Characterization data of reference cement CEM III/A 42.5N used for priority program DFG SPP 2005 "Opus Fluidum...

Area of Science:

• Materials Science
• Civil Engineering
• Chemical Engineering

Background:

• Reference cements are crucial for standardized research within scientific programs.
• The German Research Foundation's Priority Program 2005 (DFG SPP 2005) selected two reference cements for comparative studies.
• Previous work characterized CEM I 42.5 R; this study focuses on the complementary reference cement.

Purpose of the Study:

• To present comprehensive characterization data for the reference cement CEM III/A 42.5 N.
• To detail the chemical and mineralogical compositions of CEM III/A 42.5 N.
• To report on the physical and chemical properties of CEM III/A 42.5 N and its slag constituent.

Main Methods:

• Chemical analysis to determine elemental composition.
• Mineralogical analysis (e.g., X-ray diffraction) to identify crystalline phases.
• Physical property testing (e.g., setting time, strength) and chemical property assessment.

Main Results:

• Detailed chemical composition of CEM III/A 42.5 N and its slag component.
• Mineralogical composition including clinker phases and slag phases.
• Reported physical and chemical properties with calculated mean values and errors.

Conclusions:

• The presented data provide a reliable baseline for CEM III/A 42.5 N.
• This characterization supports ongoing research within DFG SPP 2005.
• The data are valuable for external researchers utilizing the same reference materials.
