“…The expanded polystyrene concrete (EPSC) is often used as a subfloor, a roof pitch layer [1,2] or in fire retardant membranes in construction [3]. Some attempts were made to apply the EPSC for the production of precast wall elements [4].…”

The paper describes damages, tests and repair of the floor made on existing ceiling and expanded polystyrene concrete underlay. The floor was built on a reinforced concrete ceiling with an area of about 1050 m2. Significant damage in the form of cracks, detachments and unevenness was found in the floor. In order to determine the causes of damage, in situ tests and laboratory tests were carried out. It was found that the damage was caused by numerous performance errors. A test repair of the damage (4.7x6.0 m) was carried out, and then the repair method was applied on the entire floor surface.

“…The heat transfer was experimentally measured and the results were verified using a 3D component of COMSOL Multiphysics software. The research by [25] aims at simulating the process of spatial heat transfer in a multilayer non-uniform structure of an external cast-in-place framed wall produced from polystyrene concrete with a stay-in-place formwork. Based on the physico-mathematical model developed with the use of ANSYS and COMSOL software complexes, parametric analysis of the impact of various factors on thermal behavior of the external wall was performed with the account of heat-stressed frame elements.…”

This paper is devoted to modelling of temperature distribution and its time evolution in rooms with specific thermal insulation and heat transfer for different external conditions. The simulation results should help to design the room architecture and wall materials to reduce energy losses due to heating or cooling, and to increase the inside thermal comfort. For this purpose, a methodological procedure using real data processing in the COMSOL Multiphysics modelling environment and spatial visualization of temperature evolution is proposed. This paper describes a mathematical model for simulation of the temperature evolution inside a space with thermally insulated walls under selected outside conditions. Computer simulations are then used to assess the temperature distribution inside the room and the heat flow through the room walls. Results of the simulations are used for subsequent determination of the time needed for the desired decrease of air temperature inside the tested room during its cooling due to the low ambient temperature, which is related to the thermal stability of the building, specific heat capacity, and thickness of the thermal insulation. Under the studied conditions, the time to reach the temperature drops by 20 percent in a room with windows was from 1.4 to 1.8 times lower than that in the room without windows. The proposed methodology shows the flexibility of computer modelling in the design of insulated building systems. The mesh density testing was performed by comparing the air temperature evolution in the model of the selected mesh density and the model with its maximum value enabled by the size of computer memory. The maximum temperature deviation calculated for the mesh of the presented model was 0.57%.

In this paper we analyze contemporary solutions of external wall structures made of cast-in-situ concrete with the use of stay-in-place formwork panels. The advantages of these systems are to reduce the labor input and construction period and to obtain a variety of architectural and planning concepts for buildings. Such systems are widely used in the world. This study is aimed at solving the issues of energy efficiency of external walls with the use of stay-in-place formwork. Some of the most common design solutions are considered. To determine the energy-efficient solution to the stay-in-place formwork option, we used the method of numerical simulation of heat flow processes in structures using the ELCUT 5.1 program. Based on the data obtained, the following results were achieved: an analysis was made of the applied technologies of stay-in-place formwork used to increase the energy-saving characteristics of residential buildings; the thermo-technical characteristics of the selected solutions by numerical simulation were analyzed.
