Influences of temperature on interactions between superplasticizers and cements with several main constituents

The aim of this research project was to determine interactions between superplasticizers and cements in the temperature range of 5 °C (41 °F) to 30 °C (86 °F). The main focus was on superplasticizers based on polycarboxylate ether and cements with several main constituents.
