Sampling
• The new stockpile can now be sampled at even intervals.
• Material is obtained from each location with a shovel bydigging into the pile.
• The FOUR increments are then combined to comprise thefinal field sample.
With Power Equipment
Concrete Plant Quality Control Technician Course, Grade 2
If power equipment is not available:• The stockpile is checked for segregation
(and noted in log).• The pile is visually divided into three
even sections.• Portions are obtained from each section
at least 12” below the surface byremoving the outer layer of material.
• The three increments are then combinedto comprise the final field sample.
Without Power Equipment
