| Abstract: | The three recorded concrete core samples with length more than 10 m were obtained in the construction of Jin'anqiao RCC dam.The checks and tests show that:(a)sample appearance is smooth and dense,and the aggregate is evenly distributed;(b)the mechanical properties,ultimate tensile strength and durability meet the design requirements;and(c)the permeability rate gained by water pressure test is less than 1 Lu.The in-situ shear tests show that the interfaces(joints)of RCC lifts have a good bonding and meet the... |
