In the paper, various methods of CNT (carbon nanotubes) injection into cement composites are studied. Modified slurry mix is studied on setting time, heat emission development and chemical shrinkage. Physical and mechanical properties of the slurries modified with CNT and superplasticizer are observed.
Due to the compact design and material transportation system of vertical roller mills (VRM), some important streams (total mill feed and discharge, dynamic separator feed and reject) remain in the mill casing. This situation leads to sampling problems around the equipment. This paper discusses a new simple sampling technique used for VRM in order to evaluate the performance of grinding and classification ...
Increasingly stringent political demands are being imposed on the energy productivity of the industry. In a plant-specific investigation, the savings...
Lafarge-Holcim will have the largest cement capacity of any of the cement producers in the Americas after their merger and sale of assets to CRH. In the following review we will discuss the implications of the merger, profile the major cement rivals in this region and look at the latest market developments in the major markets of the USA, Brazil and Mexico.
On 04.10.2014 the entire Leube workforce had cause for celebration. This day marked a new record for the company’s lime works in Golling, 20 km south of Salzburg/Austria: seven years of operation without a single accident – that means 2555 injury-free working days ...
Bags made of polyethylene (PE) are suited for many requirements, and are used for transportation and sales of many consumer goods. Yet, who would have imagined some years ago that powder-type products could also be filled into compact and weatherproof PE bags in an environment-friendly process? ZKG International had the opportunity to visit HAVER & BOECKER at the company’s headquarters in Oelde/Germany ...
More than 160 delegates from 22 countries took part in the annual General Assembly and Information Exchange Forum of the International Lime Association (ILA), which was held on 08.-10.10.2014 at the Pan Pacific Hotel in Vancouver/Canada. ...
Quick reaction to changing demand and changing short-term fuel or raw-material costs is the most decisive factor to a profitable plant operation in the modern cement industry. However, a production process involving deep pits, bunkers or bins demands the construction of massive foundations and a geography, where it is possible to dig deep down.
The Beumer Group rigorously gears the development of its equipment and systems towards providing customers with single-source, sustainable solutions for all their applications. To control, coordinate and visually represent ...
Martin Engineering from Neponset, IL/USA, a leading manufacturer in bulk material handling technology has introduced two conveyor system components designed to mitigate expensive spillage and belt wear issues at material transfer points.
At the beginning of 2015, the German Construction Chemistry Industry Association opened its own office in Brussels. Acting as a representative there...
