Without stirring the contents of c298 container, decant the remaining free liquid into the crucible. A number in parentheses indicates the year of last reapproval.
Precision and Bias The difference between this determination and that previously obtained represents the amount of SiO2. A potentially deleterious degree of alkali X1.

This standard is subject to revision at satm time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. Some form of petrographic examination is essential; it can often obviate the need for any further testing, and it will identify the most pertinent sequence of tests required and help in the correct interpretation of results.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Test method Subject Areas: To download astm e pdf, click on the c2289 button. A specific precautionary statement is given in 5. HF can cause very severe burns and injury to unprotected skin and eyes.
NOTE 6—The mass of the empty crucible may be determined if one wishes to know asmt magnitude of impurities in the residue of SiO2. Preparation of Calibration Curve May 28 Protect the dry reagent and solution from contamination by carbon dioxide. Sims, I Publication Date: Astm c standard test method for potential x289 reactivity of aggregates chemical method standard number. E57 3d imaging format reference implementation of the astm 3d imaging format. The astm a is a c298, complicated for studies, events and other description weeks.
Astm international, formerly known as the american society for testing and materials astm, is a globally recognized leader in the development and delivery of. The 4 C — 03 method is particularly applicable to rapid control analysis of crystalloidal silica below 10 ppm. ASR, on the other hand, is more common because of a greater number of aggregates that contain reactive silica astk. For the other test solutions, it can be eliminated.
Astm has also produced a standard mortar bar test method, astm c astm,and a standard chemical method, astm c astm, b, for the assessment of aar. Allow the solution to stand for 5.
Containers with wall thickness not less than 0. Astn 1—All dimensions are in mm. Astm b 04 pdf free download astm international. These aggregates should be considered to indicate a potentially deleterious degree of reactivity until the innocuous character of the aggregate is demonstrated by service records or by supplementary tests in accordance with the provisions of Test Methods CCor Cas applicable.
At present, there is little practical guidance regarding the assessment of potential alkali-aggregate reactivity given in the various national standards. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
However, potentially deleterious aggregates represented by points lying above the dashed line in Fig. Astm c compressive strength hydraulic cement mortars.
Mel C. Marshall Industrial Consultants Inc.
If the solution is not clear, filter through a fine-texture paper. Read the concentration of silica in the solution directly from the previously prepared calibration curve correlating transmission of light of this wave length with silica concentration. The mass fraction ranges of the elements listed have been established through cooperative testing 2 x289 reference astm e pdf.
Last previous edition approved in as C — Approved July 10, Sometimes aggregate assessment is based on specific tests which may not be appropriate to the materials in question. We need your help to maintenance this website. Reactive forms of silica in the aggregate High-alkali pore solution Sufficient moisture Even though aggregates may contain reactive forms of silica, there will be no alkali-silica reaction if the alkali content of the cement is low, or if the finished concrete product is not exposed to excess moisture.
Standard volumetric flasks, burets, and pipets should cc289 of precision grade. From where can i download a pdf copy of astm standards. Do not aastm the results of tests by this qstm method as the sole basis for acceptance or rejection for sources with regard to ASR. We are a non-profit group that run this website to share documents.
Please fill this form, we will try to respond as soon as possible. Store the solution NOTE 2—In selecting the container, take care to ensure that the reagent will not be modified by reaction with the material composing the container, including pigments or other additives, or by transpiration of phases through the walls of the container. Please help us to share our service with your friends. Store the solution in a chemically resistant glass container see Note 2. Compressive strength of cylindrical concrete specimens1 this standard is issued under the.
Then apply and adjust the vacuum to approximately 51 kPa.
Use a mL aliquot of the solution to determine its SiO2 content by the procedure described in 8. Potential alkalisilica reactivity of aggregate chemical method.
