Abstract
Disclosed is a flow improving agent for binder suspensions containing cement which is composed of a) amino-s-triazine-formaldehyde-sulfite condensation products having a molar ratio of amino-s-triazine:formaldehyde:sulfite of 1:1.3 to 6.0: 0.3 to 1.5 and a low content of free formaldehye as well as b) casein. The flow improving agents have the advantage that the flowability is considerably improved compared to casein (alone) for example and the increased flowability remains constant even over a longer time period.
