A: Fineness (specific surface area) is determined using the Blaine air permeability method, as per ISO 6892. For Blast Furnace Slag Ore Powder, optimal values are 420–480 m²/kg.
Q3: What quality control tests are performed?
A: Key tests include laser particle size analysis, X-ray fluorescence spectrometry (XRF), compressive strength (EN 196-1), sulfate resistance (ASTM C1012), and loss on ignition. All batches traceable by QR code and digital logs.
Q4: Which standards or certifications do you hold?
A: ISO 9001 (Quality Management), EN 197-1, ASTM C989, and SGS/CE certification verify our compliance and product quality.
Q5: What is the lifetime or durability difference using Blast Furnace Slag Ore Powder?
A: Concrete containing >45% slag powder shows service life exceeding 100 years in marine and buried environments, with up to 3x chloride resistance versus standard OPC (verified by ASTM C1202 RCPT results).
Q6: What is the recommended installation or batching standard?
A: Adhere to ACI 211.1 guidelines for batching; recommend adjustment of water-binder and admixture dosages due to increased powder fineness. Full technical support provided.
Q7: What about aftersales and quality claims support?
