Sand Equivalent Value Of Fine Aggregate In Concrete . If the Sand Equivalent value is less than 60 and greater than or equal to 50 the sand shall be considered nonharmful and is accepted provided that the Methylene Blue value is less than or equal to SE 10 gkg IA 24 FINE AGGREGATE FOR CONCRETE AND MORTAR AB 1 Fine aggregate consist of natural clean sand stone screenings or a
aggregates—sand, gravel, crushed stone, and aircooled blastfurnace slag—produce freshly mixed normalweight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 53) are used to produce structural lightweight concrete with a freshly mixed density
· Hi, What is the difference between sand equivalent test values and sa simple silt content test? I mean when you finish a SE test, specs say that min 75% SE value is accepatable, which means max 25% of clay/silt content is acceptable limit for sand used in structural concrete!
