Bulking Of Fine Aggregate What Why Amp How

Feb 11, 2014 The volume increase of fine aggregate due to presence of moisture content is known as bulking. Fine sand bulks more as compared to coarse sand. Extremely fine sand particularly the manufactured fine aggregate bulks as much as about 40. Note Fine aggregate do not show any bulking when it is absolutely dry or completely saturated.
