The analysis of the efficiency of six types of slabs has been carried out, which differed in material, internal form and weight. The comparison and the comparison of the same in size, but different in constructive characteristics and materials of floor slabs are considered and performed.
This paper presents a method and algorithm for finding effective thermal characteristics of composite materials, with complex internal structure by the method of thermal-electrical analogies based on the discrete model that built for the task of analysis of the temperature field by finite element method.
This paper is devoted to the results of deformation characteristics of concrete and reinforced foam concrete with fiber polypropylene fiber. Tests were carried out by the standard method and a method based on the values of equality elastic modulus of concrete in compression and tension using a chart based "stress-strain".
