GeoPrac and ASTM Standards Updates

ASTM standards are an important part of my geotechnical engineering practice, and keeping up with changes can be a challenging thing. Their website offers an ASTM standards tracker service that will email you a weekly update on new, revised or otherwise modified standards for your areas of interest. I try to sift through these weekly updates and provide a monthly update to GeoPrac readers that contains changes to standards (no work items) that may be of interest to them in their practice. I look at updates from the following ASTM comittees:

• C01 – Cement
• C07 – Lime
• C09 – Concrete and Concrete Aggregates
• C15 – Manufactured Masonry Units
• C17 – Fiber-Reinforced Cement Products
• C18 – Dimension Stone
• C27 – Precast Concrete Products
• D04 – Road and Paving Materials
• D18 – Soil and Rock
• D19 – Water
• D35 – Geosynthetics
• E07 – Nondestructive Testing
• E27 – Hazard Potential of Chemicals
• E44 – Solar, Geothermal and Other Alternative Energy Sources
• G01 – Corrosion of Metals
