INFLUENCE OF POLYMER SUPERPLASTICIZERS ON VARIOUS TYPES OF CARBON NANOMATERIALS

The article presents the results of a study of various types of carbon nanomaterials introduced into polymer superplasticizers and tests of the obtained additives in concrete. It has been established experimentally that during the growth of crystals they partially penetrate into each other and form a spatial network that pierces the entire cement stone and connects it into a single whole, due to which the compressive strength of concrete increases up to 30%. Moreover, the introduction of a plasticizer makes it possible to achieve a high water-reducing eff ect (30% and more) and leads to the appearance of a plasticizing eff ect at low and superlow water–cement ratios
