    Jan 01, 2021 In this study, Ni 3 Al was added to SiC to improve its relative density, microhardness, and fracture toughness. The addition of Ni 3 Al promoted the densification of SiC at low temperature. The microhardness and fracture toughness of the SiC sample with 10 wt% Ni 3 Al improved 174.55% and 27.29% compared to those of the sample without Ni 3 Al.

    Relative density (specific gravity) is also used in die computation of voids in aggregate. Relative density (specific gravity) (SSD) is used if the aggregate is wet, that is, if its absorption has been satisfied. Conversely, the relative density (specific gravity) (OD) is used for computations when the aggregate is dry or assumed to be dry.
