The lightweight aggregate type and associated volume fraction mix is determined by the lightweight concrete density. In traditional mixing process of concrete, the minimization of the density clearly required high volume fraction which will causes aggregate segregation. The multi stage casting procedure occupy inserting lightweight (LW) aggregates in casing following satisfying in residual interstitial void by means of cementations grout with a low density. Consequently, these methods produce low compressive strength and enhanced weak point. Thus, the suggested casting technique could have a practical for developed non-structural rudiments and structural compound that require minimum density. The results show promising methods to support many projects that required strength more than 20 MPa for house slabs, driveways and footpaths.
