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.

以某水利工程倒虹吸管身段混凝土的配合比設(shè)計(jì)為例,探討了絕對(duì)體積法在水工混凝土配合比設(shè)計(jì)中的應(yīng)用。通過(guò)實(shí)例可以看出,采用絕對(duì)體積法進(jìn)行水工混凝土配合比設(shè)計(jì)過(guò)程相對(duì)簡(jiǎn)單,無(wú)需含水量測(cè)定及換算,易于操作。且經(jīng)過(guò)檢測(cè)證明,該方法配比出的混凝土各項(xiàng)指標(biāo)均符合設(shè)計(jì)要求。
