Description

This Standard sets out the hot water method for the accelerated curing of compression test specimens of concrete, made in the laboratory or in the field, and prepared in accordance with AS 1012.8.

Scope

The method allows for the transportation of test specimens from the field to a curing tank in a laboratory. Specimens are tested between 23 h and 27 h from time of batching.

Note: Accelerated curing procedures can provide useful information on the quality of concrete on the day after specimens are made. Strength results may be used in a number of ways including the control of quality of production and the prediction of the strength at 28 days.

Any correlation between strength results obtained by these methods and strengths obtained by standard curing should be based on statistical analysis of results for the particular concrete mix as well as materials and curing procedures used.
