Improvement in Manufacturing Technology of Basalt Fiber Concrete with Increased Uniformity
Technological methods for preparing the basalt fiber concrete mix with increased uniformity are studied. It is established that 5% of basalt fibers of cement mass is an optimal contentensuring the uniform distribution of fibers in the concrete volume, the growth of compression strength of concrete by 51.2% and tensile strength by 28.8%. In the course of microscopicstudy of basalt fiber, new formations on the surface of basalt fibers are revealed; it shows the increase in adhesion of cement stone to fibers. The introduction of basalt fibers in the concretemix significantly improves the uniformity of concrete quality indicators.
