The paper presents technology of monitoring a reinforced concrete pillar-connector of prefabricated walls. Prefabricated units made from a modified Polytech mortar containing expanded polystyrene derived from recycling were used to build a residential object. Reinforced concrete pillars that serve as wall connectors in Polytech system are load-bearing elements. In order to control the reinforced concrete connector of prefabricated walls under realistic conditions, a control technology was applied that involved int...

The paper describes a technology of controlling a prefabricated wall made of new material called Polytech used to produce prefabricated units. Prefabricated units made from a modified Polytech mortar based on expanded polystyrene derived from recycling were used to build a single-family residential building. Prefabricated elements are provided as wall panels. In order to control the prefabricated wall under realistic conditions, an innovative control technology was suggested that involved installation of a fiber B...

The paper describes technology of monitoring a joist slab used in a single-family residential building constructed in the Polytech system. Prefabricated units made from a modified mortar based on expanded polystyrene derived from recycling were used to manufacture building walls. The joist slab is based on prefabricated walls, by means of a reinforced concrete tie beam. In order to control the tie beam under realistic conditions, a monitoring technology was suggested that involved introducing fiber Bragg gratings ...

The paper describes the technology of controlling a new material called Polytech used for the production of prefabricated units. Prefabricated units made from a modified Polytech mortar based on expanded polystyrene derived from recycling were used to build a residential object. Prefabricated elements are load-bearing and, at the same time, insulating elements in the form of wall panels. In order to control the prefabricated wall with a lintel under realistic conditions, a control technology was suggested that inv...

The paper presents a system monitoring operational safety of structures used in civil engineering. The system is based on the fibre Bragg grating (FBG) sensors or sensors using the optical time domain reflectometry (OTDR) technology. The essence of the solution is to introduce FBG sensors into the structure to make them act as its пїЅnervous systemпїЅ. The system may be implemented in existing civil engineering structures made of steel, concrete, reinforced concrete, as well as in shells and new structures at the ...

Modern prefabricated buildings, constructed according to the innovative Polytech technology are to be energy-saving and enable quick completion of the investment project. The new construction method uses load-bearing and, at the same time insulating, elements in the form of prefabricated panels made from the modified Polytech mortar. However, until today, the detailed data regarding the strength and deformability of important Polytech elements have not been verified. The new Polytech system has not been investigat...

The paper presents a system for monitoring of operational safety of ferromagnetic structures used in civil engineering, machine construction and power engineering. The system is based on sensors of the residual magnetic field (RMFM) distribution. A change in values of individual components of the residual magnetic field informs in advance about the appearance of areas with a raised level of stresses or stress concentration zones and identifies micro cracks. The paper presents numerous examples of identification of...

The paper describes the possible applications of expanded polystyrene (EPS) granulate derived from recycling for the production of prefabricated building units. Test results of a new material called Polytech and its application in the construction industry are presented. Polytech construction system is based on prefabricated large-panel units. An important advantage of the new material is the volume representation of EPS granulate, which reaches up to 60%. So far пїЅ in order to keep the proper strength of the man...

New innovative smart adaptive materials and optical measurement system can be implemented in civil engineering. Smart materials can be especially used in cased where fast and efficient way of reduced vibrations, weight and deflections is required. The essence of the solution is to introduce FBG sensors into the structure to make them act as its пїЅnervous systemпїЅ. The system may be implemented in existing civil engineering structures made of steel, concrete, reinforced concrete, as well as in shells and new stru...
