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.
