Improvement in Technology of Preparation of a Cement Mortar with Modified Basalt Micro-Fibers
Technological methods for preparation of the cement solution with modified basalt micro-fibers (MBM) have been studied. Optimal sequences of introducing components and the methodfor 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 established.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 preparingthe 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 homogeneityof the mortar are improved. Developed compositions and technological methods for preparing the cement-sand mortar with modified basalt micro-fibers are used when developing thetechnological regulation and recommended for construction of monolithic floors of industrial buildings.
