Summary This standard applies to the determination of the apparent density of the rock. Depending on the density of the rock refers to the mass per unit volume of rock (including porosity) of. Depending on the condition of water, depending on the density divided into natural apparent density, natural apparent density, dry density, as the apparent density and saturation. Natural specimen apparent density is in the natural state of an aqueous apparent density. Depending on the density of natural specimens after preparation, storage in the lower part of the dryer storing 1 ^ 2d apparent density. One thousand depending on the density of the specimen at 105-110. Depending on the density of dry under C temperature for 24h. The apparent density is saturated specimens under a saturated water absorption state of apparent density. This standard uses the method and amount of wax seal product method.
