Dec 01, 2014· The weighted average loss cannot be greater than 10% when sodium sulfate is used or 15% when magnesium sulfate is Course Aggregate. According to ASTM C33 coarse aggregate consists of gravel, crushed gravel, crushed stone, aircooled blast furnace slag, crushed hydrauliccement concrete, or a combination.
Bulk specific gravity and absorption are based on a 24 ± 4h soaking time for the rock specimens tested. This test is appropriate for breakwater stone, armor stone, riprap, and gabion sized rock materials. The use of reclaimed concrete and other materials is beyond the scope of this test method.
Specific gravity is a mean to decide the suitability of the aggregate. Low specific gravity generally indicates porous, weak and absorptive materials, whereas high specific gravity indicates materials of good quality. Specific gravity of major aggregates falls within the range of to
Specific Gravity Absorption of Fine Aggregate (Mold Tamper Set Only) The metal tamper is 340g () with a 1in (25mm) face. SG2 Jar and Top includes a 1qt () threaded glass jar and a brass screwon top with rubber gasket that tapers to a () pour hole. The SGA8 Flask Adapter Set is required if the SG2 is used with the SGA5R Rice Shaker.
Specific Gravity and Water Absorption Tests on . #; Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is the measure of strength or quality of the specific material. Aggregates having low specific gravity are generally weaker than those with higher specific gravity values.
