An improved flowability can be achieved by the addition of superplasticizers (SP), such as polycarboxylate ethers (PCE). In order to be able to use these PCEs effectively and in a variety of ways and to make them resistant to changes in the environment, it is crucial to understand the influence of SPs on cement hydration. For that reason, the topic of this paper was the incompatibility of a specific SP and an ordinary Portland cement (OPC). The incompatible behavior was analyzed using rheological tests, such as the spread flow test and penetration test, and the behavior was compared by means of an ultrasound technique and explained by the phase content measured by in-situ X-ray diffraction (XRD) the heat evolution measured by calorimetry, and scanning electron microscope (SEM) images. We showed that the addition of the SP in a high dosage led to a prevention of the passivation of the most reactive and aluminum-containing clinker phases, aluminate and brownmillerite. This induced the aluminate reaction to take place in the initial period and led to an immediate stiffening of the cement paste and, therefore, to the complete loss of workability. The results showed that in addition to the ettringite, which began to form directly after water addition, hemicarbonate precipitated. The fast stiffening of the paste could be prevented by delayed addition of the SP or by additional gypsum. This fast stiffening was not desirable for SPs, but in other fields, for example, 3D printing, this undesirable interaction could be used to improve the properties of printable mortar.<\/jats:p>","DOI":"10.3390\/ma13040977","type":"journal-article","created":{"date-parts":[[2020,2,21]],"date-time":"2020-02-21T10:49:16Z","timestamp":1582282156000},"page":"977","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["Investigation of the Incompatibilities of Cement and Superplasticizers and Their Influence on the Rheological Behavior"],"prefix":"10.3390","volume":"13","author":[{"given":"Ursula","family":"Pott","sequence":"first","affiliation":[{"name":"Department of civil engineering, Building Materials and Construction Chemistry, Technische Universit\u00e4t Berlin, 13355 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cordula","family":"Jakob","sequence":"additional","affiliation":[{"name":"Department of Geography and Geosciences, GeoZentrum Nordbayern, Friedrich-Alexander-University, 91054 Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Jansen","sequence":"additional","affiliation":[{"name":"Department of Geography and Geosciences, GeoZentrum Nordbayern, Friedrich-Alexander-University, 91054 Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00fcrgen","family":"Neubauer","sequence":"additional","affiliation":[{"name":"Department of Geography and Geosciences, GeoZentrum Nordbayern, Friedrich-Alexander-University, 91054 Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1893-6785","authenticated-orcid":false,"given":"Dietmar","family":"Stephan","sequence":"additional","affiliation":[{"name":"Department of civil engineering, Building Materials and Construction Chemistry, Technische Universit\u00e4t Berlin, 13355 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,2,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"230","DOI":"10.1016\/j.cemconres.2018.04.017","article-title":"The early hydration of OPC investigated by in-situ XRD, heat flow calorimetry, pore water analysis and 1H NMR: Learning about adsorbed ions from a complete mass balance approach","volume":"109","author":"Jansen","year":"2018","journal-title":"Cem.
