前言

As one of the basic codes in the standard system of water resourcesand hydropower construction，the Test Code for Aggregates of Hydraulic Concrete is voluntary standard．The related contents in this Code are originated from SD 105一1982．Test Code for Hydraulic Concrete．According to the requirement of management of the electric power industry standards(Document No.40[1996]) issued by the former Ministry of Power Industry in 1996，the Test Code for Hydraulic Concrete SD 105-1982 was 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．TestCodeforAggregatesofHydraulicConcreteDL/T5151——2001，including 34 test methods，gives prominence to the aggregate quality，especially the aggregate soundness required by hydraulic mass concrete．A lot of supplement was done for the alkali aggregate reactivity test methods．
