Impact of plasticizers’ types on the performance of calcium aluminate cement
Source abstract
Abstract
Nowadays it is almost impossible to design a cement-based mixture without the application of some plasticizing additives. There have been developed many types of plasticizers, but they are mostly directed for Portland cement applications. In the case of calcium aluminate cement (CAC), they are also widely employed, but their impact has not been properly studied yet. In this paper, four different bases of plasticizers are investigated through the view of their impact on the composition of hardened CAC paste and on the physical properties of CAC composites as well. The most convenient additive for refractories was found to be plasticizer based on modified polycarboxylates. For the application of CAC at ambient temperature the best solution was the polycarboxylates. However, the dosage of latter have to be performed carefully, because these mixtures are susceptible to bleeding. On the other hand, the melamine-formaldehyde resin was assessed as an unsuitable plasticiser for CAC.
