New Specification for Anti-Washout Admixtures for Concrete

1. Scope

(1) The assembling and study of data pertaining to the properties of hydraulic-cement concrete and its constituent materials, including the study of the effect of characteristics of materials and mixture proportions upon the properties of concrete; and (2) the development of standards for concrete and for the constituent materials of concrete (except cement), as well as for certain related materials, such as materials used in curing or repair of concrete.
2.2 The scope of the Committee does not include the field of design and construction of concrete structures except insofar as references need to be made to construction methods in special cases of concrete as “over- the-counter” material.

NOTE: In accordance with an agreement between ASTM and the American Concrete
Institute (ACI), ACI will refrain from specification writing for “over-the-counter” engineering materials and ASTM will refrain from standardization efforts in design and construction practice.


admixtures; concrete; performance requirements; anti-washout; underwater placement


This specification will be used to qualify admixtures as being suitable to reduce the loss of fine particles from concrete being placed underwater without having any significant adverse effects on normal concrete properties.

The title and scope are in draft form and are under development within this ASTM Committee.
