Summary:Formulations of composite retardands of flowability loss, based on a polysiloxane emulsion and an acid admixture, were developed. The influence of the content of the ingredients and of the sequence of introducing the superplastricizer and retardant on the technological properties of concrete mixes and concretes plasticized with Stachement-2000 polycarboxylate superplasticizer was examined.
