ASTM C 403/C 403M - 08 Standard Test Method for Time of Setting of Concrete Mixtures by Penetration Resistance

American Society for Testing and Materials (ASTM). Current edition approved April 1, 2008. Published May 2008. 7 p. This test method covers the determination of the time of setting of concrete, with slump greater than zero, by means of penetration resistance measurements on mortar sieved from the concrete mixture.
This test method is suitable for use only when tests of the mortar fraction will provide the information required.
