Roller Compacted Concrete Dam Compacted Thickness Increased Analytical Quality Assurance

Abstract

At present, roller compacted concrete (called RCC) technology has developed rapidly. So in order to make the RCC dam, RCC dam construction technologies have been further developed and accelerate its construction schedule. Many projects have begun to regulate the conduct of RCC which has been breakthrough in compaction layer thickness 30cm field test, which by increasing RCC compaction layer thickness. Many experiments construction proved that: RCC roller compacted concrete layer thickness increasing is feasible. However the increasing compaction thickness, the deck construction process and the successful completion of the jelling time of concrete is the key factors to ensure quality of the dam. It is the big prerequisite for completion. We will integrate field test to the quality control of the dam after the compacted layer thickness is increased.
