Analysis of the Synthetic Fiber Influence on the Cement Stone New Formations Composition in Foam Concrete

Article Preview

Abstract:

The relevance of the search for scientifically grounded tools, with the help of which it is possible to ensure the growth of crack resistance and strength of foam concrete, is noted. The systemic need of the building complex for energy-and resource-saving operationally reliable building materials is emphasized. The positive influence of the surface energy potential of the fibrous fiber of polymer and carbon composition on the possibility of forming an improved structure of the cement stone in the composition of the interpore partitions of foam concrete has been scientifically substantiated. The article provides information on the foam mixtures formulation and the timing of their hardening. The scans of the investigated materials’ X-ray diffraction patterns and the identification table of the detected hydration neoplasms of the cement stone are presented. The scientific substantiation reliability is experimentally confirmed by the results of the analysis performed, from which it follows that all foam concretes contain quartz, portlandite, hydro-aluminates and calcium hydro-silicates. It has been established that the introduction of fiber into the foam mixture formulation creates the prerequisites for the appearance of such varieties of the hydrated silicate phase as nekoite, which has a fibrous structure at the nanoscale, and foshagite, which has an acicular structure of crystals with increased hardness. The listed mineral hydrated new formations of cement stone, due to their individual properties, should contribute to the foam concrete operational properties’ improvement.
