对《水工混凝土配合比设计规程》(DL/T 5330-2005)中采用饱和面干表观密度进行配合比设计计算骨料用量及《水工混凝土砂石骨料试验规程》(DL/T 5154-2014)中饱和面干表观密度试验方法提出了异议,认为《水工混凝土配合比设计规程》中计算单方混凝土中的饱和面干骨料用量应采用骨料的表干密度;《水工混凝土砂石骨料试验规程》中骨料饱和面干表观密度的试验方法实际是骨料表干密度的试验方法.
對《水工混凝土配閤比設計規程》(DL/T 5330-2005)中採用飽和麵榦錶觀密度進行配閤比設計計算骨料用量及《水工混凝土砂石骨料試驗規程》(DL/T 5154-2014)中飽和麵榦錶觀密度試驗方法提齣瞭異議,認為《水工混凝土配閤比設計規程》中計算單方混凝土中的飽和麵榦骨料用量應採用骨料的錶榦密度;《水工混凝土砂石骨料試驗規程》中骨料飽和麵榦錶觀密度的試驗方法實際是骨料錶榦密度的試驗方法.

In the "Code for Mix Design of Hydraulic Concrete (DL/T 5330-2005)", the saturated dry-surface appar-ent density of the concrete aggregate is used to calculate the aggregate quantity.Also, a testing method of the saturated dry-surface apparent density is provided in the "Test Code for Aggregate of Hydraulic Concrete (DL/T 5154-2014)". In this paper , it however suggests that the saturated dry-surface aggregate quantity should be calculated by the dry-sur-face density.And, the testing method provided in the "Test Code for Aggregate of Hydraulic Concrete (DL/T 5154-2014)" is actually for the dry-surface density of the aggregate.
