold over one million units of its C64, nicknamed “The Model T of personal computers”, and commercial logistics software was in its infancy. We have come a long way and our industry is now sta...
Materials & quality: 30 years on
The development of new cement types and demands on fuels as well as changes in process requirements have led to key changes in cement production over the last three decades. New raw materials and alternative fuels ha...
Benchmarking ready-mix logistics performance
Algorithms and computer hardware have revolutionised the performance of logistics planning tools in many regions around the world. However, market conditions and business modalities may vary from region to region, so...
Cement by sea
Moving cement by sea is a difficult business, often requiring dedicated vessels fitted with specialist equipment. Shipowners and operators also have to manage freight rate fluctuations, new environmental regulatio...
Injecting new life in NOx control
The aqueous ammonia (NH 3 ) injection system for nitrogen oxide (NO x ) emission reductions at a cement plant in Florida, USA, provided limited ability for flow downturn and material usage efficiency. A new injection...
Alternative fuels and clinker crystal characteristics
Arthur Harrisson examines the effect of alternative fuel use on the characteristics of crystals present in clinker. Figure 1: difference in alite quantity measured by microscopy and the Bogue cal...
Keeping your cool
Yanbu Cement Co looks at the importance of optimising cooler operation in managing a cement plant’s energy consumption and protecting downstream equipment. By Amr Nader, Yanbu Cement Co, Saudi Arabia. Figure 1...
