The article analyzes the traditional accounting systems in construction. The analysis was conducted from a survey of 135 construction companies on 10 indicators. The analysis allowed to identify four models and recommend them for the following methods of organization and the participants of the construction process: - an integrated system with a single accounting management accounting (construction activity);-uniform accounting analytically the (investment and construction activities);-uniform accounting general orientation (participants in the implementation of investment projects);-boiler method is not recommended.

Keywords: Financial accounting, construction, accounting systems, financial accounting model, the formula cost, accounting algorithm.

  The analysis of the effectiveness of duration of electric vibration treatment of foam concrete mixture is carried out. The optimum fraction of filler for preparation of foam concrete mixture processed by variable electric field is defined. The influence of a type of cementitious matter by means of a comparison of domestic cement and Turkish (CEM I-42,5R) cement is analysed. It is established that at a short-term electric vibration treatment of foam concrete mixture there is a consolidation of the material of interporous partitions that leads to some increase in strength of foam concrete.
