| description | The current stage of development of building materials science is characterized by the widespread use of dispersed reinforcement of various compositions and sizes in mortars and concretes. In the paper, priority scientific and technical directions for the rational use of reinforcing fibers, including secondary ones, was established for the effective development of resource and energy-saving technologies and the production of competitive commercial products in the construction industry. A study of the phase formation of concrete using technogenic fibrous materials was carried out. Using scanning electron microscopy for the obtained samples, a positive effect of the introduced additive to the packing density of the new formations of the composite with a simultaneous micro-reinforcing effect was revealed. According to the results of X-ray diffraction analysis, in samples using technogenic fibrous materials, the processes of dissolution of clinker minerals are activated with a simultaneous decrease in Ca(OH)2 reflections, which indicates its binding to hydrate neoformations CSH. Identification of CSH hydrated phases is noted by differential thermal analysis, where the release of bound water from the CSH hydrogel is due to the deepest endo effect at temperatures around 90–110 ºС. The high-temperature exoeffect with a maximum at 899 °C is associated with gel crystallization into low-basic calcium silicate hydrate modifications. Thus, the structure formation of highly effective cement materials was controlled through the use of technogenic fibrous materials such recycled basalt wool. At 28 days aged, compressive strength of the cement composites rises to 26%, and flexural strength up to 62% by applying recycled basalt wool waste. |
