Test models concrete mixtures’ drying behavior, augments slab specs

Source: ASTM International, West Conshohocken, Pa.

Newly published ASTM C1792, Test Method for Measurement of Mass Loss Versus Time for One-Dimensional Drying of Saturated Concretes will enable engineers and producers to characterize how hardened mixtures dry. “The information provided can be used to directly assess the drying rates of a given concrete mixture,” says ASTM member Dale Bentz, chemical engineer for the Materials and Structural Systems Division in the National Institute for Standards and Technology Engineering Laboratory. “[It] could be valuable for industrial flooring applications, for example, where a quick drying is often desirable.”
