The main results of the research are to find numerical solutions for selecting effective fixed formwork material for columns and analysis of technological operations. The use of fixed formwork of glass-magnesite sheet allows improving quality and stability of the structure, increase fire resistance, which helps to extend the life of the concrete structure. Based on numerical and experimental studies, a model of the formwork fastener for a round column of 3 m high, with a diameter 500 mm was developed. A calculation model was created and the design of the formwork made of glass-magnesite sheet was calculated. So, for the diameter of the concrete column from 300 to 600 mm, the thickness of the glass-magnesite sheet varies in the range: 7-23 mm. A workflow has been developed for the installation of fixed formwork and for concreting columns with the determination of the required amount and type of work, with the determination of the complexity; a workflow for the quality control of work has also been developed. Such periods as: accepting of elements of fixed formwork, installation of fixed formwork elements, accepting of timbering construction operations must be monitored.
The aim of the study is to identify the main features and correlation of the organization of construction building site in extreme climatic conditions by modeling organizational and technological solutions applied energy-saving technologies. A model of a mobile wind, electric, diesel station consisting of separate blocks: solar panels, wind turbines and a diesel power plant is developed. Recommendations on energy saving, which will increase energy efficiency during the construction of buildings and structures in extreme climatic conditions are proposed. The importance of the results for the construction industry is the possibility of improving the quality of construction of buildings and structures in extreme climatic conditions with reducing work force, material-technical and fuel-energy resources and adverse environmental impacts.
In our country at the modern stage of the development of constructional industry the necessity arises in qualitative ceramic wall materials. The use of this items provides durability, comfort and architectural expressiveness for constructions. In connection with what is an acute problem of use of “low-grade” clay raw material for production of high-quality wall ceramic products. The solution of problem is to activate clay raw materials in various ways. One of relatively simple, effective and economically expedient methods of the activation of clay raw material is mechanical activation. It is used to improve the quality of dense metamorphisized clay raw materials. But it is not enough, therefore it is offered to hold extra chemical activation by adding chemical additives in raw mixtures. The purpose of present research is to study mechanism of increasing the strength of the ceramic crock affected by the fluxing additive, imputed in raw mixtures proportion based on medium-plastic clay raw materials. To achieve the given purpose, it is necessary to solve the following tasks: a) to investigate influence of fluxing additives on rheological raw mix behavior; b) to study modification mechanism of changing the properties of ceramic crock by adding fluxing additive into the raw mixtures.
This work aims to develop effective technology for erecting monolithic enclosing structures of buildings made of expanded polystyrene concrete. As a result of the research carried out, a model of large-panel formwork made of ABS plastic for concreting monolithic walls with an expanded polystyrene concrete mixture was developed, representing rectangular panels of a size of 3000 x 1200 x 40 mm. To ensure the necessary strength and rigidity, the outer side of the formwork is made cellular with a large number of longitudinal and transverse stiffeners placed in increments of 300 mm. We have developed a technology for erecting monolithic enclosing structures of buildings made of expanded polystyrene concrete using a mobile concrete-mixing unit. The following are technical and economic indicators for manufacturing monolithic walls out of expanded polystyrene concrete of a volume of 46 m3 : the cost is 354.784 thousand rubles, and the labor intensity and unit capacity are 163.76 people.*h and 27.36 units.*h, respectively. The results significantly offer the construction industry a solution to reduce the labor intensity of construction and installation while manufacturing cost-effective monolithic enclosing structures for buildings.
