Get PriceBulk Density Testing. Bulk density () can be defined as the ratio of the mass of the refractory specimen to its bulk volume (which includes the volume of the pore spaces). Bulk density gives an indiion of the porosity of the refractory substance, low indies high porosity and likewise low strength of the material, and vice versa ...
Get PriceThe test is performed after a preshear step which will give a certain density of powder prior to applying the normal stress and the shear. This preshearing can be varied which will give different results. Those different results will be used to draw different yield locus and subsequently calculate different properties of the powder (see below).

Get Price1. Scope. This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.
Get PriceTest procedures are similar, but the laboratory compactive effort of the modified method is higher. Using a 10lb () hammer with 18in () freefall instead of the () hammer with 12in () drop. This results in higher maximum soil densities at lower optimum moisture contents. The modified Proctor is used today ...
