bending

A research stand has been developed to conduct research on the phenomena that accompany the bending of cardboard / paper during the manufacture of the bottom part of food containers and containers. A universal experimental stand for studying the pro­ perties of corrugated cardboard has been adapted to another material – folding card­ board; a program of experimental research has been developed aimed at determining the linear specific load when bending a flat material by 90 degrees perpendicularly and across paper fibers.

The article is devoted to the study of carrying capacity and bending deflections of fiber-reinforced non-autoclaved foam concrete structures reinforced by steel ropes. The relevance of such research caused by the fact that the implementation of protecting and supporting structures of reinforced foam concrete is economically efficient. The greatest heat loss in buildings observed through the so-called “cold bridges”, which include window and door lintels. Implementation of cellular concrete lintels solve the problem of insulation.
