摘要

CementHardwoodAn additive to be added to the composition containing the sleeping agent andThe concentration of aluminum ions in the liquid phase obtained by solid-liquid separation of the hard-containing composition obtained after 30 minutes after the addition of the hard agent to the composition at 5With respect to the concentration of aluminum ions in the liquid phase obtained by solid-liquid separation of the non additive composition obtained in the composition at 5It is 1.1 times or more, and it is a hardship for rapid concrete concrete shipment type rapid type concrete.
