Photographs of field conditions are important and should be provided if possible. A photographic chart of materials, phenomena, and reaction products discussed in Sections 8 — 13 and Tables 1- 6 are astm c856 as Adjunct C ADJC It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. A specific hazard statement is given in 6. Active view current version of astm c856.
Invaluable tool for evaluating concrete distress and construction materials issues, such as: Print and complete the following order form. It is informational only and not an official part of the standard; the full text astm c856 the standard itself must be referred to for its use and application.

Historical Version s – view previous versions of standard. This practice applies to samples of all types of hardened hydraulic-cement mixtures, including concrete, mortar, grout, plaster, stucco, terrazzo, and the astm c856.
Link to Active This link will always route to the current Active version of the standard. Visual and Stereomicroscope Examination. Astm c856 SI units in parentheses are provided for information purposes only.
Appropriate procedures for the sampling, preparation, and aetm astm c856 specimens are detailed methodically. Each report specifically addresses the client? Selection and Use of Apparatus.
The samples astm c856 may be taken from concrete constructions, that is, all sorts of c85, units, or structures that have been built of hydraulic cement concrete.
Work Item s – proposed revisions of this standard. The samples examined may be taken from concrete constructions, they may be concrete products or astm c856 thereof, or they may be astm c856 or mortar specimens that have been exposed in natural environments, or to simulated service conditions, or subjected to laboratory tests.
Reported data can include: The SI units in parentheses are provided for information purposes only. Project specifications such as maximum water-cement ratio, minimum air content, and concrete mix design are also helpful. ASTM does not give any warranty express or implied or make astm c856 representation that the contents of this abstract are accurate, astm c856 or up to date.
This practice outlines the standard procedures for performing petrographic examination of hardened concrete samples.

Results Produced Written, satm report; may contain tabulated data. Instructions Ideally, sample should be a 3- to 4-inch-diameter core, full depth if possible or comparable irregular mass of material. They may also be concrete astm c856 or portions thereof, or concrete or mortar specimens that have been exposed in natural environments or simulated astm c856 conditions, or subjected to laboratory tests.
Appendix X1 outlines an uranyl acetate method for identifying locations where alkali-silica gel may astm c856 present. Qualifications of Petrographers and Use of Technicians. This abstract is a brief atm of the referenced standard. Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual astm c856 needs and testing response times. For evaluation of distressed concrete, sample must contain distressed feature.
ASTM C – 14 Standard Practice for Petrographic Examination of Hardened Concrete
Selection and Use of Apparatus. A specific hazard astm c856 is given in 6. Visual and Stereomicroscope Examination. The samples examined may be taken from concrete constructions, they may be concrete products or portions thereof, or they may be concrete or mortar specimens that have been exposed in natural environments, or to simulated astm c856 conditions, or subjected astm c856 laboratory tests.
It is a requirement that the substances in those locations must be identified using any other more definitive techniques, such as petrographic microscopy. For astm c856 examination, the equipments needed are stereomicroscope, dollies, petrographic or polarizing microscope, metallographic microscope, eyepiece micrometer, cc856 micrometer, microscope lamps, needleholders cc856 points, bottles with droppers, assorted astm c856, lens paper, refractometer, and immersion media.
