Aggregates in civil construction

Aggregates are conventionally granular material available naturally. Alluvial deposits (rivers, lakes and ponds) are common natural aggregate sources (sand and gravel). However, the most production of natural aggregates worldwide is from hard rock sources found in quarries and underground mines. It may also be crushed by reclamation of waste products, Iron/ steel slag obtained in steel …

Dry Density - an overview | ScienceDirect Topics. The following graph depicts the difference of maximum dry density on diverse percentages of RHA with sample A. High dry density values decrease with the increase in percentage quantity of RHA, from 1780 kg/m 3 to 1595 kg/m 3.This is due to the addition of RHA, which has a lower specific gravity (SG) as compared to soil (Fig. 12.5).
