Reviewer 2 Report

 

 

The manuscript concerns the development of a green hydraulic ternary system binder based on waste phosphogypsum (PG) for a development of sustainable high-performance construction materials.

The topic is interesting and the paper is well structured. A physical and mechanical characterization is presented in the paper. The manuscript can be reconsidered for publication if the following points are fully addressed in a revised version of the manuscript.

  • - General comment

The authors should improve the literature review citing other research papers presented in international journals dealing with this topic and extend the introduction with more recent and relevant papers. 

Minor Points

- In Figure 3, the letters c) and d) are written in a different font from a) and b). Please check.

- In Figure 5b, for the labels and the tick values please use the same font of the other figures
