mar 01, 2003 steel furnace slag a by-product of steelmaking, has higher density than conventional basalt aggregate due to the presence of iron influxes 5,6 when the crushed gravel is subjected to five cycles of the sodium sulfate soundness test the weighted loss shall not exceed mass percent. when crushed slag is used, it must be of uniform density and quality and shall have a density not less than 1120 kgm as determined by aashto 19.separation of crushed slag according to bulk density separatsiya shlakovogo shchebnya po obemnonu vesu. translation lcpc from russian to french. after mentioning specification governing the bulk density of crushed slag according to the gost standards, the author briefly explains the theoretical principles of particle separation for acteristics of steel slag cement were better than those of crushed limestone aggregate. similarly, some of the physical properties of steel slag aggregate concrete were better than those of crushed limestone aggregate concrete, though the unit weight of the former was more than that of the latter. study obtained by shaopeng et al. aimed unit weight of crushed coal products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, unit weight of crushed coal, quarry, aggregate, and different kinds of minerals.
mar 01, 2013 steel slag contains significant amounts of free iron, which gives the material high density and hardness and makes it as a suitable artificial source of aggregates for road construction It can be used as an aggregate in surface layers and in unbound bases or oct 31, 2012 physical properties and geometrical morphologies of crushed air-cooled blast furnace slag and crushed limestone were comparatively investigated. the shape, angularity, surface texture and internal pore structure of aggregate particles for different size and gradation were numerically represented by sphericity and shape index angularity number index of
