The article considers the dynamics of the general physical properties of soils for lands that have been released at different times from various types of agricultural use. The research was carried out in the Chebarkul district of the Chelyabinsk region. В статье рассмотрена динамика общих физических свойств почв для земель, вышедших в разное время из-под различных видов сельскохозяйственного пользования. Исследования проведены в Чебаркульском районе Челябинской области.

The aim of this paper is the collection, processing and statistical analysis of data from the results of testing concrete cube samples which are tested in the Laboratory for materials of the Faculty of Civil Engineering, University of Belgrade, in the period from 2012. to 2017. year. For the needs of the analysis, the data from the Report on testing of control concrete cubes were taken, the basic characteristics of hardened concrete are also classified. Statistical analysis of the date of concreting, age of samples, composition of concrete, volume mass, pressure strength, required concrete marks etc have been carried out. The statistics showed that the most commonly used cements were the following markings: CEM II A-M (V-L), CEM II A-M (S-L), CEM II A-S, with the highest share of concrete mark MB 30 with 66,8% and MB 40 with 14,3 % stake.
