  • Ways of development of resource-processing enterprises of the regional investment and construction complex

    To solve the economic, technical, environmental and social problems of the region, it is expedient to create a regional inter-branch finance and construction forestry cluster (IFSLP). The creation of a regional IFSLP facilitates the most effective use of the integration process in the allocation of investment resources in the region. Cluster education allows: - to create investment attractiveness of the region; - to organize new jobs - to attract young professionals with higher education - to use innovative developments - to increase deductions to the local budget - to clean the forest from dead wood and substandard timber, to generate heat and electricity, - to create a competitive export product.

  • Investigation of the corrosion resistance of stabilized sandy loam soils in corrosive environments

    Investigations were conducted to assess the corrosion resistance of stabilized sandy loam soil with ground granulated slags in organic media: mineral oil, gasoline and diesel fuel. A model is proposed for an accelerated study of the corrosion resistance of concretes and other building materials under the conditions of the dynamic effect of the medium under investigation on the test material. The obtained results of X-ray phase analysis of samples and electron microscopic studies suggest that as a result of hydration of minerals of ground slag and ground, low-base CSH (B) hydrosilicates are formed, the sizes of new formations and inclusions on ETF slag are less than on CMP slag.
