3 sample size

The sample size has the following types .A-shaped .230mm x 114mm x 64mm; B-shaped .230mm x 64mm x 54mm;

C-shaped 230mm x 64mm x 64mm; D-shaped. 160mm x 40mm x 40mm.

The width of the sample preparation as the test height, deviations should be recorded, C, D-shaped specimen molding surface should be marked. In addition to ramming

Materials and dry materials, the sand can be used to prepare hammer hammer 50mm diameter and height of 50mm +/- 1mm of the sample, a variety of materials, sample size
