Project-Specific Sourcing
Basalt Fiber for Cementitious Systems
Chopped basalt fiber sourcing for concrete, mortar or shotcrete systems where alkali durability, sizing, dispersion and the intended cementitious process are documented.
Project-Specific Sourcing
Material screening
Basalt source and sizing must be verified
Basalt fiber is produced from melted basalt rock, but product durability in a cementitious alkaline environment depends on composition, manufacturing and surface sizing. UCGP requires source-specific evidence.
Fiber formChopped strand, filament or another confirmed form.
DimensionsLength, filament diameter and bundle integrity.
SizingCement-compatible surface treatment and dispersion behavior.
DurabilityAlkali-resistance and aging evidence for the intended matrix.
ProcessPremix, shotcrete, mortar or other production method.
AcceptanceProject-specific mechanical and durability test plan.
Do not generalize
Natural origin does not prove concrete durability
A commercial review should identify the exact manufacturer and technical data before any crack-control, strength or durability statement is used for design.
Mix compatibilityCement chemistry, supplementary materials and admixtures.
HandlingBundle opening, dust, addition sequence and dispersion.
ApplicationMortar, precast, shotcrete or another defined cementitious system.
EvidenceSource data, test method, sample trial and approval responsibility.
