ASTM R0028 - Manual of Cement Testing (This is not an ASTM standard; available as PDF, only)

1.1 The Manual of Cement Testing is intended to supplement-not in any way to supersede-the various ASTM standard methods of sampling and physical testing of hydraulic cement. This manual was prepared by Committee C-1 on Cement and has been accepted by the Society for publication as information only. The manual is not a part of the ASTM methods.

1.2 It is the purpose of this manual to emphasize those factors which may affect results of tests, and to call attention to less apparent influences which are important but which are sometimes overlooked.
