The October 2018 issue of Global Cement Magazine contains all of the latest global cement news, plus technical and feature articles on gears, emissions, quarrying and dynamic cement pricing. There's also an in-depth look at the latest in the west African cement sector (15 countries) and reviews from the FICEM Technical Congress 2018 in Panama and the RWM Exhibition in the UK. There is also a strong 'concrete flavour' as we analyse the Top 25 global concrete producers by production volumes. This is, we believe, the first time that anyone has published such a list. There is also a look at how cement activation can rejuvenate cement that has lost efficiency through prolonged storage, offering concrete manufacturers the opportunity to use less cement while still attaining high strength.
