Dummy Roller Compacted Concrete Designed for minimal water content (slump 0–1 cm) enabling placement and compaction without forms or mechanical vibration, Dense low-permeability matrix resists freeze–thaw, abrasion, and heavy vehicular loading—ideal for pavements and industrial yards, Placed in continuous lifts (150–200 mm thick) and compacted by rollers allowing large-area paving at high production rates, Heavy-duty pavements Industrial flooring, asphalt overlays

Key Features and Applications
Zero to Very Low SlumpDesigned for minimal water content (slump 0–1 cm), enabling placement and compaction without forms or mechanical vibration.
High DurabilityDense, low-permeability matrix resists freeze–thaw, abrasion, and heavy vehicular loading—ideal for pavements and industrial yards.
Rapid ConstructionPlaced in continuous lifts (150–200 mm thick) and compacted by rollers, allowing large-area paving at high production rates.
Versatile ApplicationsHeavy-duty pavements, Industrial flooring, asphalt overlays
Technical Specifications
Dry Density (In-Place)2,300–2,400 kg/m³
Aggregate GradationWell-graded, gap-graded blend of crushed stone and gravel
Cement Content250–350 kg/m³
Water–Cement Ratio0.30–0.40
Delivery & Placement Options
Bulk Ready-Mix DeliveryBatched at central plant with strict control of water and aggregate moisture; discharged directly into a hopper/conveyor for placement.
Compaction by RollersSmooth-drum static rollers, Vibratory rollers
Slip-Form or Static Paving MachinesEquipment spreads RCC in uniform lifts; slip-form pavers create a continuous mat, while static screeds require over-compaction.
