ASTM International Committee C09 on Concrete and Concrete Aggregates is currently developing a proposed standard that addresses bleed stability. ASTM WK28156 , Test Method for Bleed Stability of Cementitious Grout Under Static Pressure, is under the jurisdiction of ASTM International Subcommittee C09.41 on Hydraulic Cement Grouts. When cementitious grouts bleed, mixing water separates from the…, ASTM Committee C09 Next Meeting:, Dec. 6-8, December Committee Week, New Orleans, La., Technical Contact:, Fred Goodwin, BASF Construction Chemicals, Cleveland, Ohio, Phone: 216-839-7009; fred.goodwin@basf.com, ASTM Staff Contact:, Scott Orthey, Phone: 610-832-9730; sorthey@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8648

ASTM International Subcommittee E34.50 on Health and Safety Standards for Metalworking Fluids has developed three new standards. Two of the recently approved ASTM standards cover aspects of water-miscible metalworking fluids, while the third concerns prevention of dermatitis in the wet metal removal fluid environment., Prevention of Dermatitis, Dermatitis is an inflammatory response of the skin to a chemical or physical agent. While redness, swelling and itching are typical signs of dermatitis, symptoms can be more severe as well. A new ASTM standard, ASTM E2693 , Practice for Prevention of Dermatitis in the Wet Metal Removal Fluid Environment, discusses dermatitis and its causes and presents a comprehensive approach to dermatitis…, Metalworking Fluids, Two new E34.50 standards address the detection of microbial contamination in metalworking fluids: ASTM E2657 , Test Method for Determination of Endotoxin Concentrations in Water-Miscible Metalworking Fluids, and ASTM E2694 , Test Method for Measurement of Adenosine Triphosphate in Water-Miscible Metalworking Fluids. Both ASTM E2657 and ASTM E2694 measure biological contamination in metalworking…, Participation Invited, The subcommittee is currently looking for participants for an interlaboratory study for ASTM E2657 and ASTM E2694 . “We plan to use a single set of MWF for both standards, so labs who are interested in either or both are welcome to participate,” says Passman. “A few labs will run both the ILS’s for both standards, while most will run one or the other.” Subcommittee E34.50 is part of ASTM…

A proposed new ASTM International standard, ASTM WK22233 , Test Method for Indication of Concrete’s Ionic Conductivity, describes a five-minute nondestructive test that has the potential to replace a destructive six-hour test requiring several hours of preparation time. The proposed standard is being developed by Subcommittee C09.66 on Concrete’s Resistance to Fluid Penetration, part of ASTM…

Shrinkage that occurs during the drying process is a major cause of cracking in concrete. However, application of shrinkage-reducing admixtures in the field has been yielding positive results, and engineers have realized that admixtures can mitigate cracking. A new ASTM standard currently being developed by Subcommittee C09.23 on Chemical Admixtures will set minimum standards for an admixture to…

Because of its porous nature, pervious concrete cannot be tested using standards developed for traditional concrete. In order to fill this need, ASTM International Committee C09 on Concrete and Concrete Aggregates is developing a series of proposed test methods specific to pervious. The first of these proposed standards, ASTM C1688/C1688M , Test Method for Density and Void Content of Freshly…
