Abstract: Extended Annotation 1. Body of Annotation The Master’s Qualification Thesis (MQT) is devoted to the development of reconstruction process of the workshop of vibro-pressed products manufactured by the method of semi-dry shaping on the basis of super-hard concrete mixtures. The development of this scientific and technical problematics contains: - state assessment of the load-bearing structures of a part of the concrete products workshop, where reconstruction is not provided; - installation of a pavement structure unit of 132 square meters in the area where the industrial workshop building elevates to the level of +10.60 m; - execution of a deepening of a concrete power reinforced floor by -1.00 m in order to install a curing chamber of freshly formed vibro-pressed products in the workshop; - arrangement of handling system of freshly formed concrete products into the curing chamber is performed of sandwich panels using mineral wool in the middle of two sheets of profiled galvanized flooring; - calculation of special vibration isolation in the process of concreting a foundation slab for a moulding vibropress MASA XL 9.1; - thermotechnical calculation of the parameters of the bearing and filling elements of curing chamber of finished products using the BASE computer software complex; - scientific justification when choosing the optimal set of construction machines and mechanisms for the reconstruction of the concrete products workshop in Myliatychi village of Lviv region; - design of technological processes of the main reconstruction and construction works when installing a curing chamber; - development of an effective construction plan for the implementation and organization of construction at this facility; - determination of the reconstruction cost using the ABK-3 software package in the form of design specifications and estimates; - introduction of measures for labour occupational safety and environment protection, which will need to be organized in the process of performing repair and reconstruction works. 2. The object of research: reconstruction of the workshop of vibro-pressed concrete products is given above and the subject of research is determined, namely, the replacement of technological equipment with a modern complex of steam curing of freshly formed concrete figured paving elements. 3. Goal of research: development of an effective method of production facility reconstruction for introducing the industrial method of concrete products vibrocompression on a modern concrete-forming complex of the brand "MASA" XL 9.1 with curing chamber of finished building elements manufactured by "ROTHO". 4. The result of the scientific and technical research carried out in this Master’s Qualification Thesis is the development of an optimal technology for the performance of reconstruction and repair works in order to increase production capacity for the manufacture of high quality concrete figured paving elements in a significantly larger number of finished products of high architectural expressiveness. At the same time, in the process of reconstruction, it was proposed to use modern industrial concrete-forming equipment of the MASA XL 9.1 brand and to use a special curing chamber manufactured by Rotho (Germany). 5.
