If you need more info or have any questions, please note the Lab ID number and contact us at:. Test 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.
It is the responsibility of the c1021 of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.
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. If you need more info or have any questions, please note the Lab ID number and contact us at: Order Form 2 Email complete form to contact listed below. Determine the pH of the solution before use; reject the solution if the pH range is outside 6.

A number in parentheses indicates the year of last reapproval. Can extend time of testing for additional charge.
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.
Testing goes to 1 year. Method C is suitable for evaluating portland asmt but not blended cements or blends of portland cement with pozzolans or slags.

Use This c112 provides a means of assessing the sulfate resistance of a mortar. Historical Version s – view previous versions of standard. Significance and Use 3.
Any anhydrous or hydrated sodium sulfate may be used if the water content adtm the salt is checked by loss on ignition and proper corrections made to account for the specified sulfate concen- tration. Originally approved in Unless otherwise directed the exposure solution contains moles of Na2SO4 per m3. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Instructions Supply 5 kg sample.

Support the bars so that no awtm or side of a bar rests against the container. Such chemicals shall conform to the specifica- tions of the Committee on Analytical Reagents for the American Chemical Society where such specifications are available. The length change of mortar bars immersed in sulfate solution is the indicator.
Combining values from the two systems may result in non-conformance with the standard. Time for Results Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.
Other sulfate concentrations or other sulfates such as Satm may be used to simulate the environmental exposure of interest. Enviado por Murilo flag Denunciar.
