There have been several changes and updates in important ASTM standards affecting concrete producers. Committee members approved five new ASTM Standards at December's ASTM committee meetings. Here is a brief update on these changes:
C114 – Standard Test Methods for Chemical Analysis of Hydraulic Cement has been revised to C114-06.
C1252 – Standard Test Methods for Uncompacted Void Content of Fine Aggregate (as Influenced by Particle Shape, Surface Texture, and Grading) has been revised to C1252-06.
C1622/C1622M – Standard Specification for Cold-Weather Admixture Systems has been revised to C1622/C1622M-06.
C511 – Standard Specification for Mixing Rooms, Moist Cabinets, Moist Rooms, and Water Storage Tanks Used in the Testing of Hydraulic Cements and Concretes has been revised to C511-06.
C76 – Standard Specification for Reinforced Concrete Culvert, Storm Drain, and Sewer Pipe has been revised to C76-06.
To help producers learn about these and other new standards, ASTM's Web site includes a document summary page. You can access all of this information by visiting www.astm.org. You only need to enter the standard designation number, such as C1207, in the site search.
The ASTM staff also announced that committees are beginning discussions on four work items. They are:
WK13439 – Test Method for Total Sulfur in Concrete.
WK13453 – Standard Specification for Liquid Membrane-Forming Compounds Having Special Properties for Curing and Sealing Concrete is a work item revision to existing standard C1315-06.
WK13455 – Standard Test Method for Determining Consistency and Density of Roller-Compacted Concrete Using a Vibrating Table is a work item revision to existing standard C1170-06.
WK13475 – Standard Specification for Packaged, Dry, Combined Materials for Mortar and Concrete is a work item revision to existing standard C387/C387M-06a.
Producer involvement in these standard discussions is vital. To learn how to become a committee member, telephone ASTM at 610-832-9585 or e-mail email@example.com. The staff will direct you to the appropriate committee chairman.
