Article analysis:

This article is generally reliable and trustworthy in its discussion of the development of 3D concrete printing (3DCP) composites with reduced cement consumption through partial replacement with supplementary cementitious materials (SCM). The authors provide a detailed overview of their research process, including an explanation of their methodology, mix design, composition execution, and printing system. They also provide evidence to support their claims by citing previous studies that have successfully achieved similar results.

The article does not appear to be biased or one-sided in its reporting; rather, it presents both sides equally by discussing both the potential benefits and drawbacks associated with reducing cement consumption in 3DCP mixtures. Additionally, all claims made are supported by evidence from previous studies or from tests conducted during this research project.

The only potential issue is that some points of consideration may be missing from the discussion; for example, there is no mention of possible risks associated with using SCMs as partial replacements for Portland cement in 3DCP mixtures. Additionally, there is no discussion about how different types or amounts of SCMs may affect the properties of the composite or how they may interact with each other when used together. These points should be explored further in future research on this topic.

In conclusion, this article is generally reliable and trustworthy in its discussion of reducing cement consumption in 3DCP mixtures through partial replacement with SCMs. All claims made are supported by evidence from previous studies or tests conducted during this research project, and all potential biases are avoided by presenting both sides equally. However, some points of consideration may be missing from the discussion which should be explored further in future research on this topic.
