The effects of nanomodifying additives on technological and operational characteristics of cement concretes

The article presents the study results of the effects of modified nanoadditive polycarboxylate plasticizer Melflux 1641 F on the rheological and strength characteristics of cement concrete. The study showed that the concrete mixture brand could be improved on its workability by means of the proposed modification method without the compressive strength reduction. The study demonstrated a reduction of the expensive polycarboxylate plasticizer Melflux 1641 F consumption due to its modification by the additive ANKU 2. Depending on the requirements to the mobility of concrete mixtures, the consumption of plasticizer could be reduced from 19 to 43%, with the largest savings of Melflux 1641 F observed in mixtures of highly mobile brand P5.
