GENERAL INFORMATION ON METHODS OF REINFORCEMENT ANCHORING IN CELLULAR CONCRETE

Abstract

The requirements of the modern world and the construction industry in particular pose challenges to humans in the development and production of energy-efficient and environmentally friendly building materials. Cellular concrete can be considered one of these building materials. Due to its structure, it has such desirable properties as thermal insulation, frost resistance, sound insulation, low water absorption, non-toxicity, etc. At the same time, unfortunately, it has a rather significant disadvantage for the construction industry - insufficiently high mechanical strength. Because of this, it is quite problematic to use cellular concrete as a material for the manufacture of structural elements, especially span structures. That is why these types of concrete are mainly used as a material for filling self-supporting enclosing structures, on which external influences and loads are minimized. This problem can be partially solved by rigid or flexible rod reinforcement of structural elements made of cellular concrete with or without the use of dispersed reinforcement. Due to the low physical and mechanical properties of this construction material, there is a risk that the reinforcing bars may be pulled out of the cellular concrete massif when an external load is applied to a structural element made of such material. Reliable anchoring of reinforcing bars in an array of cellular concrete is of great importance for solving the problem of operational reliability of structural elements. The article discusses the currently known methods of anchoring reinforcement bars in an array of concrete of various types using different design solutions or with the use of additional elements or devices.
