SPP 2005 Working Group Analytics

A thorough characterization of starting materials is the precondition for further research, especially for cement, which contains various phases and presents quite a complex material for fundamental scientific investigation. In the “Analytics” group of SPP 2005, the characterization of the reference cementitious materials and superplasticizer were collected based on tests conducted by many research groups involved in this cooperative program. For all data received, the mean values and the corresponding errors were calculated. The results shall be used for the ongoing research within the priority program of the German Research Foundation (DFG SPP 2005).

Goals

Working Group Analytics in SPP 2005 conducts the thorough characterization of the reference raw materials and put forward the reliable solutions to the problems in the experiments caused by the materials. In detail, WG Analytics has the following goals:

  • Interlaboratory characterization of reference materials: cements, SCMs and superplasticizers
  • Data sharing within the priority program
  • Providing essential data for the modelling work
  • Tests of material ageing during storage

Results and Current Work

The major achievement of the working group “Analytics” contains the following two parts:
  1. Three published paper on the characterization data of the reference materials in SPP 2005
  2. Organized keynote presentations with different topics for all the SPP members, especially the early researchers and Ph.D candidates
Regarding the first part, two papers on the detailed characterization data of CEM I 42.5R and CEM III/A 42.5N were published in Data in Brief (ISSN 2352-3409) from the aspect of chemical and mineralogical composition, physical properties and performance. In addition, one paper on the characterization of the reference superplasticizers was also published in the same journal. For the second part, the following keynote presentations were organized during the seminar & workshop of the group “Analytics”.
  • 01.2019, Particle Characterization, Dr. Ingo Kampen (TU Braunschweig)
  • 01.2020, Interactions between particles (in the presence of polymers), Prof. Regine von Klitzing (TU Darmstadt)
  • 01.2020, Interaction of admixtures with cementitious materials, Dr. Zichen Lu (TU Berlin)
  • 09.2020, A real multiscale challenge – The long way from material analysis at the nano level to macroscopic fresh properties of cement-based materials Interactions. Prof. Dirk Lowke (TU Braunschweig)
