Lightweight Concrete Aggregates
Alkemy Produces 3 types of Lightweight aggregate from waste:
Expandable Lightweight Aggregate
High Strength Lightweight Aggregate
Masonry Concrete | Precast Concrete | Structural Concrete | Geo-fill
Fine Fraction: .5-2mm or 2-4mm
Production of concrete and heat resistant fittings.
Medium Fraction: 4-8mm
Production of precast concrete (structural floor tiles, wall tiles, garden hollow tiles, etc.)
Production of structural concrete.
Coarse Fraction: 6-12mm
Production of no-fines concrete, light blocks, concrete planks, and heat-insulating screed on floors.
Backfills in sheeting and retaining walls.
Structural lightweight concrete: weight reduction, less reinforcing, enhanced durability.
Precast lightweight concrete: weight reduction, transport savings, larger units, design flexibility.
Masonry lightweight concrete: weight reduction and quick drying.
Geo-fill / Land drainage: reduced HS pressure, transport costs, chemical resistance, and hydraulic conductivity.
Alkemy's lightweight concrete aggregates have been independently tested and certified with industry standard accreditations, including:
ASTM certification US: EPA TCLP EU: End-of-Waste Standards
BS/EN certification LEED certification
Our aggregates are produced at a lower cost than the mined rock used today and can help your business gain a competitive foothold in the construction industry of the future. Contact us to learn more.
