| Title of the article | Perfection of technology of concreting of monolithic constructions |
| Abstract. | Problem statement. The article provides an analysis of existing systems, the method of warming up of reinforced concrete structures. It is shown that during the concreting of rectangular columns, the zone of columns angles characterized by a low concrete quality than in other areas, causing an increased defect in these areas. In order to eliminate the existing shortcomings in the article proposes the construction formwork for concreting monolithic columns. Results. During the stripping column often occurs corners peeling with the reinforcement exposing. Also during the columns exploitation its corners are the most vulnerable part at random shock or static loads on them. Repair and restoration of the appearance and protective properties of concrete in the columns at the corners often necessitate the use of special materials or a method of repair is significantly high cost construction. Conclusions. The studies found that the cause of reduced quality of the concrete is a leak joints of formwork elements and lower curing temperature of concrete at low temperatures, and low temperature in the corners of columns, which is a consequence of the lack of current warming systems that do not take into account the uneven warming on its own concrete heat when hardening, as well as increased heat in the corners of columns. |
