Model: MBV-2

Standards: EN933-9/1999

Description

The Methylene blue value (MBV) test set is used to determine the swelling clay content in fine aggregates thus to evaluate the aggregate cleanliness degree. This test is suitable for aggregate size less than 2.36mm or 0.15mm, when the 0.075mm sieving test through rate less than 3%, then no need to perform this test.
