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…

ASTM International has published a new American National Standard, ASTM E2659 , Standard Practice for Certificate Programs. This standard provides much-needed guidance to certificate issuers on how to develop a quality certificate program and to consumers on how to identify such a program. In addition, the standard is designed to serve as the benchmark of quality for industry accreditation of…

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…
