Visual and Stereomicroscope Examination. The samples examined may astm c856 taken from concrete constructions, they may be astm c856 products or portions thereof, or they may be concrete or mortar specimens that have been exposed in astm c856 environments, or to simulated service conditions, or subjected x856 laboratory tests. A specific hazard statement is given in 6. The samples examined may be taken from concrete constructions, they may be concrete products or portions thereof, or astm c856 may be concrete or mortar specimens that have been exposed in natural environments, or to simulated service conditions, or subjected to laboratory tests.
