摘要

Because of its porous nature, pervious concrete cannot be tested using standards developed for traditional concrete. To fill this need, ASTM International Committee C09 on Concrete and Concrete Aggregates is developing a series of proposed test methods for the substance. The first of these standards, ASTM C1688/C1688M, Test Method for Density and Void Content of Freshly Mixed Per- vious Concrete, has now been approved. This new standard and other proposed test methods for pervious concrete are under the jurisdiction of ASTM Subcommittee C09.49 on Pervious Concrete. Michael Davy, market development manager for CEMEX, and chair of the C09.49 task group that developed ASTM C1688/C1688M, says that the new standard can be used as a means of verifying that the pervious concrete delivered to a project corresponds to the producer's mix proportions. ASTM C1688/C1688M may also be used in the development of mixtures with various aggregate types.
