    Abstract

    ASTM C 1157 has undergone several changes since it was first adopted in 1992 as a performance specification for blended cement. Those changes have increased the number of available options and broadened the scope of the standard to include portland cement. However, the level of acceptance and use of ASTM C 1157 by specifiers and manufacturers remains limited. Barriers to acceptance include a disinterest or lack of familiarity with the specification, the slow process for adopting the specification in referencing standards and building codes, concerns with respect to test methods, and difficulties in interpreting the standard. For example, it has been noted that the strength requirements are unusually complex due to the wide range of options available.

    A Task Group of National Ready Mixed Concrete Association (NRMCA) and Portland Cement Association (PCA) members has been reviewing C 1157 and has suggestions for revisions to address concerns raised. These potential changes and their rationales are discussed. Included are: reexamination of strength requirements, evaluation of test methods, modification of some provisions, and suggestions for additions to the standard.
