Guide Specification for Construction of Roller-Compacted
Guide Specification for Construction of Roller-Compacted Concrete Pavements 1. General Provisions 1.1 Description.Roller-Compacted Concrete (RCC) shall consist of aggregate, portland cement, possibly other supplementary cementing materials (fly ash, slag and silica fume) and water. RCC shall be propor-tioned, mixed, placed, compacted and cured Improving feeding powder distribution to the compaction ,Roller compaction is a continuous dry granulation process, which is widely used in pharmaceutical and food industries. Moisture sensitive powders are able to be granulated, as there is no need to add liquid binder to produce agglomerates.
