Testing of light weight aggregates (LWA) materials

Abstract

LWA materials in the size fractions 0.8-1.6 mm and 2-4 mm from 8 European counrties (Portugal, Denmark, Estonia, Sweden, Finland, Spain, Germany, Norway) were analysed for Mohr hardness, sink velocity, specific surface, acid loss, pH, P sorption capacity, chemical composition and hydraulic conductivity using the procedure described in the manual "Test methods for Filtralite". Product specifications for each country are enclosed.
