ASTM C1567 − 13 Standard Test Method for Determining the Potential Alkali-Silica Reactivity of Combinations of Cementitious Materials and Aggregate Accelerated Mortar-Bar Method

ASTM C1567 − 13 Standard Test Method for Determining the Potential Alkali-Silica Reactivity of Combinations of Cementitious Materials and Aggregate Accelerated Mortar-Bar Method

Scope

1.1 This test method permits detection within 16 days of the potential for deleterious alkali-silica reaction of

combinations of cementitious materials and aggregate in mortar bars.

The cementitious materials are composed of various proportions of hydraulic cement, pozzolans and ground granulated blast furnace slag.

1.2 The test results are only valid for the specific combinations of pozzolan, slag, and reactive aggregates tested.

1.3 This test is not suitable for evaluating the potential for deleterious reaction of combinations of hydraulic

cement and aggregate (that is, in the absence of pozzolans or ground granulated blast-furnace slag).

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard

Significance and Use

4.1 This test method provides a means for evaluating the ability of pozzolans and ground granulated blast-furnace slag to control deleterious internal expansion due to alkali-silica reaction when used with an aggregate intended for use in concrete.

It is based on the Accelerated Test Method developed at the National Building Research Institute (NBRI) in the Republic of South Africa (1-4).
