Discussion [of] Modeling Portland Blast-Furnace Slag Cement High-Performance Concrete. Paper by Carlos Videla and Cristian Gaedicke

This brief commentary reports on a study (Videla and Gaedicke, 2004) that focused on Portland blast-furnace slag cement high performance concrete (HPC), with specified 28-day compressive strengths of 60-110 MPa. The study showed it is possible to develop a general compressive strength model combining a hyperbolic equation for strength evolution and an exponential equation for mixture design parameters. In this commentary, Luther contends that the major cementitious component used in the study could not have been an ASTM C 595 Type IS Portland blast-furnace slag cement. Type IS cement, by definition, contains from 25 to 75% slag. The major-component cement used in the study was reported as containing 20% slag. A brief author's closure is appended to this commentary. In the closure, the authors reiterate that the cement used in the study was blended cement with a slag content of 20%. The authors agree with the commentary author that the cement used in the study should have been called slag-modified Portland cement, Type I (SM), according to ASTM C 595.
