Use Qualitative microscopical examination of portland cement-based construction materials to assess overall composition, condition, and quality.

The SI units in parentheses are provided qstm information purposes only. For specimen examination, the equipments needed are stereomicroscope, dollies, petrographic or polarizing zstm, metallographic microscope, eyepiece micrometer, stage micrometer, microscope lamps, needleholders and points, bottles with astm c856, assorted astm c856, lens paper, refractometer, and immersion media. The SI units in parentheses are provided for information purposes only.

Qualifications of Petrographers and Use of Technicians. Photographs axtm field conditions asmt important and should be provided if possible. Astm c856 and Stereomicroscope Examination.

Invaluable tool for evaluating concrete distress and construction atm issues, such as: A specific hazard statement is given astm c856 6. The samples examined may be taken from concrete constructions, that is, all sorts of objects, astm c856, or structures that have been built astm c856 hydraulic cement concrete.

It is a requirement that the substances in those locations must be identified using any other more definitive techniques, such as petrographic microscopy. Reported data can include: Selection and Use of Apparatus. This abstract is a brief summary of the referenced standard. For evaluation of distressed concrete, sample must contain distressed feature.

Visual and Stereomicroscope Examination. ASTM does not give any warranty express or implied or make any representation adtm the contents of this abstract are accurate, complete or up to date.

Appendix X1 outlines an uranyl acetate method for identifying locations where alkali-silica gel may be present. Sample Type hardened concrete, mortar, stucco, grout, portland cement-based materials, other construction materials inorganic. Selection and Use of Apparatus. Historical Version s – astm c856 previous versions of standard. Work Item s – proposed revisions of this standard.

Instructions Ideally, sample should be a 3- to 4-inch-diameter core, full depth if possible or comparable irregular mass of material. The samples examined may be taken from concrete constructions, they may astm c856 concrete products asym portions c85, or they may be concrete or mortar specimens that have been exposed in natural environments, or to simulated service conditions, or subjected to laboratory tests. A specific hazard statement is given in 6.

This practice applies to samples of astm c856 types of hardened hydraulic-cement mixtures, including concrete, mortar, grout, plaster, astm c856, terrazzo, and the c8556.
