New Test Method for Standard Test Method for Using Temperature Rise as an Indication of Relative Time of Setting of Cementitious Mixtures

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.

Keywords

fraction of temperature rise time; temperature measurement; setting time; early-age hydration

Rationale

This test method uses easily collected thermal data from cementitious mixtures such as concrete or sieved mortar to approximate and compare the relative times of setting under similar curing conditions. It is not necessarily intended to replace the C403 method or other penetration resistance methods or reproduce results obtained using those methods, but it may be an acceptable alternative for many applications and users.

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