DL/T 5151-2001水工混凝土砂石骨料试验规程（英文版）

　　revised for the second time，to meet the need of the development of hydropower and water conservancy construction in China，and to coordinate with the development of standards of same categories at home and abroad．The original code was amended，supplemented and divided into Test Code for Hydraulic Concrete．Test Code for Aggregates of Hy draulic Concrete and Analytical Test Code for Water Quality of Hydraulic Concrete．The original Test Code for Hydraulic Concrete SD 105-1982 is replaced by the three newly published codes，with the original Chapter 3，“Aggregates"replaced by Test Code for Aggregates of Hydraulic Concrete DL/T 5151-2001.
