Zusammenfassung:Additive compsns. for maintaining mortar properties in fresh state (workability, use, reduced segregation) similar to that of mortar with additives is superior to that with lime. The additive comprises 0.8-5 wt.pts. nonylphenolethoxylate with 8-40 moles ethylene oxide, 1.5-6 wt. pts. hydroxyethylcellulose and a viscosity of 15-150 cp. and a concn. of 2% and 20-50 pts. water. The additive is introduced into a mortar press at 2-6.5 dm3/lm3 for mortar cpds. for building and roughcast.
