Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.
Last previous edition approved in as C — Further discussion of these and other technical issues is given in the Appendix. Combining values from the aztm systems may result in non-conformance with the standard. Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3.
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.
Print and complete the following order form. Mix the solution on the day before use, cover, and store at Method C is suitable for evaluating portland cements but not blended cements or blends of portland cement with pozzolans or slags. 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.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Use a water-cement ratio by mass of 0. Enviado por Murilo flag Denunciar.
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.
For mortar bars 25 by 25 by mm volume mLthis is to mL of solution per mortar bar in the storage container. Maintain the volume proportion of sulfate solution to mortar bars in a storage container at 4. A number in parentheses indicates the year of last reapproval. Other sulfate concentrations or other sulfates such as MgSO 4 may be used to simulate the environmental exposure of interest.
ASTM C1012/C1012M – 18a
Determine the pH of the solution before use; reject the solution if the pH range is outside 6. 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. Further discussion of these and other technical issues is given in the Appendix.
