While the use of internally cured concrete in construction is not new, there is now better understanding of the internal curing process and why IC using pre-wetted lightweight aggregate increases concrete durability and service life in an economical and practical way. However, there is not currently a standard for lightweight aggregates for internal curing. ASTM International Committee C09 on…

ASTM International Committee E07 on Nondestructive Testing has recently approved three new standards on phased arrays, polymer matrix composites for aerospace applications and digital imaging. The committee will be meeting in Plantation, Fla., on Jan. 24-28 and welcomes participation in its standards developing activities., Ultrasonic Methods, Thousands of portable phased array units, used for weld inspections, have now been sold worldwide. There are many benefits to these devices, including speed, cost, imaging, flexibility and setups, along with no radiation, licensing or contamination. Despite these advantages, there was not a universal inspection procedure for phased array inspection of welds. A new standard, E2700 , Practice for…, Specialized NDT Methods, A new guide gives an introductory overview that describes how mature and established nondestructive testing methods that are routinely used by industry are applied specifically to the characterization of polymer matrix aerospace composites. E2533 , Guide for Nondestructive Testing of Polymer Matrix Composites Used in Aerospace Applications, is under the jurisdiction of Subcommittee E07.10 on…, Digital Imaging and Communication in Nondestructive Evaluation, A new standard developed by Subcommittee E07.11 on Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) will fill a need in the nondestructive testing industry for a transparent and industry standard data format with which to store digital inspection data. E2663 , Practice for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Ultrasonic Test Methods…, WK17435,, Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for X-Ray Computed Tomography (CT) Test Methods;, WK17436, , Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Digital Radiographic (DR) Test Methods;, WK20537, , Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Eddy Current Test Methods; and, WK22505,, Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) for Computed Radiography (CR) Test Methods. ASTM International standards can be purchased from Customer Service (phone: 610-832-9585; https://www.astm.org/contact/ ).

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…
