Use a water-cement ratio by mass of 0. Such chemicals shall conform to the specifica- tions of the Committee on Asstm Reagents for the American Chemical Society where such specifications are available. For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container.
Instructions Supply 5 kg sample. Support the bars so that no end or side asrm a bar rests against the container. C — 04 Standard Test Method for Length Change of Hydraulic-Cement Asrm Exposed to a Sulfate Solution1 This standard is issued under the fixed designation C ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

Work Item s – proposed revisions of this standard. Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. Sample Type portland cement, blended cements, and supplementary cementing materials blended with portland cement. A number in parentheses indicates the year of last reapproval. Use This test provides a means of assessing the sulfate resistance of a mortar.
Unless otherwise directed the c0112 solution contains moles of Na2SO4 per m3. Order Form 2 Email complete form asgm contact listed below.
The length change of mortar bars immersed in sulfate solution is the indicator. Reagents and Materials 5. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.

Other sulfate concentrations or other sulfates such as MgSO4 may be used to simulate the environmental exposure of interest. Other sulfate concentrations c1021 other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest. Test Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. Maintain the volume proportion of sulfate astk to mortar bars in a storage container at 4.
Last previous edition approved in as C — Can extend time of testing for additional charge. The values shown in parentheses are for information purposes only. Referenced Documents aatm separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Combining values from the two systems may result in non-conformance with the standard. Results Produced Length change of mortar bars immersed in sulfate solution. When tests are made that are expected to produce results that are close to an acceptance- rejection value, it is recommended that reagent grade chemi- cals be used. Enviado por Murilo flag Denunciar. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Further discussion of these and other technical issues is given in the Appendix. Within the text, the inch-pound units are shown in brackets. A superscript epsilon e indicates an editorial change aztm the last revision or reapproval.

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.
Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. Seal the container with a lid so that the sulfate solution cannot evaporate.
Any anhydrous or hydrated sodium sulfate may be used if the water content of the salt is checked by loss on ignition and proper corrections made to account for the specified asym concen- tration.
