Projects, Products and Problem Solutions

Building Materials Engineering Day, Essen/Germany (27.03.2009)

Lecturers und host during the Dyckerhoff Building Materials Engineering Day in Essen 2009

Actually innovative special cements and advanced high-performance concretes as well as projects, products and problem solutions involved should be in the focus of the Dyckerhoff Building Materials Engineering Day 2009. Due to the current economic development, also the impact of the economic crisis on the cement industry was on the agenda in Essen. Above all, the decline in the steel industry led to a strongly reduced offer of granulated blastfurnace slag, which is needed for the production of CEM II cements.

A wide range of topics all about the building material concrete and a...
