During the compiling process, this Standard not only absorbssome relevant contents in the similar domestic and internationalstandards that are suitable for the application of hydraulic concrete inChina, but also emphasizes the characteristics of mass hydraulicconcrete. With the advancement of hydraulic concrete technology, theuse of admixtures and additives has become more and more popular,and widespread attentions have been paid to the durability of concrete.Therefore, changes of stipulations in this Standard are more focusedon the use of admixtures, and additives and the durability of concrete.
