Admixtures for Concrete - Memphis

admixtures usually retard the setting time of concrete by one to three hours (Fig. 6-5). Some water-reducing admix-tures may also entrain some air in concrete. Lignin-based admixtures can increase air contents by 1 to 2 percentage points. Concretes with water reducers generally have good air retention (Table 6-2).
