Abstract
Fiber-reinforced concretes with improved strength and deformation characteristics are widely used in construction. The research is aimed to study the stress-strain condition of lightweight fiber-reinforced concrete, to plot stress-strain diagrams and analyze them. In total, four series of prism specimens are manufactured and tested. The first series is the control composition of lightweight concrete; the second series is lightweight concrete with a basalt fiber content of 3%; the third series is lightweight concrete with a glass fiber content of 3 %; the fourth series is lightweight concrete with a basalt fiber content of 1.5 % and 1.5 % glass fiber. The experimental studies demonstrate that lightweight concrete reinforced with basalt fiber has the highest deformability. In comparison with glass fiber, basalt fiber has a higher tensile strength and a higher elastic modulus. The fact that the concrete matrix and basalt fiber work together better is primarily due to the best mechanical characteristics of the basalt fiber. Further research prospects are determined in terms of determining the adhesion strength of various types of fibers with a matrix and studying the effect of this indicator on both the strength and deformation characteristics of lightweight concrete.
