The article presents a study of innovative materials in the field of highly mobile and cast concrete mixtures using pipeline transport. The studies were carried out on mixtures with a complex additive based on S-3 superplasticizer. The complex included a plasticizing-air-entraining additive LHD with an air-entraining effect. Studies of the effects of S-3 and LHD additives on the construction and technical properties were carried out on mixtures with different cement flow rates and the same initial mobility. Studies of the rheological parameters of the mixtures were carried out using the mathematical theory of experimental design; measurements of resistivities were performed depending on the flow velocity. The result of the work is a linear dependence of the change in resistivities along the length and height.
