Content of magnetic minerals for manufactured sand (mean [s.d.] value of χ = 736 [386] × 10–8 m3 kg−1) is higher than for river sand (χ = 105 [122] × 10–8 m3 kg−1). Such high values of χ seem to be more favorable for properties of concretes, and hence they lead to a better replacement product. ... Download PDF. Innovative ...
