Stable aqueous supersaturated suspensions of aluminum sulfate or basic aluminum sulfate containing an aluminum complexing agent, useful as setting accelerators for cement compositions

摘要

By including a complexing agent in the composition the risk of crystal separation and of its homogenous nature is avoided. An aqueous supersaturated solution of aluminum sulfate of concentration at least 26%, relative to water + aluminum sulfate, also containing an aluminum complexing agent,is claimed. An Independent claim is also included for the use of such a suspension.
