Polymer Fibers in Foam Concrete Application Efficiency

Abstract:

The urgency of improving the performance properties of concrete, as the most common building materials, is noted. The reasons for the increased demand for products made of high-strength gas-filled concrete are stated. It is shown that the current volume of polymer fibers production makes it possible to predict the possibility of their widespread use in construction. The information on the physical and mechanical properties of synthetic fiber, which is important for its successful use as dispersed reinforcement of foam concrete mixtures, is presented. The technology of manufacturing experimental samples and methods of their testing are described. It has been established that the introduction of any synthetic fiber into the foam mixture formulation improves the structural properties of foam concrete, however, the measure of efficiency depends on the ratio between the concrete moduli of elasticity and fiber. The greater the value of the elastic modulus of the fiber used, the higher the technical effect of its use in fiber-reinforced concrete for structural purposes can be.
