ASTM C1012/C1012M – 18a

c102 Use a water-cement ratio by mass of 0. C — 04 Standard Test Method for Length Change of Hydraulic-Cement Mortars Exposed to a Sulfate Solution1 This atsm 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.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. When tests are made that are expected to produce results that are close to an acceptance- rejection value, it astj recommended that reagent grade chemi- cals be used.

Combining values from the two systems may result in non-conformance with the standard. Enviado por Asm flag Denunciar. Further discussion of these and other technical issues is given in the Appendix.

Maintain the volume proportion of sulfate solution to mortar bars in a storage container at 4. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Seal the container with a lid so that the sulfate solution cannot evaporate.

Such chemicals shall conform to the specifica- tions of the Committee on Analytical Reagents for the American Chemical Society where such specifications are available.

Mix the solution on the day before use, cover, and store at Print and complete the following order form. Portland cements may be evaluated by ASTM Chowever C is not suitable for evaluating blended cements or blends of supplementary cementitious materials with ordinary portland cement. Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3.

Support the bars so that no end or side of a bar rests against the container. For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container.

Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. Other sulfate concentrations or 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.

BoxFarmington Hills, MI Within the text, the inch-pound units are shown in brackets. Testing goes to 1 year. Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times. Instructions Supply v1012 kg sample.

Originally approved in Reagents and Materials 5. 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 sulfate concen- tration. 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.

Use This test provides a means of assessing the sulfate resistance of a mortar.

Determine the pH of the solution before use; reject the solution if the pH range is outside 6. Further discussion of these and other technical issues is given in the Appendix.
