Gypsum and lignite test method for aggregate
DETERMINATION OF LIGHT WEIGHT PIECES (COAL & LIGNITE) IN
Jun 19, 2014· The percentage of light weight pieces (coal & lignite) in the aggregate is reported to the nearest 0.1 percent. Precautions. Chemicals used in this test are highly toxic, both by absorption through the skin and by inhalation. While testing, use a hood and care shall be taken to avoid contact with the skin or inhalation of fumes. ReferenceStandard Test Methods for Physical Testing of Gypsum,Abstract. These test methods cover the physical testing of gypsum, gypsum plasters, and gypsum concrete. Test methods are detailed for the following: precautions for physical tests, reagents and materials, free water, fineness, normal consistency of gypsum plaster and gypsum concrete, setting time, setting time (temperature rise method), compressive strength, and density.
