New additions to concrete
Effective alternatives for precast concretes –
Problem statement
Precast concretes are subject to demanding materials-related parameter requirements as well as to commercial and ecological aspects. The importance of these factors will further increase in future years as sustainability issues become increasingly relevant. Means for making greater use of efficient additions to concrete, together with substitution of cement clinker, are therefore of special interest. In recent years, around 8.5 million metric tons of cement (corresponding to approx. 30 % of overall cement consumption) went into the manufacture of precast concrete elements,...
