Sampling methods SAMANCTA
Sampling may be carried out using a vacuum pump (Sampling tool L01-01), various pipette-type samplers (Sampling tool L03-01) or other appropriate samplers e.g. Sampling tool L04-01 or Sampling tool L05-01. If samples are to be taken from only one barrel, the final samples are poured directly from the sampler into the sample containers. When a set of barrels are to be sampled and we are certain ...

Glass Cullet an overview ScienceDirect Topics
Glass cullet from the crushing of post-consumer glass is readily available in urban areas. It can be added in small quantities (probably 20%) into many mixes, but its smooth surface means that it is difficult to achieve a good bond with the surface. Glass dust is a hazardous irritant, so appropriate health and safety precautions must be taken (see Section 7.4.3).
