RoboAggregates are obtained by crushing parent rock through a three-stage configuration of a Jaw Crusher, a Cone Crusher and a Vertical Shaft Impactor (VSI), giving cubical particles with consistent gradation and better bonding at the aggregate-cement paste interface. They are used as a base material under foundations, roads, rail roads and landfills, and with RoboSand to produce PCC, RCC, normal and high strength concrete, and speciality concretes such as self-compacting and pre-stressed concrete. Both the 20 mm and 10 mm grades conform to IS 383 - Graded Aggregates.

Key features

• Good quarry source
• Perfect gradation
• Consistent quality standards
• Assured quantities
• Cubical particle shape - high compressive strength of concrete
• Internal gradation per IS 383 - reduction in voids increases workability
• Surface texture - reduction in moisture absorption / lower water cement ratio
• Greater durability - longevity of structure / higher resistance to an aggressive environment
• Zero impurities (marine and organic) - reduction in wastage and increase in economic value
• Better bonding at the interface of aggregates with cement paste

Applications

• Base material under foundations
• Base material under roads and rail roads
• Base material under landfills
• Under culverts, bridges, driveways, storm drains and transformer yards (stable foundation to prevent differential settling)
• New infrastructure work and maintenance of existing infrastructure
• PCC and RCC
• Normal strength and high strength concrete
• Self-compacting concrete
• Pre-stressed concrete
