Is roller-compacted concrete as strong as conventional formed concrete when used in an industrial application like a compost facility pavement?
Yes, it is. In a concrete mixture, portland cement chemically reacts with water to bind the aggregate and sand into a solid mass. A key determining factor to concrete strength is water to cement ratio. Low water cement ratio concretes generally have higher strengths. In the placement of conventional concrete pavement, formwork is used to create the area and thickness of the pavement design and a concrete mixture is cast (“poured”) into the forms and finished. Concrete mix designs used for conventional formed concrete have excess “water of convenience” to lubricate the mixture making it easier to place and finish within the formwork. Assuming no water reducing admixtures are used, mix designs have lower water cement ratios than conventional concrete. They have enough water to react with the cement but very little extra. Whereas internal vibration is typically used to consolidate conventional concrete, the dry consistency of RCC requires the use of external compaction methods in the form
