A new test method using moisture rate to represent workability indicators of dry-hard mixture is introduced in order to test the control indicators of VC value in the construction of roller compacted concrete rapidly. In view of the complexity of the impact of proportional difference on VC value and moisture rate, this paper carries out field tests of roller compacted concrete in Guoduo hydropower station of Tibet. A simplified linear quantitative model formula of VC value and moisture rate at the construction site is established based on determined aggregate grading, admixture, additive type and the amount of admixture of roller compacted concrete mixture, providing conditions for the rapid and accurate measurement of construction quality indicators of roller compacted concrete.
Key words: roller compacted concrete / VC value / moisture rate / test method
