Technological methods for preparation of the cement solution with modified basalt micro-fibers (MBM) have been studied. Optimal sequences of introducing components and the meth- od for mixing the mortar mix, which provide the uniform distribution of MBM in the solution and improvement of the homogeneity of parameters of concrete quality, have been estab- lished. The method for preliminary separation of basalt micro-fibers in the liquid medium, which provides the increase in the bending strength by 64.1%, is proposed. When preparing the mortar mix with modified micro-fibers in the mixer of a rotor high-speed type, using the alternate method of loading of initial components, strength characteristics and homogeneity of the mortar are improved. Developed compositions and technological methods for preparing the cement-sand mortar with modified basalt micro-fibers are used when developing the technological regulation and recommended for construction of monolithic floors of industrial buildings.
