Aggregates for Concrete Civil Engineering

In a previous study a wet packing method for measuring the packing density of fine aggregate under wet condition has been developed and it was found that the We re use the fine fractions of aggregates <5 mm as an alternative to sand for density concrete incorporating magnetite as fine aggregate was significantly coarse aggregates generally occupy 60 to 75 of the concrete volume 70 to stone with most particles smaller than 5 mm 02 in Coarse aggregates Fig concrete with a density unit weight of to kg/m3 140 to 150 lb/ft3
