Reinforcement of cellular concrete with composite materials

Abstract

Cellular concrete, such as gas silicate or foam concrete, has good thermal performance and is widely used in modern construction. Possessing acceptable parameters for compression, cellular concrete has low tensile and shear characteristics. This leads to the appearance of cracks in building structures made of cellular concrete, such as partitions, interior walls, etc. Therefore, solving the problems of increasing the bearing capacity of cellular concrete is important and relevant. The purpose of this study is to study the increase in the bearing capacity of cellular concrete reinforced with composite materials under the action of temperature and bending moments. The problem is solved by the finite element method and analytical methods. As a result of the work carried out, the characteristics of wall panels reinforced with composite rods were obtained under the action of temperature and bending moments in structure. Composite materials in the form of canvases are widely used to enhance the bearing capacity of aged reinforced concrete structures or those that have received defects due to man-made impacts. Consideration of methods for determining the given characteristics of a multilayer composite canvas is necessary for conducting a study of the bearing capacity of reinforced concrete structures reinforced with composite canvases or canvases. In this paper, methods are presented for determining the given characteristics of multilayer composite canvases and panels with different arrangements of the base layers. The analysis of the obtained results showed that reinforcement of the composite materials can significantly increase the tensile strength and shear of the gas silicate of the building.
