Studying the thermal insulation capacity of multi-layer reinforced concrete wall panels with an internal layer by low thermal conductivity concrete

Abstract

The issue of climate change and global warming poses an urgent problem for science in general and construction science and technology in particular to ensure comfort in human life. The
development of science, technology and new materials allows the manufacture of covering structures that not only meet the requirements for load-bearing capacity, but also ensure good sound and heat insulation requirements for buildings. construction. In today's article, the authors present the research results on the thermal insulation ability of multi-layer reinforced concrete structural panels with a middle layer using low thermal conductivity concrete materials. Based on the results of heat transfer analysis through various types of structures in climatic conditions in Vietnam using finite element software ANSYS, the study shows the thermal insulation effectiveness of concrete structures. Multi-layer reinforced cardboard with a middle layer from low thermal conductivity material. From there, the research allows to propose and apply this type of structure in the actual conditions of our country.
