Measurement of setting time

Q. How is time of setting of concrete measured?

A. There are several methods for measuring setting time, among them are the following:

- Standard Test Methods for Time of Setting of Hydraulic Cement by Vicat Needle (ASTM C191)

- Standard Test Method for Time of Setting of Concrete Mixtures by Penetration Resistance (ASTM C403)

- Standard Test Method for Time of Setting of Hydraulic-Cement Paste by Gillmore Needles (ASTM C266)

- Standard Test Method for Time of Setting of Grouts for Preplaced-Aggregate Concrete in the Laboratory (ASTM C953)
