In modern construction when constructing the monolithic flooring, mortars on the basis of Portland cement are widely used. A system shortcoming, which predetermines the loss in operating properties, is low resistance to the abrasion of cement-sand composite. Results of the experimental study of the influence of dispersed reinforcement with modified basalt microfiber (MBM) on the dusting of cement mortars used for monolithic flooring are presented. It is shown that the increase in the content of MBM in the composite by 0.5% of the weight of the binder leads to the reduction in the abradability value of the mortar by 46.9% on average. The increase in the content of MBM in the composition of mortar leads to the reduction in the abradability of the cement mortar. The established result makes it possible to predict the use of the dispersed reinforced mortar for the little dusty floor covering to which high requirements for abradability are set.
