White Fused Alumina (White Corundum)FEPA F80 for use in laboratory abrasion testing of concrete products
White Fused Alumina (White Corundum) FEPA F80 is a standardized high-purity abrasive grain specially produced for laboratory abrasion resistance tests of concrete and cementitious products. Manufactured by melting high-grade alumina in electric arc furnaces above 2000°C, then crushed, screened and graded strictly according to FEPA standard, this F80 grade features sharp angular grain shape, Mohs 9 hardness and consistent particle size distribution.
Its stable physical properties and low impurity content ensure repeatable and reliable test results, eliminating data deviation caused by inconsistent abrasive media. The grains maintain steady cutting action during cyclic abrasion tests, making it ideal to evaluate the wear resistance of concrete slabs, pavers and precast concrete components.
We implement rigorous batch inspection for chemical composition, grain size and particle morphology. Every lot comes with inspection certificates to satisfy laboratory quality control requirements. This FEPA F80 white corundum is the preferred reference abrasive for concrete material research institutes and construction material testing labs. Custom packaging and technical data sheets are available upon request.
