Paper Title:
Study on Site Construction Technology of Four-Graded RCC
  Abstract

Tests on rolling technology of four-graded RCC were carried out on dam site and then recommended construction parameters of four-graded RCC was proposed, which aimed to provide technique support for application of four-graded RCC in hydropower projects. Results show that when water consumption is 71kg/m3 and VC value is 3s~5s of four-graded RCC, large aggregates are coated with mortar sufficiently and the mixture has good performance of being-rolled and anti-separation. Recommended parameters of four-graded RCC are as follows: 2 times without vibration+6 times with vibration+2 times without vibration for 0.4m-thick layer, 2 times without vibration+8 times with vibration+2 times without vibration for 0.5m-thick layer, with rolling exciting force 395kN and walking speed 1.0~1.5km/h. Then the relative compaction of four-graded RCC can reach or exceed 98.0%.
