Forschungsergebnisse: Einfluss der Verringerung von Schmelzpunkt und Viskosität der Klinkerschmelze durch Aschen alternativer Brennstoffe auf Sinterreaktionen und Coatingbildung

Available in German

Ziel des Forschungsvorhabens war es, den Einfluss von Nebenoxiden aus Brennstoffaschen auf die Bildungstemperaturen der Klinkerschmelze und auf die damit verbundene Klinkermineralogie herauszuarbeiten. Ebenso sollten die Auswirkungen der verringerten Prozesstemperatur und der veränderten Eigenschaften der Klinkerschmelze auf die notwendige Bildung von Coatingschichten sowie die Feuerfestkorrosion und damit auf die Haltbarkeit der feuerfesten Zustellung in der Sinterzone des Drehrohrofens aufgeklärt werden.

Current

Durability of concretes with clinker efficient cements under modified concrete technological conditions

The current research project aims to determine if CEM II/C-cements can be used in some exposure classes (XC1-4, XF1) according to DIN 1045 2 under modified technological conditions of the concrete (reduced water-cement ratio, increased minimum strength class) without additional requirements.

Current

Interactions of accelerating admixtures and clinker-efficient cements with several main constituents to improve the early compressive strength of concrete

The acceptance of resource-efficient cements with significantly reduced specific CO₂ emissions is still too low in construction practice. The main reason for this is that early strength is not high enough for economical production processes and also competitive construction with concrete. Accelerating admixtures can improve the early strength of concrete. The research project investigates interactions between concrete admixtures that accelerate the strength development and cements with several main constituents.

Seminar

Wear of Refractory Materials

The refractory lining of a cement plant is subject to wear, which can be typical to abnormal depending on the process conditions. A premature wear of the refractory lining usually results in an unexpected loss of production, which is associated with high costs. In order to be able to better assess the reasons for the wear that has occurred, the course gives an overview of the types of wear in the cement plant and their interpretation. In addition, details are shown how the wear behaviour of the refractory lining in the cement plant changes as a result of the use of alternative fuels.

Seminar

Process Technology of Cement Production (In-Class Training)

This In-Class Training consists of two modules: "Grinding Technology and Raw Material Preparation" (Module 1) as well as "Clinker Production and Material Technology" (Module 2). Each module has a duration of one week. The course gives a deep insight into cement production technology, covering topics from quarry operation to cement grinding.

Seminar

Installation of Refractory Materials

For good lifetimes of the refractory materials in the clinker production line, a faultless installation is an important prerequisite. Even though the installation is carried out in most companies by external companies, supervision should be done by trained employees. This seminar should help the participants to be able to better evaluate the refractory installation and thereby recognise deficits at an early stage.

Congress

International­ VDZ Congress 2018

Climate protection and digitisation are key challenges for the cement industry: More than 600 representatives from the international cement industry and associated suppliers, as well as from scientific and research institutes around the world, gathered at the International VDZ Congress 2018 in Duesseldorf at the end of September. Steeped in tradition, the VDZ Congress is one of the world's most important events in the industry. The 40 talks held at this year's congress focused on particularly pressing topics such as climate protection and digitisation. The participants also discussed current technical challenges and the general situation with regard to cement production. A further highlight was an evening ceremony at which the winners of the VDZ Industrial Safety Prize 2017 received their awards.
