Structural Features of the Cement-sand Mortar Reinforced with a Modified Basalt Microfiber

Abstract

Use of modified reinforcing fibers that are dispersed in the mortar mixture increases the strength properties of a stone mortar. This happens due to the formation of structures and determines the need to study this phenomenon. Study of the mortar stone structure was carried out by comparing the samples of the reinforced solution and the solution without reinforcement. Investigation of the slurry microstructure revealed that administration of a modified microfiber basaltic composition in the solution reduces the number and size of pores, cracks, defects. This is due to the fact that upon the presence of a carbon nanomodifier the acerous calcium silicate neoplasms are formed, which fill the voids in the stone structure, thus sealing its. The interface reinforcing microfibers and a cement-sand matrix is characterized by a tight grip thereby increasing the efficiency of the particulate reinforcement in the cement. The results of the X-ray diffraction data confirm the electron microscopy data. They also point to the growth rate of tumors gel (calcium hydrosilicate type C-S-H (I and II). The established features of the structure of the cement-sand mortar, which is a modified basalt microfiber reinforcement allow us to explain increase in physical and mechanical properties of the dispersion-reinforced mortar.
