RCC is batched and mixed onsite using a portable mixing plant. Occasionally, one or more aggregates are obtained on or near the site and graded to conform to the specified aggregate gradation. It is more common to purchase aggregates from an aggregate supplier who delivers and stockpiles them near the batching and mixing plant. Portland cement (hereafter referred to as “cement”) and a pozzolan such as fly ash are imported and stored onsite near the batching and mixing plant. After batching and mixing, the RCC mixture is transported, placed, and compacted using earthfill and rockfill-type construction equipment. Ideal RCC projects will involve large placement areas, few or no reinforcement, and no embedded items, such as pipes.
